Product details

The Sea to Summit Camp SI Mat is a value-oriented sleeping pad that offers comfort and warmth for backpackers or general campers. The 4.1 R-value and 1.5" thick foam core are a great blend for achieving comfort and durability during three-season use.

Key Features:

  • PillowLock System – Each Sea to Summit sleeping pad is supplied with an adhesive tape to apply in specific positions on the pad's top; This system hooks to a Sea to Summit Aeros pillow (sold separately), creating a complete sleep system that stays connected during the night.
  • Multi-Function Valve – The Camp SI features a dual port valve that pairs with the Airstream Pumpsack. This makes inflation fast and simple while limiting moisture to the pad's interior. Once filled, the micro adjustment allows users to fine-tune the pad's firmness.
  • Abrasion Resistant – A 75 Denier exterior shell fabric increases the pad's longevity and durability.

This self-inflating sleeping pad has an R-value of 4.2 which means it will keep you insulated from the cold ground while you sleep. It's 1.5 inches thick and is available in a variety of sizes! Light enough for backpacking trips as well (the Regular size weighs 1.7 lbs). This sleeping pad also features Sea to Summit's unique PillowLock system which pairs with any of their pillows to securely lock the pillow in place so it doesn't slip around while you're sleeping.

Versatile sleeping pad, with an R rating of 4 (meaning it can keep you warm in very cold weather, but also be a good option for warmer weather hiking). This pad is good at transitioning with the weather - so if you go to sleep and it's in the 50's but the temperature drops to the 20's or 30's by the time you wake up - this pad will keep your sleep system warm and comfortable.
