The success of a sleep system relies heavily on your mattress. If you've ever experienced a cold sleepless night outdoors, you know how quickly it can turn a good trip very bad. The mattress you pair with your sleeping bag should provide you both comfort and warmth. Zenbivy Mattresses are properly insulated with an R-Value of 5+ to match the stated temperature ratings of not only our Beds, but all EN-rated sleeping bags. Stay warm, sleep soundly.

The Flex™ Mattress is perfect for those that want maximum comfort when they set up camp, whether that's in a developed campground or on top of a mountain. The Light Mattress is a great mattress for the avid backpacker that looks for comfort at the lowest possible weight and bulk. The Flex™ 3D Mattress, a luxuriously comfortable 3-inch thick version of our original Flex™ Mattress, is optimized for car camping.
