Like the original NeoAir, this mattress is very light, reasonably warm & ultra compact, but the NeoAir Trekker is even more comfortable and durable than it's predecessor.

Thermarest say -

"The surprisingly light and compact NeoAir Trekker air mattress offers exceptional comfort and durability for maximum versatility. Our patent-pending Triangular Core Matrix™ technology creates over 100 internal cells to provide ample three-season warmth without the bulk of added insulation, while providing the most stable night's rest of any air mattress made. A rugged polyester bottom boosts all-purpose durability and a supple polyester top is the right choice for those seeking to trim weight, not comfort. Stuff sack included."
