Criterion Expedition Down Sleeping Bags
Down Sleeping Bags designed for the most extreme cold weather conditions on Earth
Our Expedition range consists of two down sleeping bags, both designed for extreme cold weather conditions typically found in polar expeditions and high-altitude mountaineering, such as the Himalayas.
Made with a combination of Pertex fabrics our Expedition sleeping bags keep have been designed to be practical as well as warm. The outer shell is made of Pertex Quantum Pro which is a windproof, waterproof and extremely durable fabric (Please note the seams are not taped so the bag is not waterproof). The inner sleeping bag is made with a combination of Pertex Quantum 52g/m² and Pertex Quantum Pro. Pertex Quantum Pro is used in the footbox and the inner hood, areas of possible higher abrasion. Between the footbox and hood Pertex Quantum 52g/m² is used which is a softer more breathable fabric.

Criterion Expedition Range Table Footnotes
- Fill Volume: is a measure of the total insulating power of a sleeping bag. It is a useful metric to be able to compare the different fill powers and fill volumes of down in a sleeping bag. As a rule of thumb the higher the fill volume the more insulation there is in the bag. However, fill volume is a guide and does not account for differential fills or baffle design, which also may affect temperature ratings.
- The main part of the inner is made from crimson Pertex Quantum 52g/m2 ripstop fabric (formerly called Pertex Microlight), but critical areas (ones that may get wet in extreme conditions or areas of abrasion) are made from the same Quantum Pro fabric as the outer. These include the hood inner, and the footbox.
Criterion Expedition Range Features
Other Criterion Expedition Features
- Differential Fill and Cut – More down is placed in the top of the bag rather than the base. As your body heat rises extra down in the top of the bag ensures better insulation than if all the down was split equally. The down on the base of the bag traps some body heat and combined with a good sleeping mattress acts as a barrier, preventing heat being lost to the cooler ground. Our Expedition down sleeping bags use 60/40 ratio.
- Trapezium Footbox – Trapezium Boxfoot – A trapezium is a four side regular shape but unlike a rectangle it only has one pair of parallel sides rather than two. Our boxfoots are wider at the base and taper to be slightly narrower at the top of the bag. This helps to suit all feet types and sleeping styles.
- Expedition hood – Designed to provide the best protection, our Expedition hood has full baffle with a one-hand-operated drawcord, to keep heat inside the sleeping bag .
- Insulated neck baffle – Two independent down-filled baffles to trap body heat, one for below the neck, the other for above. These can be closed and cinched with Velcro fasteners and an elasticated, one-hand-operated drawcord.
- Full length YKK zip – A two-way YKK zip runs the full length of the bag. This allows venting from both the head and foot of the bag. All of our bags have a Velcro neck retainer so the bag can be closed even with the zip open.
- Choice of zip sides – Our Traveller range is available with zips on both the left and right hand sides. Left and right handed zip models can be zipped together if required. All of our sleeping bags (with the exception of the Expedition range) can be zipped together with bags of different ranges.
- Double Down-filled zip baffle – Two full length down-filled zip baffles prevent cold spots and heat loss. The baffles also has a lightweight zip stiffener to reduce zip snagging.
- Inside pocket – A functional inside pocket allows the safe storage of valuables such as a wallet or phone.
- Hanging loops – Two hanging loops are fitted to the boxfoot of the bag which allows storage on a coat hanger or airing on a washing line.
- Stuff Sack and Mesh Storage Sack Included – Comes with a heay duty stuff sack with grab handle for ease of use, and a mesh storage bag for use at home if needed. We also offer a range of optional roll top dry bags. for use as stuff sacks.
