TARPTENT Rainbow (Silpoly)TARPTENT Rainbow (new Silpoly version) is a solo version of Tarptent's most popular shelter, the Double Rainbow. This solo shelter includes the same features as double and has more usable space in comparison with any solo shelter on the market, therefore is ideal for people who want a light tent with a large living space. The Rainbow is easy to set up, can be converted to freestanding with trekking poles, and can fit two standard width sleeping pads.
