Camp SI Mat - Regular
- Looking for an affordable self-inflating pad? The Sea to Summit Camp SI mat is a 1.5 in. thick foam mattress with Delta Core vertical coring that lowers the weight and minimizes packed size.
- Delta core technology removes 40% of the initial volume of the polyurethane foam core for minimal packed weight and size
- Delta core technology keeps the bottom surface of the polyurethane foam completely intact which ensures consistent warmth along the full length of the mattress
- One-way inflation valve can be reversed and used to prevent air from being drawn back in; allowing you to roll the mat without fighting re-inflation as you go
- R-value equals 4.0, delivering a great warmth-to-weight ratio; most sleeping pads we sell range in R-value from 1.0 (minimally insulated) to 9.5 (well insulated)
