Mammut

Crag Sender Climbing Helmet

Favorite Helmet!

Super lightweight but still gives plenty of protection. Fits like a glove, is low profile, while still covering lots of surface area!

lightweight, comfortable,and easy to adjust. great helmet.

This is light weight, sturdy, and even looks good. It fits perfectly into most climbing packs or hiking packs with an external carry pocket. There was some worry about the straps being a little thinner but they are sturdy and do not twist when using. I am a beginner climber but based on the other impact activities I do I would say this helmet works for all levels.

Perfect Lightweight Climbing Helmet

The Mammut Crag Sender helmet is a clear upgrade over my BD Half Dome, offering a lighter, more comfortable fit. It's much more breathable, and so far, there have been no durability issues, though I do handle it more carefully than the BD helmet.

Good fit

Fits perfectly in the head being stable even when you bump your head in parts of the wall or roofs

Love this helmet!

Finally used this today. Wore it all day long and didn’t realize it was on most of the time. Super comfortable. Fit really well. And was super light! I appreciate that the plastic shell covers the entire helmet unlike some of the other higher end helmets that lack the abs plastic on the sides in order to save weight.

Excellent helmet

Light and agile. Decent suspension system for head fitment, slightly small fitment dial at the back but you shouldn't need to dial it much unless switching with friends. Easy-fit neck strap dials in quickly.

Great lightweight helmet!

This helmet is an excellent upgrade from an older hard plastic model I had from a different brand. It's lightweight and fits much better. My previous helmet wobbled on my head and didn't protect the front of my skull but this one fits great!

Great Fit

It fits great & I love the color! It came with extra padding to switch out. However, I wish it came with 2 different thickness of padding. I would love a little more padding on the crown. But other than that it is a great helmet.

Comfortable. Light. Excellently priced.

I have used a number of helmets over the years for work and for personal ventures. I currently own a BD Vision helmet as well. I prefer this helmet greatly. Despite the BD having a partial shell and this helmet has a full shell (although this), the Sender is lighter than the Vision. I have ALWAYS favored dial suspension adjustment systems over sliders. Sliders give my OCD a meltdown and they can “poke” you if uneven. This is probably the best dial I’ve encountered. The older Petzl ones were notorious for pulling your hair when they would get caught in the teeth. This dial on the Sender is enclosed and does not do this. Additionally, it’s a fine tooth dial which can get pretty granular all while adjusting EVENLY. When it comes to padding, this lid came with an extra set (free of charge) to replace the initial padding once it’s too far gone. The cherry on top, the inner foam has a circular cutout to accommodate the DESPICABLE HEADACHE CAUSING BALL atop your ballcap. Zero pain. Wonderful. 10/10. Mammut reins supreme, yet again.
