Sometimes its a pain in the ass to have a helmet with you but I have never gone without one. I remember being a kid and getting my first ski helmet some weird bright yellow uvex foam thing that I had to squeeze over my abnormally large child head. When bootbacking its hot and regardless of if I am doing a diagonal or a frame ski carry the first generation snowpulse makes it hard to strap down the helmet on the back without it flopping around and its just too hot to have it on going up. Yea sometimes it flops around and smacks me in the back of the head or in the face but when i get up to the top and my buff is all sweaty and the wind is going my noggin is freezing its nice to put the helmet back on and just get warm again. The thing I will say to my head injury story is that its sad to see when you pay a bunch of money for a helmet how shodily they are put together. I know the helmet protected me but getting to the bottom the foam inner shell was separated from the harder PU outer shell. When I pulled the shell out it was literally attached my some hot gun glue smeered around seemingly at random and to be honest was not liberally applied. That pisses me off if one hard impact is enough to break the bond between the shells. How does this affect its ability to protect from a second impact no idea but some chinese dude putting a dab here and a dab there for a 150 dollar helmet is a little lax tbh.
