El Cap



My vote: None ( 3.8 avg )


The climbing helmet with style - the El Cap's stylish design leaves no excuse for not wearing a helmet when climbing. With its visor and narrow design, the El Cap creates a completely new look. In technical terms, the hybrid helmet consists of a robust outer shell combined with an innovative 2K-EPS core (two styrofoam layers of different thicknesses are combined in the Conehead method) to ensure maximum absorption and the highest possible safety. The many ventilation openings and perfect fit make it extremely comfortable to wear.

Quick Adjust

Quick Adjust refers to the straps of the helmet. Do you want the ability to ability to "quickly" adjust the fit. This could be a dial, or other plastic pieces.

Really, most climbers don't need to change the fit of the helmet often, unless you're climbing with and without hats, or you have big hair that flattens and then requires tightening after climbing for awhile.

The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.

To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.

El Cap Helmet Review

Large head small strap

Looks cool, probably will protect my head
Short chin straps
I’ve used it a bunch

Bought the large size (56-61cm); excellent head fit but the f-ing chin strap is short. My head is on the smaller end of this sizing the chin straps are nearly preventing me from speaking; thus I cannot wear a bennie with this helmet even with it completely extended out.

My Outdoors Gear Review no rating given just a review

The El Cap is comfortable, reasonably weighted and robust. I went on a mountain bike demo afternoon and used it as my head protection. Initially I had to confess to a group of mountain bikers I didn’t own a cycle helmet then explain I had brought a climbing one. When I put it on I didn’t get any stick, it actually received good comments on its styling.

The El Cap has done what it’s supposed to, it protected my head from falling debris and when I clattered it on a small overhang. It also helped when I came off the bike and I bounced off the ground.

All in all it performs very well in and out of its environment. And I would recommend it to winter, sport and trad climbers.

UK Climbing Gear Review no rating given just a review

So, is it possible to draw conclusions on these helmets in the light of the earlier discussion? All are fine, but understanding now more about how the design of helmets has to follow the testing standards, I'm less convinced that hybrids are the all-rounder's answer. The El Cap is decent lid and its little peak just makes it look different and cool. I will be wearing it this winter for ice climbing. But now understanding the lack of protection around brim inherent in (almost all) hybrid designs, the idea of taking a swinging leader fall - on bolts or trad gear - is less appealing in such helmets. I spend three quarters of my year rock climbing, and I'm going to carry on wearing a foam lid when I do. The Rock Lite sent to me to review now has a bunch of scratches on its over my right temple from last weekend. I'm not sure if they got there whilst I was chicken wing-grovelling up a local offwidth, or when I missed the crux foothold that should have allowed me to escape its evil clutches and instead pin-balled 10 foot back down the bomb-bay chimney at the back of which this cruel crack lurks. Bruised and exhausted, this drove home the point that having a centimetre of foam between the side of my skull and the rock is preferable to just a couple of millimetres of hard plastic. Of the foam lids, I liked the Edelrid best, in part because of the Germanic engineering of its back cradle, but mainly just because it fitted me well. The Grivel is great to wear, super low profile, wonderfully light and very well ventilated, but its design is showing its age: I think the strapping and size adjustment could be refined, as could it's torch clips. The Rock Lite doesn't fit my head perfectly, but if it fits you there's not much to dislike about it. It has already done its job for me in leader fall and you can't ask more of a helmet than that.

Climbing Gear Review

Love it or hate it, climbing is getting steezier. From neon clothing to reflective sunglasses, flash is back. So when climbing helmets needed a makeover, Mammut introduced the El Cap, which breaks away from the standard bucket helmet with a narrower design and a low-profile visor. At first glance, this helmet looks more apt for kayaking or snowboarding, but the El Cap more than holds its own on rock. With 12 ventilation openings, adjustable headband, and relatively light weight (12 oz.), this is a well-built helmet that looks good. (It comes in two sizes for pinheads and brainiacs.) “The hat stayed on tight even during big whips,” reports our tester, “and the visor kept the sun out of my eyes. It’s not as light as some helmets on the market, but I’m psyched on it. I can’t wait for one with built-in headphones.” We’re not sure the UIAA would approve, but it’s probably coming.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
