Sea to Summit's Comfort Plus sleeping mats with their dual layer construction provide the most effective system for fine-tuning the level of comfort available in any air mattress today. The two independent high-resolution cell layers give excellent support by distributing your body weight and shape over more cells. The two layers are also offset for more uniform insulation and cushioning. Because the two layers can be pressurized independently, the top layer can be inflated to your personal comfort, while maintaining a high-pressure base layer for protection from rough or uneven terrain. Both layers can be adjusted independently using the fine tune valve to get just the right level of softness and support. All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.
