At just £170 the Robens Caucasus 600 is instantly appealing to anyone on a tight budget. It has a good temperature rating of -2 to -8 deg C, making it ideal for 3-season use. The insulation is down, like all the other bags in our test, but with just a 600 fill power it isn’t quite of the same quality as the higher-priced bags, so you need more of it to stay warm. The outer is made of nylon like most alternatives, while the inner is polyester, which doesn’t feel quite so nice but helps to keep the price down. The insulation is trapped inside a box wall construction and appears to be well distributed through the bag and its baffles. There is a side zip that extends to the calf area, and this has a good anti-snag strip and baffle inside. The shoulder baffle gets a drawcord, and there is a hood drawcord too, so there’s plenty to like about the Robens Caucasus 600. The drawback is there’s no extra water resistance at the head and foot areas, as some higher-priced bags offer; and more importantly it’s quite heavy at 1225g (1289g with stuffsack). It packs down quite small, though, thanks to a very good compression sack. Lightweight backpackers will benefit from finding some extra cash for the higher-priced bags, but if this is your budget then the Robens Caucasus 600 is great for the money.

The Robens Caucasus 600 is a very good 3-season bag with a low price tag; but it’s relatively heavy, making it less than ideal for backpacking unless you really can’t stretch your bank balance.
