Big Agnes Boundary Deluxe Insulated Sleeping Pad in Blue, From $108 (was $180) at REI

A quality sleeping pad is the unsung hero of camping trips, whether bushwhacking through the backcountry or chilling at a car camping site. Trying to catch some Zs on the ground is never an easy task, but this 3.5-inch thick pad from Big Agnes will make sure your outdoor slumber is sound, regardless of where you are. The tough bottom is made from a recycled nylon ripstop material while the comfortable top is covered in a cushioned quilted nylon/spandex fabric. Inside, it's constructed with I-beam chambers for weight reduction and stability, while PrimaLoft Silver insulation uses a heat-reflective barrier to better trap body heat. It's also been given an antimicrobial treatment that helps make sure no nasty bacteria will grow on or in the pad. At 1 pound, 9 ounces for the Regular size, it’s not a featherweight, but the 3-plus inches of thickness means it’ll sure be comfy anywhere in the wilderness.

Satisfied customers rave about this sleeping pad's comfort level, saying that “it’s the most comfortable backpacking pad I've ever owned," and that it is the “perfect size and shape.” Shoppers also commented that the pad is great for side sleepers: “I usually sleep on my side…and this is the best pad I’ve ever tried."

Other shoppers loved the warmth that the insulated pad gave them on chilly nights outside. “Slept on it in the upper 30s and low 40s," one shopper said. "Seems to be pretty warm so far.” Another shared that sentiment: “I used it in temperatures in the 30s and it helped a lot with keeping me very warm.” Most shoppers who left reviews agreed, with one enthusiastically summing it up by saying, "Best I've ever slept in a tent, period!”

If you don’t have a quality sleeping pad like this compact and comfortable model , it’s time to upgrade. Not only is it light enough to take on short backpacking trips, but it’s thick and soft enough to make car camping or overlanding trips seem decadent. And, with this one being a solid 40% off, it’s a great buy that will feel even better when you’re sound asleep at your favorite campsite.
