The ALTIOS' hybrid suspension system, composed of a mesh panel and expanded polystyrene liner, makes this helmet extremely lightweight and comfortable to wear. Thanks to this innovative design, the helmet ‘floats' above the head for a near-weightless feeling. The space between the head and the liner allows for effective ventilation with the Climate Control System. Durable ABS shell. This helmet is very ergonomic, adapting to any head shape, and offers two options for attaching a headlamp: a removable ADAPT system-compatible mount, or clips.

Lightweight and comfortable fit, thanks to a hybrid suspension system combining:
- an expanded polystyrene liner for shock absorption
- a comfortable inner mesh liner, which makes the helmet feel weightless on the head
Durable construction: injection molded ABS shell provides protection
Climate Control System: provides ventilation between the inner shell and the top of the head (can be closed in cold weather with the 6 plugs stored in the inner shell)
Removable ADAPT clip, for easy attachment of any Petzl headlamp equipped with the ADAPT system (TIKKA/ZIPKA family)
Removable and washable headband foam and mesh
Easy-to-use molded adjustment wheel quickly dials in the headband size, even while the helmet is being worn
Adjustable chinstrap, nape height and headband for an extremely comfortable fit
Chinstrap can be adjusted forward or backward for added comfort Adjustment buckles are placed to the side, away from the chin
Narrow polyester webbing straps offer improved comfort
Headlamp attachment with 4 optimally placed clips
Compatible with VIZION face shield

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.

I feel naked without it.

Good ventilation
Rides well
Rides a little high
I paid full price for this baby in 2011.

I've had this helmet (in gray, of course) since 2011. I'm a little ashamed to admit it, but I have a pin head. No doubt it's crammed full with a dense and incredibly efficient brain, hence the headaches, but it does create a problem when finding helmets that fit properly.

I really hate looking like an 8 year old girl on a barbie bike with handle bar tassels while a bowling ball that's been chopped in half, painted like a ladybug, and passed off as a helmet sits so far back on her head there is actual danger the chin strap might at any moment constrict her esophagus and cause an untimely death. But that is often the case with One-size-fits-all helmets for me. Don't get me wrong, I'm a proud supporter of girls on bikes, even pink bikes, but loose fitting helmets suck. I say loose instead of poorly fitting because I've never really experienced a helmet that was too tight.

The small size in the Altios fits me pretty damn well. The quick-adjust wheel knob deelie works well with one hand when switching between wearing a hat under the helmet and not. I've used the helmet on rock, ice, and glacier and I have been pleased by it's performance, if sitting in one place all day, attempting to not get noticed can be considered a performance. I haven't taken any major falling objects to the head while wearing this helmet but I have been pretty rough with it and it still looks almost new after 3 years. I wish I could say the same for the fading Justin Bieber stickers. The hybrid suspension system is very comfortable and has allowed for more ventilation than non-suspension helmets. I used the past tense for the ventilation because over time the suspension has relaxed/streched and now sits on the foam. I don't notice this from either a comfort or ventilation stand point but I think it's worth noting. The one other thing I'm not super stoked about on the Altios is the side straps that go around your ears do not have any length adjustment. The chin strap does and that buckle works alright, but I've found that the side straps can end up biting into the bottom of my ear over time. It only happens on one side because of course God thought it would be a good idea to make my ears lop-sided.

Overall I would say I've been very pleased with how the Altios has held up over the years and how it only rarely made its presence known over a long day in the mountains. That being said, it's not the lightest helmet on the market and I think, depending on fit of course, I'm going to be looking to a foam helmet in the future. Something like the BD Vapor or the Petzl Sirocco, but only if they change that heinous color.
