I'm headed to SE Alaska in August for a deer hunt then again next May for black bear. I'm looking at the First Lite SEAK jacket as a heavy duty option but nobody around me has one I can touch or try on. Is the 3.5 layer similar to a softshell? Or maybe a North Face Apex Bionic jacket? At 24oz I'm assuming it's not a regular laminated jacket like the Boundary Stormtight.
