Update: added some extra photos with a measuring tape. Hopefully that helps a bit. I think the torso length might be 21? The padded belt part is 28 inches across. Up for sale is my used ZPacks Arc Blast - it’s been used, but doesn’t smell and has plenty of life left! Please see the two side pocket pictures, they could definitely use a patch 👍🏼 I don’t remember if it’s a small or medium (both torso and belt) but I’m a 5’6” female, 150 lbs for reference (pic of it on me included) Let me know if you’d like more pictures or videos. 💛 First time shopping on Poshmark?
