Criterion Quantum Range Specifications
Table Footnote – Quantum Range
- 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.
Criterion Quantum Range Features
Other Criterion Quantum Features
- Top Baffle Construction – Quantum 350 and 450 down sleeping bags have trapezoid baffle upper construction. The Quantum 200 uses a boxwall baffle upper construction due to the amount of down in the bag.
- 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. In our Quantum range of bags 60% of the down is in the top of the bag with 40% in the base.
- 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.
- Cowl hood – A spacious hood with one-hand-operated drawcord and plenty of room to turn you head.
- Integrated anti-snag zip baffle with neck warmer – A down filled baffle runs the length of the zip in Quantum sleeping bags at the top of a 90° turn makes the baffle into a neck warmer. As the baffle is open down can be moved up and down to suit your needs.
- 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 Quantum 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.
- 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 – All of our sleeping bags are supplied with a size-related stuff sack for use outdoors and a breathable, 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.
