Like a miniature ProLite mattress, the Lite Seat is the ideal companion for fast and light journeys, or anywhere space is at a premium. It rolls up small enough to carry in your pocket and can be carried inflated, inside of ultralight, frameless daypacks for added support, comfort and versatility on your next adrenaline adventure.   Features Self-inflating: Easily adjust the firmness of your seat at camp or on the trail. Packable: Updated closure bungee keeps your seat rolled up tight in your pack. Lightweight: Featherweight makes a minimal impact on your pack weight. Comfortable: Offers plenty of warmth and comfort with 1.5 in (3.8 cm) thick foam.
