Amazing Service

Because you deserve it.

Insulated with lightweight, compressible hydrophobic down, the innovative Therm-a-Rest Boost 650 20 Degree bag offers unparalleled customizable comfort for 3-season backpacking by converting from a roomy semi-rectangular bag to a cozy mummy bag with a single zip!

Description

Weather-resistant construction offers all-condition performance: The bag employs 650-fill down insulation for its impressive warmth-to-weight ratio and a hydrophobic treatment allows it to retain its insulating ability even in wet or damp conditions, avoiding the pitfalls of traditional untreated down. The placement of the insulation is strategically "zoned" to effectively balance weight and ensure heat efficiency. Lightweight recycled nylon ripstop shell and lining fabric also helps to protect insulation from moisture.
Adaptable design with a broad fit range: The Boost has a centered zipper that lets you pick the shape you prefer and regulate warmth depending on current temperatures. The semi-rectangular configuration gives you room to spread out while the mummy configuration draws insulation close to maximize warmth. Integrated zippered arm holes let you operate the center zip without having to get out of the bag and also provides hands free use at the campsite while you stay snug inside the bag! The bag is available in a broad range of lengths and widths (see size suggestions below) to accommodate any backpacker or camper.
A multitude of other performance features: A cinchable, insulated hood, a draft tube behind the zipper, and an integrated draft collar combine to further enhance overall warmth and comfort. The YKK zipper prevents snags and has a two-way design that allows for easy venting. A compression stuff sack and storage sack are both included.
