Green Montbell Tachyon is vintage 2012 but is essentially unused. I tried it on back then but need an extra large. Comes with original micro stuff sack. 2.6 oz. $50 including shipping.
Dark Blue Patagonia Houdini is in very good used condition. No holes, tears or stains. This came to me via a lost and found so I don’t know how old it is. I still need an extra large. 4.1 oz iirc. $30 including shipping.
