The Trauma Void Edit
Which Trauma Void helmet fits your head shape
EQ3 NEOZ & EQ3 Micromocca
Trauma Void EQ3 helmets: the NEOZ with a one-hand buckle
The EQ3 NEOZ is the Trauma Void our riders buy most. It pairs a clean, minimalist shell with Mips, a magnetic buckle you can do up with one hand and an adjustment wheel at the back for a custom fit.
Inside is a removable Coolmax liner that wicks moisture and washes clean. Trauma Void lists the NEOZ as SEI certified to ASTM F1163-23.
The EQ3 Micromocca has a microfiber outer shell with silver-colored glitter piping. Back on Track lists it to CE VG1 01.040 2014-12.

More comfortable for my oval shape head than Trauma void lynx.
Verified buyer · MA Trauma Void Pardus Smooth Helmet
★★★★★
This helmet comes with two liners, a regular and an oval, and it fits me quite well with the provided oval liner. The glitter looks so much better in person than it does in pictures. I get so many compliments on it.

About the Brand
Trauma Void, the riding helmet line from Back on Track
Trauma Void is the riding helmet line from Back on Track, the Swedish company best known for Welltex horse and rider gear. Back on Track says every one of its helmets is fitted with Mips.
The range covers different head shapes: the EQ3 NEOZ, the slim Pardus for long oval heads, the round-fit Lynx and the Lynx Eventing Skull. Riders with long oval heads tell us the Pardus is the comfortable one, and riders in a Lynx tell us they would hate to see it go.
