Low-profile Skywalker 3.0 Climbing Helmet with hybrid protection and airy ventilation

What Our Gearhead® Experts Are Saying:


"I’ve guided long days in the Skywalker 3.0 and forget it’s on. The hybrid build takes knocks without adding bulk, the dial fit snugs down fast at the crag, and the fixed vents keep airflow moving on hot approaches. Headlamp clips are bomber for pre-dawn starts."


We strap on the Skywalker 3.0 Climbing Helmet for everything from gym laps to multipitch missions. Its robust hybrid construction blends a tough ABS shell with EPP/EPS foam to manage both daily bumps and serious impacts, while a low-profile shape stays out of the way in chimneys and tight squeezes.


Nine fixed vents keep air circulating as the route steepens, and a rear thumb-dial cinches a precise fit across a wide size range. Headlamp clips lock lights in place for alpine starts, and the included storage bag plus stowable adjustment wheel simplify tossing it into a pack. Light, durable, and headlamp-ready, it’s the reliable lid we trust on every pitch.

Very comfortable helmet, and nice color options. It is a one-size helmet, which means there's a large range for head sizes, which is convenient. My spouse has a large head, and this is the only helmet that can fit him without it hurting on the sides of his head. Other brands L/XL sized helmets are still too tight on his head, and we found this to be the only one that worked well. The downside for me is that I have a smaller head. It still fits well, but I have to tighten it so much, and it leaves an awkward-looking gap from the back of the head to the back of the helmet. This could be solved by having a smaller range of sizing, but then it would defeat the purpose of this being a one-sized product.

Feels Cheap, Fell Apart on Arrival, Pulls Hair

Received product and immediately had the top cushioning come off, they come with extra sticky things to secure it in place but those don't work very well either. Also, now I have to worry about a foam piece coming off whenever I take the helmet off. The design isn't very hair friendly, frequently snags on those hairs that you don't put into a bun due to the sharp plastic edges, making up the vents and other fitting equipment. I would recommend getting the more styrofoamy style helmets, not a fan because it doesn't vent as well as this one. But as long as I don't have to worry about my comfort flying away whenever I take my helmet off I'd count it as a win.

Fantastic climbing helmet

This is the most comfortable helmet I have ever owned. I have a huge noggin and this handles it no problem. Easy to adjust and store. Looks great while wearing and stream lined enough that you do not look like an egg head.

Great fit and price!

Helmets like gloves are a complete crap shoot when it comes to sizing and this one fits great! The one-size-fits-all features a nice boa dial to let you...well, dial it in. You have plenty of room underneath for a beanie or soft cap. Luckily, I have not had to test it!

Great helmet Mammoth

First just a huge fan of Mammoth stuff. Great gear, high quality and has a good look to it. This is a good helmet for climbing, biking, and honestly if you aren't worried about fashion on the jobsite can get away with it on some low key sites. The chin strap gets you points with the safety crew. But note it is not TYPE 2, so no help on that. Just type 1 and EN 12492. All good and Mammoth keep making cool stuff!

The helmet is light and pretty comfortable to wear. I have a big head and the adjustability is nice. Unsure on durability as I haven't used it yet due to canceled trips.
