The Summit 25/38 is the standard against which all other self-inflating expedition mats are compared – and it remains pretty much the first choice of most expeditions. Its 40 denier “rip-stop” upper and water-repellent top fabric with 70D Non-slip coated waterproof base fabric gives it durability and the vertically and horizontally drilled top-quality foam core ensures it continues to fully inflate through the large serviceable valve time after time.
Its unique wedge-shaped profile is designed to reduce unnecessary weight - it still weighs less than a bag of sugar – yet it has a special warm zone in the torso area with extra thickness and extra TOG value. It even features an anti-bacterial ether TPU membrane for an air-tight seal that’s been specially formulated to work at lower temperatures. If you’re heading for extreme conditions you can depend on your Summit 25/38, the self-inflating expedition mat of choice for professionals.
The embodiment of their motto, this self-inflating, 5 season sleeping mat is indeed designed for comfort and a good night's sleep when the conditions are adversarial. With a wedge shape design, the Summit 25/38 keeps the warmth where you need it, under the torso, where the foam is thicker and undrilled. Meanwhile, at the head and the toe, the foam has been drilled both vertically and horizontally, to give a lighter end weight. To this end, the fabric weight is 40D on the upper, and a non-slip 70D on the base, making it both tough and reasonably lightweight.
