It may have been the cheapest on test, but how did it perform under review?
The Hunka isn’t the most breathable bag tested or the lightest weight. It is by far the least expensive however, and the breathability is adequate and the weight reasonable – many bivi bags weigh considerably more. I’ve only had slight traces of condensation in the Hunka, although I’ve not used it in really wet conditions.
The design is simple, just a tapered envelope with a shaped, drawcord-closed hood and a shaped foot. The hood is big enough to cover the entrance to keep out rain but the best way to do this is to have the opening under you. There are drawcords either side of the hood so you can easily grab one however you are lying in the bag. If you do end up with the top of the bag under you, as I often do even when it’s not raining, there is no hard cordlock in the middle of your chest.
There’s ample room inside for a winter weight sleeping bag, although no space for much other gear. There is an XL size for big people and huge sleeping bags. The tapered shape means the Hunka fits well round a sleeping bag. It’s best used on a mat rather than with a mat inside as the latter distorts the shape and reduces the inner volume too much. A neat touch is a mesh pouch on the foot of the Hunka into which it can be stuffed so no stuff sack is needed.
Unless weight is critical or you want higher breathability or extra features such as a zipped closure, insect netting or short poles, the Hunka is an excellent bivi bag. It does everything needed at an amazingly low price. The only minor drawback is that it’s only available from Alpkit so you can’t see it in a shop.
