When stopping for a break or relaxing in camp, it's nice to have a dry, comfortable place to sit. The Wilderness Technology Folding Zag Seat Pad is made of closed-cell foam that won't absorb water. It provides a comfortable spot on the ground, rock, or log insulated from moisture and cold. Measuring 15.5 x 10.75 in. (39.4 x 27.3 cm), it folds like an accordion to easily stash in your pack pocket for quick access. Weighs just 0.98 oz (27.8 g), so you'll be glad you brought it along.
