Arc'teryx Cerium LT Men's Hooded Down Jacket in size Large, Color: Black . Cerium LT is ultra-lightweight and packable, with super-warm 850 down fill. The jacket has a “trim” fit so it doesn’t add extra bulk as a mid-layer. I used this jacket maybe once or twice a year as a mid-layer on the coldest of days. Jacket is also ideal to have in the pack for relaxing in the evening around camp. The only defect is a small repair (tiny patch following a snag on the fabric) made next to the zipper - to the left of the Arc’teryx logo (see photo). Aside from this small cosmetic item, jacket is in EXCELLENT condition. All zippers work perfectly.
