TrailblazerGirl is very happy with the new H2O LITE 1L. by GSI Outdoors. It’s super lightweight and convenient for those hikes when you definitely need to carry water but want to minimize the weight and bulk of a typical water bottle. It comes in 3 colors with a lid that doesn’t leak, a rewritable date bar on front and rear to record your name and fill date, and graduations printed on the bottle so you can keep track of how much you’ve had to drink. They’ve thought of everything!
