Just right for shoulder seasons

I've used it several times
Size Bought:
6' 4"

This jacket is perfect for early mornings and late finishes on shoulder seasons. I've had it for a couple of months now and it's been a permanent resident in my climbing backpack. I'll usually start out approaches with it and then it'll pack away very compactly to the bottom of the pack until I walk out at the end of the day. I'm rarely ever cold on my arms so the hybrid approach was just what I was looking for. Comfortable fit and a high quality build

Prop 65 printed on the label

I wouldn't have purchased had the product information informed me it was made with materials with Prop 65. I know that's probably in most things these days, but still would rather avoid when it's clearly printed on the main product label.... Also, the fit wasn't great because I have a butt. If you have no butt/a flat butt, then you should be fine. Seems warm and compact - wanted to have as my new go-to jacket....
