This bag is designed to go down to 0 C, which would make it suitable for late spring through to early autumn in the UK. I've used this bag with a bivy bag in temperatures down to -15 in wet Welsh and English weather on the top of hills, and I've stayed warm enough if I keep some clothes on. I've also used it in the middle of summer and been toasty. The bag packs down tiny (buy a compression sack - Ajungilak make some good ones) and lofts out quickly. Very happy with this purchase - the only problem is that when it gets wet, you get cold - but with the Pertex outer, it's reasonable water resistant from condensation drips and dew etc.
