I ordered the Flex 30 6'6" wide with 2 oz overfill. I am 6'2" 210lb. This quilt is simply amazing! The quality, comfort is awesome, fits perfectly with plenty of room to move around. Have used it down to high 30's with only shorts shirt and wool socks and slept like a baby! The pad attachment is easy to use and most of the time I use the elastic straps and keep it closed up on me to eliminate drafts. If in the 50s I leave the foot box snapped but open. I use it almost every night as my primary quilt on my bed. Open it up, snuggle in. Only thing I would like done or may do myself is add a snap above the zipper so that when your realy active turning over at night that you don't unzip the zipper which has happened to me a couple of times when I sprawl out. Other than that I am most definitely pleased with my service, purchase and experience with my first Katabatic Flex quilt! I already know I will be buying another one colder rated from them before winter! Probably the Alsek 22 or 15, not sure , maybe both! Don't hesitate, if you come this far, get it, you won't regret it!
I REALLY want to love this quilt. It's well made and the pad attachment system is fantastic. My first and only night out with it came with temperatures in the low 40s and I was colder than expected.
Disclaimer- I'm not a cold sleeper, nor am I new to quilts, I have sufficient ground insulation and base layers on. The weight is close to spec and it should have been warm enough, but was not for some reason. Perhaps the down had shifted, or there was some other user error but I wish I had gotten the Flex 22 instead.
Quality product with lots of versatility. Beats the competitors in terms of materials and design. I love this Katabatic
My only preference would be for a slightly sturdier zipper, if only for piece of mind.
This is my second Katabatic Flex. I've owned a 15 for years and love it. Wanted a 30 for the warmer times of the year. The craftmanship is flawless, the strap system works absolutely great and the ability to open it all the way when you want is awesome. I am a Katabatic Gear customer for life. Also, i emailed them and explained that i was in a bit of a rush and I had my quilt super fast. Keep up the great work. THANKS!!
I recently took my new Flex 30 quilt with me to the Olympic National Park for a late winter two-night backpacking trip. The first night, it ended up being much colder than I'd anticipated, well below freezing. When I woke up, my tent was literally covered in a crackling sheet of ice. While perhaps it would have been better to have a Flex 20, I was able to get by with thermal underwear, a nice liner, and an extra blanket. The thermal protection was probably much like any other 30F bag, and I loved the soft fabric, super comfy, but those things seem fairly standard in high-end quilts. The connection system is what really shined here. Before my hike, I taped the connector cords to the back of my sleeping pad and when it came time to dive in, I attached the little tabs on the underside of the quilt. This system is really the reason I bought this quilt and it worked great. I found, however, that if you don't clip it in all the way so that it locks tight, then the tab will come off the cord as you sleep, especially if you're a side sleeper like me and constantly turn from one side to the other. Having those tabs come off the cords really shows how valuable they were--the cold air seeped in almost immediately, leaving cold spots on my back. The next night, I made sure to pull them all the way tight on the cord and they stayed there just fine all night. I am a big guy with very broad shoulders and the quilt felt way more spacious and comfortable than any mummy sack. Really great.
Length: This refers to the maximum height of the user. For example, if you are 6’ tall, you should comfortably fit in our 6’ length, and the collar will loosely come up to your chin. If you are a stomach sleeper, you’ll want to add a few inches to your height since your toes will be pointed away from you, essentially making you “taller.”
Width: If your shoulder circumference measurement (around the widest part of your chest + arms) is 51” or greater, you’ll need to select a wide size. You can opt for a wide even if you don’t meet that measurement. Just keep in mind that if there is too much dead air space inside the quilt, you might sleep a little colder.
Fill Power (FP): Down with a higher FP number provides more loft, so we need less of it to achieve a certain temperature rating. Therefore, the finished weight of a quilt filled with a 900 FP option will be slightly lighter than one filled with the 850 FP down, but they would be equally as warm.
Duck vs Goose: Duck down is more readily available than goose, so it is less expensive. There are no performance differences, and one will not make your quilt warmer than the other. Note that our duck down is only available as an 850 FP, so the quilt would be slightly heavier (see above).
HyperDry: This treatment helps the down maintain its loft better in damp conditions, and helps it dry out faster if it does get wet. The HyperDry treatment is most useful for folks who will encounter a lot of humidity or rain, or will sleep numerous successive nights with lows in the teens (°F).
