The Cottonwoods LT Xpore 3L Jacket moves into this generation with a more athletic, articulated fit built around the lightweight, stretch Xpore shell underneath it. No intentionally added PFAS runs through that membrane, keeping the durability the Cottonwoods name has always delivered. This G2 update reworks the pocket layout, swaps in a half-drop hood, and drops the mesh lining from the underarm vents for real airflow at the resort and beyond it. What Our Gearhead(R) Experts Are Saying:"I layer this under my pack straps on the way up and never notice the extra weight, since the Xpore shell packs almost nothing into the equation. That it skips intentionally added PFAS is the kind of detail I bring up unprompted when a friend asks what I'm wearing."
