  • Regular price $328.95

The new Comfort Plus XT Insulated Air Sleeping Mat is the perfect mattress for campers who need an insulated sleeping mat that packs down relatively small but inflates to provide a really comfortable sleeping surface with plenty of room for even the most active sleepers.

Two layers of XT Air-Sprung Cells give you unparalleled support (the lower level can be firm for protection against the uneven ground, the upper level fine-tuned to your personal comfort preference) plus redundancy in case of damage to one layer.

The uprated 30D / 40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability.
