40ozIt holds your water, doesn't leak, it's not that heavy, it's cheap.But don't try to put ice in it and hope it to last more than 2, best case scenario 4 hours in a not that hot 30C day.Also, it sweats, specially from the top. So you shouldn't keep it near paper or a notebook in your backpack.Having said that, it's a okay bottle. And just that.It will somewhat keep your drinks cold, it sweats but hey at least this one doesn't leak!! (So you should clean it regularly and let it breathe something, the water and humidity will cause mold if you don't)
