Meindl Jura GTX

The Biopod DownWool Ice 200 from Gruezi Bag is a mummy-style sleeping bag built to keep you warm and dry during cold-weather camping. Its mix of down and wool insulation offers reliable warmth without feeling clammy, making it well suited for outdoor adventures where temperatures dip near freezing.

The heart of this sleeping bag is its 70% duck down with a 650 fill power, complemented by 30% wool. This combination delivers high loft and excellent heat retention from the down, while the wool fibres wick away moisture and help regulate temperature. The shell is crafted from lightweight 20-denier nylon, offering a durable barrier against wind and light moisture. With a tapered cut measuring 230 cm long and 85 to 55 cm wide, it provides a snug fit for taller campers up to around 200 cm, minimising excess space and reducing drafts.

Fill power, indicated here at 650, measures the down’s ability to loft and trap air – higher values mean more insulation for less bulk. The wool adds resilience by absorbing any moisture that down can’t handle and maintaining warmth in damp conditions. The 20D nylon refers to the fineness of the fabric’s fibres: lighter strands make the shell both thin and strong, helping to keep overall weight down without sacrificing durability.
