Mountain Hardwear's Ratio Sleeping bags use 650 Fill Power down to achieve excellent warmth to weight ratios with hydrophobic down as standard they represent good value for money.

Mountain Hardwear says:

The right bag for backpackers and campers ready to step up to down. The Ratio 32 offers reliable warmth in summer and shoulder seasons, thanks to the unique Thermo Trap Baffle. 650-fill Q.Shield DOWN retains maximum loft in damp conditions. The soft, luxurious lining is cozy and inviting.

Mountain Hardwear's Ratio sleeping bags achieve excellent EN ratings for their weight, they are filled with 650 Fill Power down that's also hydrophobic (MH call this Q Shield down), so it's performance when damp will be much better than untreated down.

Comparing the stats we think the Ratio series of bags are good value for money, they don't have quite the performance of the more expensive bags but the price difference is significant.

The cut of the bag is such that the front comes high up to your face so the widest part is a little way down from the opening, the opening itself is quite small - the Ratio bags don't have a shoulder baffle but with this design its probably not worth it. All the other features are there, roomy boxed foot. zip baffle, cinch cord around the opening.

Get this if you want to trade up to a down bag but can't justify the price tag.

**EN13537:2012 - Look for the 2012 label for the most accurate rating; In 2012 the EN system of testing sleeping bags was re-vamped - the new testing procedures are more rigorous, producing more consistent results than previous tests. 2012 results tend to rate sleeping bags as poorer performing by a few degrees when compared to previous test results, even though the sleeping bag may be identical, or even better.

This means that comparison between an EN13537:2012 rated bag and an EN13537:2002 rated bag are particularly difficult - our advice is to use the new EN13537:2012 rating to compare with other bags who have also been rated in this way.
