Endura Full Face Helmets

Impact Tech and What It Actually Does

The headline technology in Endura full face helmets is Koroyd - those distinctive green honeycomb tubes you'll spot inside the shell. Where traditional EPS foam compresses unpredictably under impact, Koroyd's co-welded tubes crush in a controlled, linear fashion, absorbing energy more consistently across a wider range of impact speeds. Think of it less like hitting a wall and more like hitting a stack of ordered cardboard columns: the collapse is managed, not chaotic. For DH racing and hard enduro mountain biking, that consistency is meaningful.

Paired with MIPS (Multi-Directional Impact Protection System), the helmet also addresses the rotational forces that are often more damaging to the brain than direct linear impacts. The MIPS liner sits independently inside the shell, allowing a small amount of slip on impact to redirect those forces away from your head. It's now standard expectation at this level, and Endura include it without charging a premium for the privilege.

Critically, the MT500 Full Face Helmet carries full ASTM F1952 downhill certified status. That's the benchmark for DH racing globally, and it means the chin bar has been tested to the same standard as the rest of the shell - not just ticked off as an afterthought. If you're racing or pushing serious consequence lines, that certification isn't a box-ticking exercise; it's the reason you can trust the lid.

Getting the Fit Right - Range and Sizing Notes

The Endura MT500 full face helmet uses a micro-adjust dial fit system at the rear - and that's a detail worth flagging, because it's genuinely uncommon in the full face category. Most lids at this level fix you into a single fit position and leave you there. The dial system lets you fine-tune the fit one-handed, which is useful mid-ride if you've been sweating hard and the liner has shifted slightly. Small thing. Makes a real difference over a long day.

Sizing is where you want to be careful. The Koroyd core has less give than conventional EPS foam, so the fit profile is firmer and less forgiving of borderline sizing. If you're hovering between a medium and a large based on your usual helmet size, measure your head circumference properly before ordering - use a soft tape measure around the widest point of your head, roughly 2.5cm above your eyebrows. Don't guess. A Koroyd-cored lid that's slightly too tight isn't something a few rides will break in; it'll stay tight.

The MT500 also tends to suit riders with a neutral to slightly oval head shape rather than very round profiles. If you've found other full face helmets pinch at the temples, it's worth checking the return policy before committing. The micro-adjust fit system handles circumference well, but it won't reshape the shell.

Ventilation, Goggle Compatibility, and Looking After Your Lid

This is where the MT500 Full Face earns its reputation. The venting channels are large and well-positioned - channelling airflow front to back rather than just punching holes in the shell and calling it done. On a steep, humid climb in the Brecon Beacons or grinding up a fire road in the Tweed Valley with full kit on, you'll notice the difference compared to a traditional gravity lid. It's not a trail helmet, but it's a long way from the sauna-on-your-head experience of older DH-certified designs.

Goggle integration is clean and functional. The brow cut is shaped to accept most standard MTB goggles without a gap at the top, which matters on wet Welsh winter days when you need eye protection and not a stripe of cold rain down your forehead. The visor is adjustable, which lets you clear sight lines depending on light conditions - a practical touch that gets used rather than ignored.

Care is straightforward. The fast-wicking antibacterial padding is fully removable - pop it out after a muddy session, hand wash in cool water with a mild detergent, and let it air dry away from direct heat. Don't machine wash it; the antibacterial treatment degrades faster with hot water and spin cycles. Doing this every few rides keeps the liner fresh and extends its life considerably. If you've ever peeled the pads out of an old lid after a wet winter season, you'll know why staying on top of it matters.

Pair the lid with Endura body armour for full gravity protection, and if you're building out a complete kit, Endura MTB baggy shorts and Endura jerseys are worth adding to the comparison.
