Basecamp Thermolite BT 4

The Basecamp offers a generously sized, contoured rectangular design to accommodate sleepers who like to stretch out full length or those who like to curl up into a ball. Its also a fantastic solution for those who find a typical sleeping bag too confining or for the restless sleeper who can toss and turn a little more freely. Full length zippers on both sides offer unparalleled ventilation, and even allow the top to be removed for use as a quilt. Plus, the Basecamp series uses clever variable attachment systems to integrate with Sea to Summit's sleeping mats and Aeros pillows perfectly, so you're always comfortable
