Item # DAK00O9

Ride like the hounds of hell are chasing you.

You're a hard-charging trail rider who dabbles in enduro, you say? Then feast your descent-shredding but pedal-ready eyes on the Dakine Hellion Knee Pads, a pair of flexible and low-profile foam sleeves that serve up impact and abrasion protection without impeding your pedaling. The secret is AriaprenePro foam, a light (just a single millimeter thick), stretchy, and bomber material that provides protection to rival thicker traditional foams without nearly the same bulk or weight. AriaprenePro is layered over, above, and below the kneecap, while thin foam pads on the medial and lateral sides of your knee provide soft tissue and tendon protection. The build is reinforced with aramid fiber to save your skin from getting cheese-gratered when you lay your bike down on loose trails.

Fit is as important as protection, especially if you're planning on pedaling, so Dakine designed the Hellion with an ergonomic pre-curved fit, Cross-X elastic compression straps in the back, silicon gripper elastic edges, and a hook-and-loop thigh strap to keep your pads in place. The four-way-stretch mesh back panel hugs your leg without pinching and improves breathability, and the Hellion's Polygiene odor-resistant treatment helps it stay fresh, so your knee pits don't smell like roadkill after half a season of shredding.

How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.

No More Whacked 'Caps

  • Familiarity: I've put it through the wringer

I went with the Hellions over the Slayers because I figured a little extra protection on the side of my knee caps wouldn't hurt (literally?) and the top strap seemed like a good idea incase they happened to stretch. Definitely not disappointed at all with my decision. The padding isn't too bulky but works like a charm (I'm pretty good at wiping out). I also think it's pretty cool how the pads are flexible yet hard on an impact. Unfortunately they do slide down while I'm riding but never to the point where they fall over my knee and it's only when I'm riding in really hot/humid weather so we'll see if that still happens in the fall/winter temperatures. They are still holding up after multiple wipeouts and they were easy to hand wash. I was in between sizes S and M and ended up keeping the size M (which may explain some of the sliding down as well).
My boyfriend was pretty jealous so I bought him a pair (size L) to replace his old plastic kneepads and he thinks they're pretty rad too! ;)
