Highlander Sleepline 350 Sleeping Bag

The Highlander Sleepline 350 Mummy Sleeping Bag is a warm and comfortable 2–3 season sleeping bag designed for camping, Duke of Edinburgh expeditions, festivals, Scout camps and family outdoor adventures. Combining a thermally efficient mummy shape with quality insulation and a soft-touch lining, it's an excellent choice for cooler spring and autumn nights when extra warmth is essential.

Designed with a mummy-shaped profile, the Sleepline 350 helps retain body heat more efficiently than a traditional rectangular sleeping bag. The adjustable thermal hood and insulated neck baffle work together to trap warmth around your head and shoulders, reducing heat loss and helping to keep you comfortable throughout the night, even when temperatures begin to drop.

Inside, the sleeping bag features a soft cotton-feel polyester pongee lining for added comfort, while the 350g/m² mono hollow fibre insulation provides excellent warmth without excessive weight. The durable 190T polyester shell is built for regular camping use, and the full-length zip with insulated baffle makes getting in and out easy whilst helping to minimise cold spots along the zip.

Weighing approximately 1.4kg, the Sleepline 350 packs neatly into the supplied stuff sack, making it easy to transport and store between adventures. With a comfort rating of 5°C, lower limit of 3°C, generous dimensions of 230cm x 80cm x 50cm, and a packed size of 44cm x 23cm x 23cm, it offers an excellent balance of warmth, comfort and packability for a wide range of outdoor activities. The temperature ratings have also been independently tested to EN ISO 23537-1:2016, giving you confidence in its performance.
