Heavyweight Turnout Blankets
A heavyweight turnout carries 300 grams of fill or more under a waterproof shell, so a clipped, senior or hard-keeping horse stays warm and dry through nights in the teens and below, out in wind, rain and snow.

What riders say about their heavyweights
Riders tell us a heavyweight earns its keep in the first hard winter: a horse moved north from a warm climate stays warm in it, and a well-built one survives the blanket wreckers.
I moved my thoroughbred from Florida to Utah in midwinter. He was shivering like a leaf in his old 400g fill heavyweight blanket the first night. I put this on and he was toasty warm in minutes and hasn't been cold since, in wind, snow, and subzero temperatures out in the open at night!
Amigo Bravo 12 Plus Turnout 400g
My horse,Otto, needed to replace his old heavy weight blanket, and I was happy to see the one he wanted at TackoftheDay for a decent price. The Amigo Bravo 12 Plus Turnout is certainly among the best quality blankets on the market, and Otto was pleased it arrived very quickly, just in time for the cold weather!
I purchased the heavy weight blankets because I knew the quality of the lightweight was good. Glad I did! Kept my mare warm and dry. I have purchased other blankets in the past and non compare to the Weatherbeeta horse blankets. I was leary on the olive green color but it was on sale and so I got that one. It is beautiful! Thank you Weatherbeeta for a good quality blanket at an affordable price
Great blanket with durable construction, which is always a must for my blanket wreckers! LOL I have used WeatherBeeta for most of my horse's blankets in the past and now that I'm moving to the East Coast, away from sunny California, a heavy weight was a MUST for my thoroughbreds and so I immediately went to the WeatherBeeta website and quickly found exactly what I needed.
The Heavyweight Edit
How to know a heavyweight is right for your horse
The six sections below cover what the grams mean, the temperatures and horses that call for a heavyweight, when a liner system or a neck cover does the job better, and how to tell your horse is comfortable underneath.
How many grams is a heavyweight turnout blanket?
A heavyweight turnout blanket has 300 grams of fill or more: the University of Maine Extension, Rutgers, Horseware and Equinavia all start the heavy band at 300 g. Most heavyweights sit at 300, 350, 360 or 400 grams, like the Equinavia Arktis Regular Neck Heavy Weight Turnout Blanket 300g and the Rambo Original Turnout 400g, and a few run to 450 grams or more for the coldest, windiest fields.
Grams measure the fill between the shell and the lining, so they tell you warmth; the denier of the outer tells you how well it stands up to a horse that plays rough. A clipped horse in freezing weather is the classic heavyweight job, and riders with fully clipped horses tell us 300 grams under a truly waterproof shell keeps them warm.
| Guide | Light | Medium | Heavy |
|---|---|---|---|
| Maine Extension | 60 to 100 grams (sheets and rain sheets 0) | 150 to 300 grams | 300 grams and up |
| Horseware | 0 to 100 grams: mild cold or a thick winter coat | 150 to 250 grams: fall and early winter | 300 grams and above: severe winter |
| Rutgers | Light sheets for early fall and dry conditions | About 200 grams for moderate cold | About 300 grams for peak winter or a fully clipped horse in severe cold |
| Equinavia | 0 to 100 grams, clipped, above 50 degrees F | 150 to 250 grams from 30 to 40 degrees F; up to 300 grams from 20 to 30 | 300 to 400 grams from 10 to 20 degrees F; plus liners below 10 |
What Riders Say
Really great blanket for freezing temperatures, esp. if horse is clipped. Super warm fill, great waterproofing. Easily adjustable belly and leg straps. Good stitching on blanket. Would recommend for heavy blanket.
This is the only blanket I have ever found that actually covers the chest completely and it is not restrictive at all. I do a full body clip on my mare and this keeps her nice and toasty. Made well and very durable, shes been wearing it for a month and there are no rips or tears, unlike her other blankets. I have purchased blankets from every brand, and this is the best one by far. And she looks fantastic in it!
What temperature calls for a heavyweight blanket?
Reach for a heavyweight when nights fall to 0 to 14°F for a full-coated horse, or 15 to 24°F for a clipped one, by the University of Maine Extension blanketing chart below. Under those ranges the chart adds a liner and a hood on top of the heavyweight.
Treat the chart as a starting point. Wind, rain and a recent move from a warm climate all push the line up, and a wet horse loses warmth at temperatures a dry one shrugs off. Riders in the coldest barns tell us a heavyweight system keeps a horse comfortable even when nights drop well below zero.
| Coat | Temperature | Blanket |
|---|---|---|
| Full coat | 40 degrees F and above | No blanket needed |
| Full coat | 25 to 39 degrees F | No blanket, or a rain sheet if it is wet |
| Full coat | 15 to 24 degrees F | Light or midweight blanket |
| Full coat | 0 to 14 degrees F | Heavyweight blanket |
| Full coat | Below 0 degrees F | Heavyweight blanket, liner and hood |
| Clipped | 40 to 50 degrees F | Rain sheet or lightweight blanket |
| Clipped | 25 to 39 degrees F | Light or midweight blanket |
| Clipped | 15 to 24 degrees F | Heavyweight blanket |
| Clipped | Below 15 degrees F | Heavyweight blanket, liner and hood |
What Riders Say
Best quality blanket I’ve ever purchased!!! Great mud coverage for Oregon rainy weather, and keeps the horse completely dry! I bought 4 of them and the horses are all warm and cozy for winter! Fit my TB and Arab great, and stays put with heavy abuse!
This combination of stable blanket + turnout sheet has been working quite well so far this winter, and it’s been well below zero a couple of times. The best barn staff checked on him and he was cozy and comfortable even when it got super cold. So I’m pleased with the system as it is. He still has another medium-weight that’s a bit big on him that will serve admirably as another layer in the event that it gets even colder (always a possibility, thanks Vermont!).
Which horses need a heavyweight, and which run hot?
Seniors, clipped horses, hard keepers and horses new to the cold need a heavyweight first; a horse that runs hot or lives in a stall usually does not. A senior grows less coat, a clipped horse has lost his insulation and a hard keeper burns feed to stay warm, so each is cold sooner than the full-coated easy keeper beside him.
Fit matters as much as fill for these horses. A mutton-withered or high-withered senior loses warmth where a standard neckline gaps and lets rain run down the shoulder, so look at an extended-neck or high-neck cut such as the Equinavia Arktis Extended Neck Heavy Weight Turnout Blanket 300g. Ponies get the same treatment at a smaller size, in cuts like the Equinavia Norse Pony Turnout Blanket 300g.
| Horse | Why | What riders do |
|---|---|---|
| Senior, or thin-coated | Grows little coat and is more sensitive to wet and wind | Blanket more, add a neck cover, watch for shivering |
| New to a cold climate | Chilly at 30 degrees F if not used to it or wet | Treat as clipped, and move up in weight |
| Hard keeper or skinny horse | Burns calories to stay warm, and loses the warmth of digesting hay when he cannot eat much | Blanket and feed hay |
| Clipped horse | Clipping takes away natural insulation | Replace the hair you took off with an equal amount of blanketing |
| Runs hot | Sweats easily and overheats in a heavier blanket | Lighter fill, a breathable shell, and a cooler after work |
| Stabled indoors | Stacked stable sheet and turnout can run 400 to 500 grams | One layer at a time; take layers off midday |
What Riders Say
We were looking for a heavyweight blanket for one of our favorite ponies. Perfect for our needs and now the pony is very warm and happy being a little "pony burrito" in her new blanket.
I have a mutton withered, senior Arabian. The "standard necklines" on the majority of turnouts don't fit him and rain will seep down his shoulders. After heavy rains his forequarter is often soaked. This turnout sheet fits him beautifully and I'm probably going to order the same style with medium fill for the winter months.
Heavyweight turnout or a liner system?
Choose one heavyweight turnout if your horse lives out through months of deep cold or is boarded where staff change blankets; choose a light shell with liners if the weather swings through several ranges in a week and you do the changes yourself. A heavyweight goes on in the fall and stays on, while a liner system adds or removes 100 to 300 grams without a second outer.
The Rambo Optimo Turnout 0g plus 400g Liner and the Rambo Duo Turnout are both built as an outer plus a liner. One rider runs a 100 g Amigo outer with 100 g and 300 g liners of the same size; another puts a rain sheet over the heavyweight once temperatures drop into the 30s.
| Your situation | Pick | Why |
|---|---|---|
| Weather swings through several ranges in a week and you do the blanket changes | A light or 0g shell plus liners | One waterproof outer carries every band, and you dial warmth up or down with a liner instead of owning a blanket for each range |
| Boarded horse, and staff change blankets by temperature | One heavyweight turnout, or a medium with one liner that stays on | Staff cannot tell at a glance what is under the outer, and limited storage makes extra pieces easy to mix up or forget |
| Only a few truly cold nights each winter | A medium shell with a neck cover, or one liner | You are buying warmth for a handful of nights; a liner or neck piece does that without a second full blanket |
| Months of deep cold and wind, horse out around the clock | A heavyweight turnout | One piece to put on in October and take off in spring, with fill zoned by panel on the Horseware heavies |
| Senior or thin-skinned horse that needs only a little extra on chilly days | A rain sheet with a built-in fleece liner, or a 100g liner | It fills the gap between a rain sheet and a medium without a full blanket change |
| You already own a non-Horseware shell | Check attachment points first, then a liner from the same maker | Horseware states only liner-compatible outers carry the attachment points, though some riders run Rambo liners under other shells |
What Riders Say
We found an Amigo on sale that was 100 grams and 1200 denier exterior. It's a really nice blanket and compatible with the liners too. Currently I have Dani in her size 72 (100 gram) with liners 100 grams and 300 grams of the same size. Chance is a size 69 and I'll buy a 100 gram liner for him to make his blanket a 200 if ever needed.
We have a 16h1 and the 78" blanket fits him well. He must be a roller because he comes back in from the field with the blanket covered in dirt and mud. Since owning the blanket for the past couple of months, we've had no tears, no wet horse. The blanket has always stayed on well. Now we're using the rain sheet over the heavy blanket as the temperature drops into the 30s. Again, now blanket shifts or tears.
Neck cover, combo neck or the next weight up?
When the neck is the cold or wet spot, add a neck cover or pick a combo neck before you go up a weight; when the horse is cold through the body, go up a weight or add a liner instead. A neck piece keeps rain off the crest and shoulders, but it adds no warmth to the barrel.
Detachable and combo necks are common on heavyweights, from the WeatherBeeta Comfitec Essential Turnout Detach-A-Neck 360G to the Equinavia Thunder360 Detachable Neck Heavy Weight Turnout Blanket 300g. One rider values the fleece inside the neck for saving the mane; another prefers necks that attach with hook-and-loop tabs, which shift and turn less than those held by surcingles.
| What you see | Reach for | Why |
|---|---|---|
| Body is warm but the neck gets wet or wind-blown | Neck cover first | Riders add the neck piece for heavy rain and for windy days, and keep the body weight where it is |
| Temperature falls below about 30°F on a horse already in a medium or heavy | Neck cover on top of that weight | One rider's horse is happier with a neck cover below 30°F, and the weight stays the same |
| Horse is cold through the body, shivering or tucked up | Next weight or a liner | The cold is in the body, not just the neck; a liner or heavier fill adds body warmth, a neck piece does not |
| Horse is full-coated and the cold is dry | Neither yet | The coat is doing the work, and the University of Maine Extension chart adds a hood only at heavyweight plus liner in deep cold |
| The blanket you own has no neck attachment points | A combo or high-neck cut, or the next weight | A neck piece that does not attach properly gaps or shifts |
What Riders Say
This is a heavy well made blanket. I love the fleece inside the neck to help the mane from being rubbed out. I have found every blanket I have bought from this company superior to all the others. Worth every penny!
I dearly love neck covers that attach with velcro, like the Weatherbeeta Detach-A-Neck line (shown on both girls - Foxie is rocking an WB Orican, Bailey a WB Original). They shift and turn less than neck covers that attach with surcingles
Heavyweights with a neck
Combo and detachable necks
Is your horse too hot or too cold in a heavyweight?
Slide a flat hand under the blanket at the shoulder and withers once a day: warm, dry skin means the weight is right, damp hair or steam means too much, and shivering means too little or a wet horse. Check after the warmest part of the day too, because a heavyweight left on through a mild afternoon can leave a horse sweating, and a damp coat chills him overnight.
| What you find | What it means | What to do |
|---|---|---|
| Warm, dry skin under your hand at the shoulder and withers | The weight is about right | Leave it |
| Damp coat, sweat or steam rising at the withers | Too much blanket, or too much for this stretch of the day | Take it off or swap to a lighter weight |
| Shivering, especially if the coat or blanket is wet | Too little, or he is wet and losing heat | Dry him, then add a layer or a heavier weight |
| A blanket still on all day as the weather warms up | The coat cannot fluff back up to insulate | Change down or take it off in the afternoon |
Questions riders ask
Heavyweight turnout blanket FAQ
Is a 300 gram blanket a heavyweight?
Yes. The University of Maine Extension, Rutgers, Horseware and Equinavia all start the heavyweight band at 300 grams of fill, and blankets with 350, 360, 400 or 450 grams sit in the same band.
What is the warmest horse blanket?
The warmest setup is a heavyweight turnout plus a liner and a hood or neck cover: the University of Maine Extension chart calls for all three below 0°F on a full-coated horse and below 15°F on a clipped one. Among single blankets, more grams means more warmth.
Does an unclipped horse need a heavyweight blanket?
Usually not until it gets very cold. The University of Maine Extension chart puts a full-coated horse in a heavyweight from 0 to 14°F and adds a liner and hood below 0°F. Seniors, hard keepers, thin-coated horses and horses new to the cold may need one sooner.
Can I layer a sheet over a heavyweight in rain?
Yes, as long as the sheet fits over the heavyweight without pulling at the shoulders or withers. Some riders add a rain sheet over the heavyweight when wet weather drops into the 30s; check under both layers daily for sweat.
