Crag Sender Climbing Helmet
Mammut's Crag Sender Collection consists of climbing gear specialized for modern climbing at sport crags, and the Crag Sender Climbing Helmet is lighter and more performance-oriented than most of Mammut's helmets for all-around climbing. It utilizes a hard shell for lightness and reliable durability, and EPS foam adds impact protection. You can adjust the fit with a dial that's easy to use even while climbing, and there's an adjustable chin strap and additional cushioning to ensure a snug fit.

Comfortable and stylish
Very comfortable helmet for outdoor sport climbing. I like the color and texture more than other helmets I’ve had.

Used twice so far. I have a small head, good fit, light weight.

Great crag helmet
Super comfy, fits my big head but is still adjustable enough to fit friends' heads when necessary. The headlamp clips are also clutch. A little pricy, but worth it if you want a helmet that looks good and doesn't need to be worried about.

Perfect helmet at a fantastic price
Great helmet for all around climbing. Love how adjustable it is, and the multiple included padding sizes was unexpected but a huge bonus. Not only good for protecting from bumps, but it also proved to be a fantastic head pro during a huge hailstorm that chased us off the mountain. “And THATS why we wear helmets!” At flash sale price this was just too good of a deal to pass up. Would recommend and purchase again without question.

This is a very comfortable helmet. I forgot it it was on my head multiple times it was so light. It also looks great in photos. It has a large range in head sizes and shapes and is easily adjusted.

Amazing Value
Super light and comfy, this helmet disappeared on my head. Picked up two of these for me and my climbing partner to use on our first outdoor climbing adventure. We were both very happy with the fit and feel of the helmets. Both the color combinations looked really good in person. No worries having them hanging off the back of our backpacks. Exactly what I needed from a climbing helmet, and from a respected and stylish brand.

It's been a bit since I purchased it, but I did manage to (unfortunately) use this helmet for its intended purpose. It took a rock about half the size of my fist while I was belaying and while its useful life is now done for me, it did exactly what it needed to. RIP, thank you

Climbing Helmet
I use this as my primary climbing helmet and do not particularly love wearing helmets but, I think this one is just fine.
