Size S. Synthetic insulation (Coreloft 65) with good warm-when-wet performance. Designed to layer w/ hard shell bib or pants. I love the boot cut cuffs so this layer sits snug against your leg just above your ski/ snowboard boot, no bunching. I am selling because I let myself go this year (hehe) and my butt no longer fits in a size S. I only used this for one season, approx 10 days. I already bought my replacement size bc this is the best insulation layer I’ve ever found for those cold days. For reference when I used the S I was 125 pounds and 5’6” and wore it over my wool base layer. The MSRP is $199 and you might find online a price of ~$150, however Arc’teryx stopped making this item and stock is low everywhere. I haven’t seen stock in this size at that lower price (FYI). See asking price, but send your offer my way. Will ship anywhere in US. See below websites for more details/reviews. Some reviews have good sizing comments. https://www.powder7.com/Arcteryx-Womens-Axina-Knicker-Baselayer/sale?utm_source=feed&utm_medium=free https://www.evo.com/outlet/long-underwear-bottoms/arcteryx-axina-knicker-pants-womens https://www.altitude-sports.com/products/arcteryx-womens-axina-knicker-llll-arc-18352
