I love the quality of the materials, the feel, the loft.
Foot box works well.
Wish size small had wide option. (I am 5’ 5”” and 115 lb….side sleeper….but would just like the possibility to wrap around me more, even knowing point of quilt is to save material and weight). Wish the pad attaches were not so unwieldy (and worry with sharpness they could puncture my air pad). Wish I could figure out how to cut out drafts altogether or at least more successfully as I am still chilly at 40 degrees. Maybe some user error here but I am trying my best.
A great addition to my kit! I already had the 15 but needed something for warmer weather.
So pleased by how it takes so little space, and the unique foot box closure saved the day when I had an oops with how I rigged my underquilt, leaving my feet unprotected otherwise. Kept me snug on a windy rainy 38⁰ night in my doorless hammock setup. My stepson was a complaining chilly mess in his less expensive competitor 30⁰who was in a tent.
The flex of it being able to fully open makes even a 30⁰ very versatile for warmer eves, and saves your bones having that warmth available when the weather man is, um, "surprisingly" wrong about the next morning.
Flex 30 kept this cold-sleeping 70yr old very comfortable last night in the UK Lake District, -2C outside the tent, minimum base layer with hat and socks. Strap/clip system takes a bit of getting used to but soon appreciated the options it gave me (particularly for that those nighttime excursions). Available in Europe from Peter at outdoorline.sk
This quilt is awesome!
Besides being made with an actual durable fabric, Pertex Quantum ripstop (0.85oz/yd), rather than the extremely fragile 7D fabrics (Zpacks 0.51 oz/yd) other cottage makers use that will leak down (because they are on the edge of being calendered/downproof), the design/baffle engineering of this quilt is much better than its competitors (including Nunatak). This means it wraps around your body in a 3D fashion much better than the flat made quilts (like Enlightened Equipment) retaining its loft better and making it easier to move within it. This generates a small increase in weight for the shell material but reduces the down fill weight even though Katabatic bags give you an extra 0.25" of loft for a given temperature rating compared to the competitors (2.25" for 30 degrees compared to 2.0").
All this enables Katabatic to mark their quilts with a "comfort" temperature rating rather than the safety or "transition" temperature rating everyone else uses. A Katabatic 30 is the same warmth as everyone else's 20 rating. Additionally, Katabatic does all the details better, the collars, the zippers, snaps, and reinforcements, and the pad attachment system are more functional and durable than the competitors.
I recommend the Flex 30 as your main quilt (with the NeoAir UberLight pad). How often will you be sleeping on snow in the winter? If you don't plan to do that then the Flex 30 will keep you comfortable from 60-25 degrees if you have a jacket/puffy and beanie with you. In mild temps it is really nice to just use it as a blanket. If you are sure the night time lows will be >50 degrees go buy a sub 1 pound sewn through down blanket off of Amazon for
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).
