Thermarest RidgeRest Deluxe - Large Sleeping Pad:
Thicker than the classic closed-cell RidgeRest®, sleeping pads, the RidgeRest® Deluxe offers excellent warmth for cold weather conditions on the trail and in the mountains. It's the clear solution for four-season backpackers and climbers who want a durable mattress that doesn't require a ton of space. Like the classic RidgeRest®, the RidgeRest® Deluxe features rows of indentations to help trap warmth and hold it close to your sleeping bag. The thicker profile potentially holds heat longer than thinner width mattresses.
