Thermarest® NeoAir® X-Therm MAX

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). Oh and if that's not cool enough, it's also incredibly comfortable.

The MAX version is rectangular and gives maximum room for different sleep positions.

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.
