6.5 oz. decently priced. (compared to icebreaker superfine 190 which is double the price) very very soft next to skin. very thin, breathes, etc. not quite a HOT weather shirt perhaps but an eighties and under type of thing. has little ribs that are very clingy, so watchout. layers wonderfully under a quantum windshirt. regulates temp..cools you, insulates you too. and not smelly!
