OESB Synthetic [Size: Regular -10]

Only 1 Left!

The OESB (Outdoor Education Sleeping Bag) Synthetic is a great bag for general use: it’s robust, easy to look after and warm even when damp.

It’s available in three temperature ratings (ISO 23537.1 limit of comfort -2, -5 and -10°C) and small, regular and large sizes. The generous mummy shape makes it both comfortable and thermally efficient, while the squared foot-box is complemented by a full-length YKK #5 locking zip with anti-snag cover. (This zip allows it to be easily opened from the ankle for effective venting.) Made from robust Vapour Vent V2 fabric, it’s filled with multiple layers of thermally-bonded Thermolink to maximise performance while minimising size and weight.

  • Generous mummy shape maximises thermal efficiency without restricting movement or comfort
