The Comfort Plus SI series combines the comfort of a 3-inch air mattress with the support and self-inflating performance of a foam core - without the expected weight penalties. This is made possible by Sea to Summit's patent pending Delta Core technology, which removes all but the optimal amount of foam without sacrificing support or durability. A luxurious 30D stretch knit fabric is used on top for a soft next-to-skin feeling. Lightweight 30D polyester with extrusion laminated TPU is used on the base.
