Mummy sleeping bag High Peak TR 300 — polyester, 55–85 cm width, 230 cm length, 1.64 kg

High Peak TR 300 is an XL mummy-style sleeping bag designed for three-season use (spring, summer, autumn). The shell and lining are polyester: the outer shell features BIONIC-FINISH®ECO water- and soil-repellent treatment that is PFC-free, while the breathable, skin-friendly lining enhances comfort. Filled with High-grade Dura Loft® H1 siliconized hollow-fibre, the TR 300 offers good loft, high insulation capacity, durability and compressibility. The bag measures 230 cm in length with a variable width from 55 cm (shoulder area) to 85 cm (foot area), packs down to approximately 19.6 L and weighs 1.64 kg. Additional features include an adjustable contoured hood to reduce heat loss, a full-length two-way zipper with anti-snag guard and zip baffle, an internal pocket with Velcro closure and a supplied compression bag. The TR 300 accommodates users up to 200 cm tall and is machine washable at 30°C.

Advantages

The TR 300 combines a mummy silhouette with extra space for improved comfort while maintaining thermal efficiency. Siliconized Dura Loft® H1 hollow-fibre filling retains loft and insulating performance even after compression and repeated use. The BIONIC-FINISH®ECO treated shell provides durable, PFC-free water and soil repellency for better performance in damp outdoor conditions. Practical details such as a two-way zipper with anti-snag guard, a zip baffle to reduce cold spots, an internal pocket and an ergonomic zipper puller make the bag easier to use in the field. The supplied compression bag minimises packed volume for trekking and transport.

• Trekking and multi-day hikes where compact, compressible sleep systems are needed

How to use

Unpack the sleeping bag from the compression bag and allow it to loft before first use. Use the adjustable contoured hood to reduce heat loss around the head; tighten or loosen according to comfort and temperature. The two-way zipper allows ventilation from the foot end or full opening for use as a blanket; always ensure the anti-snag guard is aligned when operating the zipper. Store small items such as a headlamp or phone in the internal pocket with Velcro closure. After camping, follow care instructions by washing at 30°C and drying thoroughly before packing to preserve insulation and material properties.

Usage recommendations

For optimal insulation, keep the sleeping bag dry and use a groundsheet or insulated sleeping mat underneath. When compressing for transport, avoid prolonged compression during long-term storage to preserve loft; store the bag loosely when not in use. If conditions are damp, allow full drying before stowing and reapply a water-repellent treatment compatible with BIONIC-FINISH®ECO only if necessary and according to the manufacturer's guidelines.
