The warmest of our synthetic fill Solar range, the Solar 4 Sleeping Bag is tailor-made for year-round camping adventures.

Built with a tough 20D ripstop outer and a soft 20D polyester lining to keep it relatively light and packable, the Solar 4 Sleeping Bag features a blanket base with shingled upper construction to help eradicate cold spots. The three-quarter-length knitted zip comes with a laminated anti-snag stiffener and insulated baffle; and the use of an angled foot box minimises empty space, improving insulation without restricting movement. Additional features include an internal stash pocket to keep your valuables close, plus a 3D draft collar and hood drawcord to keep you snug after a hard day on the hill.

With its breathable Stratus™ polyester sheet insulation, its differential cut and its trapezoidal boxwall construction, the Solar 4 Sleeping Bag is a highly practical four-season sleep system.
