We bought these to trial as a dofe expedition option. We find that Yp turn out with in appropriate grade of bag. So we needed to offer an option ifbwatm and light and affordable. This bag is that. On a cold weekend in September we put it through a dofe weekend. It fitted well in a rucksack, kept us warm overnight (temp dropped to +3 ).
The double zip didn't cause any cold spotting it added to ease of access. All in all we were suitably impressed. The sale price made it excellent value for money. Normal price makes it a more considered purchase.
