Mammut

Crag Sender Climbing Helmet

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

Super light and comfortable, you forget that it’s even on.

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.

Breathable, light, safe

A great lightweight helmet that stays cool during hot days. The tightening system is easy to use, very precise, and comfortable. After using the helmet twice a week for 3 months, the internal padding has remained pristine and is showing no wear. However, as with any helmet, I recommend taking it off when applying deet bug spray because the finish on the top of my helmet is starting to peel a bit.

Great all round helmet, I absolutely love the tightening mechanism and it's overall comfort. It's very durable but still light enough to strap to my pack for long technical mountains

Highly recommend for women!

Familiarity:

I've used it once or twice and have initial impressions

Size Bought:

S/m

Purchased the s/m size after measuring my head with a tape measure. I was close to the end of the s/m but below the m/l size and I'm happy I went with the smaller size. I am female with extremely thick, curly hair. I often have trouble with baseball caps, but the helmet fit over my hair without issue. The helmet fits extremely well. It is lightweight, breathable and very comfortable. I wore it in 90+ F° with 50% humidity and barely noticed the helmet, while fellow climbers were dying to get their helmets off. We were also putting up new routes with a bunch of loose rock and the helmet took it well. I personally love the jade color. Super impressed.

Too deep

This helmet is deeper than the wall rider. The shell itself rests on the top of my ears and the adjustment arms didn’t want to stay off the base of my ears. The deep shape also gives it a weird profile on head and felt pretty goofy in it. The brow also would not allow me to wear sunglasses in conjunction with the helmet. On the positive side, it is super comfy other wise and really light considering how much additional shell Mammut added to the foam versus leaving it exposed.

Light and size adjusts well for when I'm just wearing the helmet the crag, or have on hat and hoods while alpine climbing in the winter. I think the best review for a helmet is "I forget that I have it on", which certainly applies here! Highly recommend it!
