Gear Review: Klean Kanteen Wide Insulated

This thermos converts into an insulated mug whenever you're ready for a warm drink.

Packing dilemma #1,476: Bring a thermos or skip it? Enter this BPA-free vessel, which adapts from insulated mug to thermos with a simple change of lids.

Screw on the leakproof thermos top and pack it away, worry-free. In camp, attach the sipper lid and savor your hot drink. The bottle is double-walled, so your tea stays hot for hours. $23-$28; 3 sizes; 10.1 oz. (16 oz.);
