In reply to hutster781:
Not used their sleeping bags before, but the rest of the kit I have used, gloves, hat and a jumper, are of excellent quality. As mentioned above, the sizing is Japanese so everything is smaller than UK sizing. I'm generally Small/Medium in UK sizes and had to get a Large or Extra Large jumper (can't remember which off the top of my head!). I believe they have a shop in Switzerland, so you might be able to contact the shop to find out the exact sizing of the sleeping bags?
