Other Features • smaller die-cut holes in body contact areas -- shoulder, hips, and feet -- keep you warm
• Larger die-cut holes in non-body contact areas reduce the mat's weight and bulk
• Constructed using Delta Core-V techniques to minimize weight and bulk, yet maximize warmth. Using pressure-mapping data to define the contact areas creates a map for the distinct core pattern.
• Patent-pending multi-functional valve. High flow rate for easy inflation; one-way deflation mode prevents re-inflating while packing up and fine-tuning bleed valve for costumized comfort
• Anti-slip silicone print on the top and bottom helps keep your mat in place
• Made with environmentally friendly polyurethane foam that is very lightweight yet still offers excellent memory and self-inflating performance
• Comes with a 3-Denier stuff sack
