Combined with the 4S Outer, this can be used all year round in sheltered places.

    I have owned the 4S Inner for the last 15+ years and have used it extensively in conjunction with an MOD issue sleeping bag. Trust me, it makes all the difference to that 4am experience when you start to feel the cold under you and it becomes difficult to drift back off – this has never been an issue with the 4S Inner. I also use it quite often on its own indoors where it is perfect for just rolling out when needed. Virtually indestructible, it has worn the years well! I just need to find someone that sells the Thermaliner now so I can use it outdoors on its own in warmer weather!
