I'm thinking of running the StrongFleece 260 under this and calling it good for AZ hunts around 25-45. Keep a puffy in my bag for super cold windy glassing stands and that's it.Well I wore it this morning in 52 degrees,10mph wind & pouring rain doing my morning routine at work. First off the jacket is super comfortable & the new DWR is frickin amazing. I had it over just a t-shirt & it felt plenty warm enough in that temperature. Wind blocking seemed on par with the peloton 240 I had. With a couple layers underneath it would be an adequate piece blocking wind. The water runs off like Teflon & after shaking off the beads of water the fabric seamed dry although I don’t think that would be the case in all day rain. For a T-shower it would keep you dry for sure & I think the fabric will dry super fast. I’ve heard knocks on soft shells for backpack hunts but I’m not so sure I would leave this piece at home. Love it so far & report back after chasing blacktails this weekend.
