Temperature RatingEN Limit +6° C/43° F | EN Comfort +11° C/52° F. As a rule of thumb, the “Limit” rating should be applied for men, and the “Comfort” rating should be applied for women.

This is an absolutely fantastic, comfortable summer, spring, and fall bag made of extremely high quality down. Fully certified temp ratings means you can confidently bring this on your trip, and the zipper and nylon are brand name and won't let you down on trail. The 20d nylon is just thick enough to not let down seep out like some of the thinner options out there, while still being very lightweight. 

Pair this with a nice insulated sleeping pad and you'll be good to go for most of the year!

If you're wondering what 800 Fill Power down actually is, it is basically a "fluff" rating for down. The higher the number, the fluffier it is. What does that mean for you? Well the fluffier down allows the manufacturer to put less of it in the bag to fill the space between the baffles - and that space is what traps warm air to keep you warm. So basically, a high Fill Power rating like this allows you to have a much lighter sleeping bag without sacrificing any warmth at all - in fact it has more room for air, so it can often feel even warmer! The range you will see in sleeping bags goes from about 450FP to 900FP, so "800" is one of the highest down ratings on the market!

Another huge benefit to high fill power ratings like these are that they also compress much smaller, so they are easier to fit in your pack!

You may be wondering then why all down products don't just use the fluffiest down - who would use 500FP down if 800 is better? The answer is simple: cost. Nice down like the stuff in these bags costs a ton more than the 500-700FP downs that you'll see in lower-end products. 

This has a 90/10 fluff to feather ratio, which seems to be the ideal industry standard for keeping the down fluffy and still light. 

REMINDER: These bags will only keep you as warm as the sleeping pad you put them on - to insulate from the cold properly, make sure to pick up a properly rated insulated sleeping pad to go with it! When you lay on a sleeping bag the baffles that are below you squish flat, which makes it so they can no longer hold heat in that area - the insulated pad takes care of that for you so that you can stay nice and warm!
