The Sitka vest weighs 44 ounces. You get a lot of vest for this weight. Most of the weight in vests is the seat cushion. Sitka addressed that by making the cushion thinner, but denser. It seems comfortable, and the vest has the best, easiest adjustability from Small to 2XL that I've seen yet. You can wear it high, or lower it. Personally, I like a vest to ride lower, just my opinion. Field testing this season will let me know if this is it!
