The Peregrine Perch Air Sleeping Pad is an extremely simple and effective pad. It balances warmth, weight, durability and bang-for-the-buck to an exceptional degree. The Perch Air Pad was developed as Peregrine's lightest, most durable pad option in the self-inflating pad category while maintaining a robust 3-season rating. With an R-value of 3.2, it is warmer than most UL self-inflating pads on the market, making it a great option for early spring and late fall. A simple, no frills twist valve is positioned at the corner for fine-tuning firmness and air dump. The Peregrine Perch Air Sleeping Pad fits great into a small pack for the minimalist UL backpacker and alpine adventurer.
