For 2014, Eureka! introduces the new Singlis Ultralight. The Singlis UL utilizes lightweight fabrics and TPU films for a ~40% weight savings compared to the current Singlis ST model. Weighing in at a mere 15oz, the Singlis UL’s combination of a 20D polyester micro ripstop top fabric and a 75D polyester bottom fabric result in a ultra-light, yet durable, mattress for backpackers. The integrated pump allows for quick, convenient inflation.
