Vector Helmet is rated 4.6 out of 5 by 39.
Rated 3 out of 5 by from fits a very round head I hate climbing helmets, but I am trying to find one I like so I will wear it. My quest continues. The fit is for a Asian round head (I have several Asian friends). Or maybe Charlie Brown. It doesn't fit your typical oval anglo head very well. I bought the m/l. When I size it to fit the length of my head, there are big gaps on the sides. It doesn't fit nearly as well as say my Giro mountain bike helmet or my Smith Ski helmet. Fits more like a Bell mountain bike helmet. It is very light weight and does have a nice mountain bike helmet adjustment on the back. I like that it will hold a head lamp. I just don't have a Charlie Brown head...

Rated 5 out of 5 by from Lightweight Beauty I don't like wearing helmets. They add extra weight, restrict movement, and make my egg-shaped head look goofy(er). But Vector helmet was a game changer for me. Really light, yet still sturdy, it packs very nicely with the new tack-away system. The straps are narrow and adjust really well. Good ventilation system and lightness of the helmet make it super comfortable in warm Californian climate. Yes, dents and scratches are very apparent but they don't seem to compromise the durability of the helmet (and add some character). Bright orange color provides some hotness to the overall look but... does not help with the shape of my head (oh, well).

Rated 4 out of 5 by from Great helmet! The Vector is a great helmet - I tried it out with a quick run up Yellow Spur in Eldo in howling wind on a sunny Saturday. The shape is solid, fits even my small diameter head snugly, with no sloppy moving around as you look up, down and sideways for gear. It was light enough and fit well enough that I forgot I had it on, and that is the most important thing for a helmet other than the safety benefits. All in all, great product. One small request for improvement - the padding on the forehead was fairly scratchy, either due to extra Velcro or maybe the thread where it was sewn. It was minor, and I'll find a fix for that soon.

Rated 5 out of 5 by from Light and breathable The first time I used this helmet I put a dent in the top. I was trying to put it in the top of my bag and pushed down on it a bit too hard I guess.... This helmet is lightweight, and breathable. It also works! I took a large rock to the helmet and the helmet protected me. I bought a second one due to excessive shell damage after that. I like using this a lot. I will say that the profile is a bit bigger than I would like and it frequently gets in the way when I am climbing. It also looks goofy in some pictures ;) All-in-all this is the best helmet I have ever owned, but I am still searching for my perfect helmet.

Rated 4 out of 5 by from Good fit, quality construction I bought this helmet for backcountry skiing / climbing. While not a skiing helmet, this is much lighter and easier to pack in a day pack and it is cooler than an alpine style helmet. Being that backcountry skiing is a much more aerobic activity than lift served skiing regular alpine helmets are just too warm for me. So far this helmet meets the intent perfectly and will provide more protection for my melon than all those times that I left the ski helmet in the truck because it was too hard to pack.

Rated 4 out of 5 by from Great Light Helmet I replaced my previous Petzl helmet with the vector and I am truly enjoying it. I do a lot of single, multi pitch and mountaneering and couldn't be happier with this helmet. It is really light and fits easily in my 35L pack. The headlamp buckles are perfect and properly positioned. The feature I like theb est however is how easy I can adjust the sizing on it. Now I don't have to fuss with my helpmet when I decide to take my beanie off or put it on. The fact that the design is very nice is a plus!

Rated 4 out of 5 by from Light and Large I have a big old noggin. That is the primary reason I bought this helmet. My head is a full 24 inches in circumference. Most other helmets only go to 24 or 24.5. With a beanie on I need something larger and this fit the bill. I also really like how light it is, the less weight the better right? The adjustment system is adequate, but I wish it had the wheel you can turn to adjust rather than the adjustment on this helmet. It requires 2 hands to adjust and is not as easy as a wheel with gloves on.

Rated 5 out of 5 by from Great! This helmet is amazing, especially for people with enormous heads. This and the Vapor are the only helmets on the market right now that comfortably fit my 63 cm head with a lightweight beanie (though I need to remove the forehead padding). On top of that, its adjustability is simple and quick and you barely feel it on your head. Yes, the Vapor is lighter but it's also less durable. This is probably the sweet spot. Although you still need to baby it a little bit.
