Concept prototype · Tack of the Day
What should I wear?
Riders work far harder than the sport gets credit for — a canter sits at 7.3 MET, the same metabolic zone as a jog, with heart rates over jumps hitting 188. So the problem was never that you don't make heat. It's that you make a lot of it, sweat into your layers, then stop dead — and the heat you do have is in all the wrong places.
So stop guessing at it. Set the temperature and what you're doing below, and this Tack of the Day layering tool gives you your own head-to-toe plan — the order it goes on, what comes off when, and where to find each piece.
Working model — numbers are for feel, not finalConditions
set itDamp air doesn’t soak you — it stops your sweat evaporating, so you never dry out. Applies indoors too.
Properly cold
Too cold to ride
Below about 20°F there's nothing you can wear that makes riding comfortable, and it's hard on your horse's airway too. Do the chores, skip the school.
Where you land
The whole day
85 minutes · only 45 on the horseA lesson visit runs about eighty-five minutes, and only forty-five of them are on the horse. Output peaks at jogging intensity, then collapses — and the two ground blocks either side are not equivalent. The first is dry. The last is twenty minutes of fiddly work in a soaked base layer, at the coldest you will be all day. That asymmetry is why the tool returns a stack with a peel order rather than a single outfit.
From cool-down onward you are damp. Everything after that point is spent in clothing that is already wet — which is why drying on the body matters more than insulation, and why the piece has to still be wearable at the school gate three hours later.
Riders are athletes
MET · metabolic equivalentA MET (Metabolic Equivalent of Task) is a multiple of what your body burns sitting quietly — 1 is rest, 7 is working seven times as hard. The CDC calls anything at 6.0 or above vigorous intensity. These figures come from the Compendium of Physical Activities, the same reference sports science uses for every other sport on this chart.
A canter outranks jogging, lap swimming and cycling, and clears the vigorous threshold outright. Mucking out beats a round of golf. The plain-language test for vigorous intensity is that you can't say more than a few words without stopping for breath — which is every rider who has tried to hold a conversation at the canter. This is why the layering question is a real one: you are dressing an athlete who then has to stand still in a cold aisle and go pick the children up.
How it works & what's still open
Activity is the rider's "clipped or unclipped"
Offsets are anchored to published MET values — about +2°F per MET above standing. Run that formula on running itself and it returns +17°, which matches the documented 15–20° rule. Same physics, different animal.
Riders are not passengers
Walk 3.8 MET, trot 5.5, canter 7.3 — a canter is jogging. Jumping hits 75% of VO₂ max and 136–188 bpm. Stable work burns as much as a leisurely ride. Any model that treats a rider as stationary is wrong before it starts.
The glove doesn’t fail — the glove comes off
Seat and inner leg are pressed against a 1,000-lb animal at 100°F, and your legs are working. Your hands are still, holding the reins in a more or less fixed position, in the air movement the horse generates. But review found the failure is behavioural, not thermal: a working trainer loses one glove and goes most of winter without, and takes them off dozens of times a day for buckles. The open question is a sourcing one — warm hand, fingers free.
Same bands as the blanket calculator
One temperature reading, two answers: dress the horse, dress the rider. Same morning, two baskets — a matched pair rather than two unrelated widgets.
Mounted gets a short coat. Ground gets the long one.
Long coats bunch in the saddle. So the activity input doesn't just shift the number — it changes which outerwear category we show. Two sales lanes from one temperature. Confirmed in review, along with why the long coat is bought a size up: it goes over the whole stack.
The mid layer must clear a helmet
A hoodie fails as a riding layer — the hood slips forward under the helmet and wrecks the hairnet underneath. So the mid layer is a zip or quarter-zip, specifically so it comes off over the helmet without disturbing the one thing you can’t quickly re-fit. No general-audience layering guide contains this.
Two pairs of boots, not one
Tall thermal boots for standing on the ground, zipped off and swapped for real riding boots to get on. Thermal riding boots look like the obvious product and are the wrong answer — they dull the leg, and they aren’t what a professional wears in the ring.
Where most winter schooling actually happens
An indoor takes wind, rain and snow off the table — so the tool stops subtracting for them. But it never warms up either: no sun on your back, and it holds the night's cold all day. Spared the weather, not the cold.
Rain wets you. Damp air won't let you dry.
They were one control and shouldn't have been. Falling weather is graded — snow brushes off, rain soaks through — and drives the waterproof shell. Damp air is a different failure: it stops sweat evaporating, so it lands on the base layer instead, and it's the one weather input that still applies inside an arena.
Two garments are called a vest
The layering vest is insulation and sits under Outerwear — the category page is literally titled "Riding Jackets, Vests". The safety vest is a body protector or air vest and is shelved with Helmets under rider gear. They are unrelated products at unrelated price points. This model's hero garment is the layering vest, and pointing it at Safety Vests would send a rider looking for warmth to a piece of protective equipment.
The warm bands aren't dead — they're September, April, and Florida
The cold season opens with the first sharp mornings in September and runs out into April — eight months, not three. So 50–60° isn't a thin band to trim: it's both shoulders of the season, where the swing between a cold start and a warm afternoon is widest and a peelable stack matters most. It is also Florida and the west coast for the whole winter. Same tool, very different customers.
Legs stack like the torso after all
Under-breech layers, fleece breeches and waterproof thermal breeches give the leg a true base / insulation / shell stack. That's why Wet changes the outfit and not just the number — in a saddle your legs meet the weather first.
The neck is covered
Neck warmers close the last empty cell, so every band now returns a full head-to-toe answer. Worth merchandising hard: major heat-loss zone, low price point, and a natural attach to a jacket or vest sale.
Winter = Yes is the tool
The tag already spans the categories, so it isn't just a boot filter — it's the whole winter universe. The calculator becomes a front door onto a set that already exists in the catalog, which means it can pull live rather than being hand-curated and going stale.
