I was searching for a new sleeping bag liner to take with me while travelling, as it is often the most compact and convenient thing to take to hostels that don't provide bedding. They're also useful as a bit of extra warmth in your sleeping bag or helping to keep it clean / for guests use. The cheapest I could find on ebay was around £8 then I found this at Argos. 190cm long (approx 6ft3), 2 yr guarantee and machine washable. Comes in a handy carry case approx 15cm by 5cm diameter when rolled. Free reserve and collect as always with Argos, or delivery is £3.95
Add 2 to your basket and its 2 for £5.98!
