Thermarest Synergy Lite Coupler

Jump to: Our Verdict / Features / Specifications

A lightweight cover that transforms your sleep system, especially if you are a quilt user.  

Thermarest says

Combine two mattresses for a luxurious, adventure duo-friendly sleeping surface.

Synergy Lite Sheets are designed to wrap your sleeping pad in a lightweight layer of comfort for a great night’s rest. Made ultralight for backpacking and backcountry travel, matching perimeter loops make them ideal for use with Therm-a-Rest backpacking quilts. Along with added comfort, they also protect your sleeping pad from dirt and oils, reducing the need for cleaning and extending the life of your pad. Sewn from premium soft-to-the-touch nylon, Synergy Lite Sheets are machine washable for hassle-free care and available in a range of sizes that fit both rectangular and tapered pads. The coupler size joins two pads together to form one large mattress for backpacking duos.

Our Verdict

A fitted sheet made from silky lightweight nylon, that you place over 2 air mats to transform them into a double mat for couples who like to cosy up in the backcountry, or the soloist who likes to sprawl out. The sheet not only protects your pad from dirt and body oils, which eventually can tarnish your air mat. It also makes for a much nicer material to sleep upon, which is especially more noticeable if you are a quilt user, as you aren’t sleeping on a bare mat.

After your trip, the sheet can simply be put in the washing machine, which is much more convenient than putting your air mat threw the wash.
