I travel between Idaho and Illinois, so I'm used to temperatures ranging between -45 and 50 (spring boarding in ID). This jacket will keep you warm in subzero temps if you layer up properly. I was perfectly comfortable just standing around in -7 degrees with this jacket and underarmour, but the loose fit allows for substantial layering. Also, the venting on this jacket allows it to breathe when the temps shoot up, or your working hard building jumps, jibs, setting rails, or hiking the back-country (all of which I've done with this jacket). Just open the vents, loosen the cuffs, open the front zipper and use the velcro and you could run a marathon in it. Overall, it's an amazing jacket and you can't beat the price or the fact that it's volcom. I can't find the pass pocket, though. If anybody finds it, just let me know haha.
