800+FP Ultra-Dry™ Down 7D Nylon Ultralight Sleeping Bag

Specs are listed towards the bottom of the page! 

These are some of the most premium bags in the industry - no question. 

Top of the line materials including 7D nylon, all warmth ratings internationally certified, the highest quality ethically sourced 800+FP Ultra-Dry™ treated down, and well engineered baffle construction, and boy are they LIGHT - more than enough to compete with the best bags in the industry.

In fact, they are made using the down from one of the biggest RDS Certified manufacturers in the industry, so although this company hasn't paid for the official RDS Certification themselves, you can sleep well at night knowing the down is coming from a humane place. 

If you need a seriously light yet reliable sleeping bag, you are in the right place.

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! These bags pack down to the size of a water bottle! 

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 down is also Ultra-Dry™ treated - which means it is coated with a water-repellant that keeps it from absorbing water! That means that if it gets wet, the down will hold it's loft and keep you warm, when non-treated down would likely collapse and reduce the effectiveness of the sleeping bag - this is very important! 

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. 

What is 7D nylon and why is it good? 7D nylon is currently the thinnest "tough enough for hard outdoor use" nylon on the ultralight backpacking market right now. It's so thin that you can literally see the down fibers inside the sleeping bag when looking at it. 

There are some huge benefits to this! Number one: breathability - 7D nylon is WAY more breathable than the thicker 15-30D nylons used in most "ultralight" sleeping bags - no more soaking the inside of your sleeping bag with sweat!

Number two is of course weight - this stuff is LIGHT. If you go to any hardcore "MYOG" (Make your own gear) backpacker and ask what they're sewing their own sleeping bag with, it will likely be 7d nylon! 

NOTE: Bag Weights include compression sack - subtract roughly 50g for actual weight.

Temperature Rating: As a rule of thumb, the “Limit” rating should be applied for men, and the “Comfort” rating should be applied for women. If you tend to sleep warm, look to the limit rating, and if you tend to sleep cold use the comfort rating. 

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!
