Expensive

I have a small head, but I'm in the size range given by Petzl. I couldn't get the strap to fit properly because it isn't fully adjustable. Once I managed to figure out I could shorten it by improvising (wrapped it around the plastic thing at the back) the fit was alright. Another issue is that there are large gaps between the sides of my head and the helmet. I'm not sure what the consequences are in case of an accident. Lastly, the top of my head sometimes gets hot and itchy, which I think is due to a lack of ventilation in that area. I have the white model which makes me look too much like a mushroom. Keep in mind these foam helmets can only take one impact, so they're not ideal for ice climbing and mountaineering. Another potential issue is that a British mountaineering organization rated the impact forces much higher on this helmet compared to traditional designs.

After using some Ange S biners successfully on my ice tool leashes while wearing gloves, I knew which quickdraws I wanted on my rack. I already have a set of DMM Shield wire gate notchless 18 cm draws (similar to Wild Country Heliums), so I only bought a few 17 cm Petzls to augment my rack (and to satisfy my gear lust.) Compared to the DMMs the Petzls are lighter, slightly easier to clip due to lower gate tension, quieter when they jingle on the harness, nicer looking, but more expensive. I'm a guy with perhaps slightly below average sized hands. and don't find the biners too small. I do recommend you try them in-store before ordering a whole set (which you can't return.) Petzl compromised on the strength (kN) of the biners to achieve the low weight, but this doesn't worry me enough not to buy and use them.
