Great Jacket
BillO629782324
Great fitting lofted jacket that is superlight. I haven't tried it out because of the intense heat right now, but it is built and cut for cool- cold weather with good ventilation.

Researched in a lab, tested on the trails. This jacket has the tech you need to take on frigid miles—down-filled baffles for warmth and AeroLoft perforations for breathability. Stretchy panels help you move with ease and adjustable details let you dial in your fit. Don't need the warmth? It packs into the pocket for compact storage.

Fits true to size!!!! Great feel to it. Went running out in 32 degree weather and was just fine. Fits slim but the jacket is mostly for a runner’s build so it’s fitted as well (but stretches out in needed areas). There are tiny holes for breathability. I sweat a lot so that helped out for me.
