When bombproof and maintenance-free are the name of the game, reach for the Twentymile UL sleeping pad. Built from closed-cell PE foam, and coming in at a weight that the minimalist thru-hiker can sink their teeth into, the Twentymile UL may be no-frills, but it has everything you need for sleeping in the dirt. Durable and never prone to leaking, these pads are also a great option for outfitters, rental fleets, and anyone who needs their sleeping pad to simply work.
