Thermarest NeoAir X-Therm

Cascade Designs

  • The NeoAir® X-Therm™ offers more warmth per gram than any other air mattress in the world. It's the lightest mattress to deliver full "EN rated" warmth for your Zenbivy Bed (or any other EN rated sleeping bag). Gram counters will love the standard tapered shape, but we think it is best with the bed-like rectangular (MAX) shape. It does have that “crinkly sound” as a tradeoff for the low weight, but the Zenbivy Sheet tends to muffle it somewhat. If every gram matters, and you want full “EN-rated” warmth, this the the mattress to get.

Size Guide

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm. If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally. When in doubt, size up.
