Why We Like The Salomon MTN Lab Helmet

An ode to those with an affinity for Type II fun, Salomon's MTN Lab Helmet is an ultralight lid that's equally at home slaying pow in the Rockies as it is on gnarly ascents in the Alps. Thanks to the hybrid in-mold design, the MTN Lab has a sleek, low-profile look, with EPS 4D technology that helps absorb oblique and vertical impact.

The MTN Lab is equipped with a breathable, moisture-wicking merino wool lining that stays naturally odor-free even while we're sweating up a storm on an exposed glacier. Passive ventilation comes in handy to keep our heads cool when we're ripping turns through spring corn, and the custom dial fit system lends itself to instant adjustment in case we need to throw an extra layer on when the mercury drops.

An excellent lightweight helmet

This helmet fits me surprisingly well for its intended round head profile (husk prime fits better for my oval head better). That being said, if you're looking at this helmet you're here for a reason and this thing delivers. It is so light and breathes so well you practically forget about it. That being said, it is insulative enough to not have you feeling cold, but helps prevent you from overheating vs typical DH ski helmets. On cold/high wind/ inclement days you will want put your hood up, wear a skullcap, or both. I haven't used the warm weather liner yet or taken it biking or climbing, but for my ski days I am so pumped I picked this helmet over other options. :)

Great ski touring helmet

I've put it through the wringer
Size Bought:

Love the weight, the different levels of insulation so you can swap out depending on the temperature, and feels very solid and good protection not only from the top but also the sides and back. Appreciate the vents for the free air flow as well.

I hate ski helmets, tried them all, they either don’t fit,too hot,can’t hear…… If only they could be like bike helmets- light comfy … all the things Well this one does the trick for me, forgot I had it on. I use it with the summer lining and either a headband, thin or thick beanie or baseball cap. So much more adaptable for piste or tour. As a Mountain Guide I’m pretty intolerant of kit that doesn’t work so really pleased.

MTN Lab and Husk Prime MIPS

Salomon helmets have fit my head perfectly and their fit seems to be consistent among different helmets in their lineup. I also bought the MTN Lab helmet, because I spend so much time touring and in 50/50 days with my wife and kids. I could go with just the MTN Lab helmet for everything. It’s light and comfortable also.

Comfortable ears!

Having slightly prominent ears, I have struggled to find a helmet that doesn’t cause ear pain. I’ve just completed a week’s skiing wearing this helmet and have remained pain free. The combination of the design for round head shape and soft ear covers seems to have done the trick. My son wears hearing aids and has another Salomon helmet that works very well for him too.

Great backcountry helmet

Please provide at least one high visibility colour choice.. ie. yellow, orange. For backcountry safety, having a high visibility colour is important for search and rescue.

Super lightweight backcountry helmet

Recently got this to replace my climbing helmet to have a backcountry ski specific. I love this helmet! It is lightweight, easy to carry and does the trick. Unfortunately my head is 55cm and I wish I had a medium instead of small for a little more wiggle room. Consider sizing up if you are on the fence.

Touring focused, Inbounds capable.

The helmet space is pretty crowded these days. The Mtn Lab is a good lid for someone who prioritizes touring in their skiing, as the permanently open ventilation and swapable liners are better for that kind of rider. If you're mostly inbounds, then there are better options for you that will keep you warmer on the lifts. Maybe you use your climbing helmet when skiing sometimes. But the reality is that climbing helmets, even the newer ones with the "ski mountaineering" certification, don't give you the same side impact protection that an alpine ski helmet offers. Being able to think, reason, recognize your loved ones, and go skiing are all things you could lose if you slam your melon into a tree or accidentally tomahawk through some rocks. The dual certification on this thing is a big reason to consider it. Does it weigh more than your climbing lid? Probably. But save the weight on your feet, not around your brain unless you've got pointy things on your feet and thousands of meters to ascend. I typically ski with a thin hat, ball cap, or balaclava under my helmet, and the MTN Lab in size Medium was right on the money. The adjustable cinch in the back should be standard on every lid. I swapped for the lighter liner immediately, but the ear pads could be nice. The headlamp catches on the sides are very nice, and prevent you from having to tape your lamp to your lid on after-dark exits. Someone in the comments said that this lid doesn't have a good goggle strap in the back, but the one that comes stock is great. Someone else asked for a light way to attach the helmet to their pack, and thankfully this one comes standard with a chin strap that many packs can grab onto. Only used it a few days thus far, so can't comment on durability, but I'm quite satisfied.

Okay protection, low weight, flimsy in places

I bought this helmet last year and have used it whenever I am touring. I feel safe and protected while making conservative decisions in the backcountry, but I would not wear it to ski at a resort. I'm writing this review because I recently broke the very thin plastic adjustment strap for the head, and was hoping to be sent a replacement part. It snaps right out and seems like an easy thing to replace.
