Comfort is not 'one size fits all', which is why the Boost 650 empowers you to customize its shape to find your perfect balance of space and warmth. As a spacious semi-rectangular sleeping bag the Boost provides all the room you need to side sleep, shift about, spread out and relax. The semi-rectangular shape gives you considerably more internal space than a mummy bag-you'll feel unrestricted and free to sleep in whatever position you want all night long. But more space demands more body heat to warm it up and cold isn't comfortable. That's where WarmZip comes in.
