I bought this not really thinking it would be that great...incorrect! My main issue when out in the backcountry is overheating. This half jack is super breathable and kept me warm in mid-30s weather (no sweating backcountry hiking even after 1k ft. elevation gain). It’s also perfect if you wear bibs in the backcountry because of the way it’s designed, it has the insulation where your bibs don’t cover, and wind breaking material elsewhere...it’s very well thought out.
Super impressed with how well it performed! Trew definitely knows the Trewth and creates quality gear!!
