UOG TOP PICK - Sierra Designs Cloud 800 20 Sleeping Bag - If you don’t want the restriction imposed by a zipped bag and don’t fancy a quilt because you move around too much at night then the Cloud 800 bags deliver unrestricted rest when you want it and warmth when you need it.
The Cloud 800 Sleeping Bag is a truly innovative design that really stands out from the rest. The zipless opening with oversized comforter really works especially for people who move around during the night, people looking for extra room in their bags and anyone who likes to cool off quickly.
Sierra Designs says
Welcome to the most comfortable night’s sleep you’ll have in the backcountry. Hailed as Outside magazine’s “Best Sleeping Bag For Backpacking” and an evolution of our award winning Backcountry Bed, the Cloud features a zipperless design with an integrated comforter. Constructed with 15d nylon ripstop fabrics and 800 fill power DriDown™, delivering an ultra comfortable lightweight mummy. To top it off, the Cloud touts our patented self sealing foot vent and a pad sleeve, allowing you to vent heat and move around without worry.
Our Verdict
Sierra Design's have developed a unique sleeping bag in the Cloud 800. There are a number of practical features that you only truly appreciate once you're using the bag. The zipless, quilt style opening that wraps around you seems like a gimmick until you get to enjoy how easily you can get in and out of it. The opening has an oversized comforter which acts like a quilt so you can really wrap yourself up in it if the temperatures drop. Alternatively you can quickly and easily open it up to dump heat if you're too hot.
Sierra Designs use something called 'Temperature Mapping' in this sleeping bag. This is when they use less insulation on the back of the sleeping bag and add sleeves to attach your sleeping mat in place. This may seam strange but by keeping your mat securely in place it will keep you just as comfortable and warm, replacing the unnecessary bottom insulation, thus saving you weight. The best aspect of the bag for me personally is the self sealing foot vent. I get hot feet so restrictive mummy bags are often uncomfortable due to feet that are overheating. On the Cloud you can easily slide your feet out of the vent on the bottom to cool off or just let air in. Due to the placement of the vent and the overlapping materials, as soon as your feet are inside there no chance of cold air getting in or your feet accidentally getting out. An ingenious design feature.
This version has 419g of 800 Fill Power DriDown that has a -3°C Comfort Limit so its good for two to three season use, particularly if you're a warm sleeper. The fabrics used are 15D so they are lightweight but also more than many of the lightest bags out there. The dimensions of the bag are generous so it would suit someone after a larger bag, someone who moves around a lot at night and warm sleepers. The overall weight is really impressive given all the features too.
