Insulated Four-Season Shell

A single-wall summer tent loses body heat as fast as you can produce it.

Handles Snow Loading

Wet snow piling on a flat panel overnight collapses poles that held fine in summer.

Condensation Venting

Breath freezes on the inner wall unless vents move that moisture out all night.

Setup With Gloves On

Bare hands last about a minute at ten degrees, so buckles have to be big.

Sleeping Off the Ground

Frozen ground pulls heat out from below, which a raised platform avoids entirely.
