Looking for the most comfortable vest out these while still protecting the vitals, like the lower back, kidneys, and lower stomach which a lot of vests miss. I currently use a 661 vest and have been pretty happy with it. It does though fall a little short of the L5 where I broke my back. I bought one of those new EVS SV1 Trail protective snow vests last week. Needless to say it's going back quickly. It looked comfortable from pics but it's the total opposite in real life. Also does not come down far enough on my spine. No kidney or lower stomach protection either.
