Used their UltraLite on a three-day Mt Baker trip camping on snow in temperatures down to 20°F and had no issues with being cold.

Loves their MegaLite but considers it, like their other WM bags, comfort rated: comfortable to around freezing and starting to feel the cold below that.

Uses the SummerLite for spring and fall high-desert trips and an AlpinLite for summer alpine trips. Was borderline too cold in the SummerLite on a windy canyon rim near Escalante in early March in a tarp tent, so would not take it for winter desert trips.

“TBH, I have been borderline too cold in the SummerLite on an early March trip to Escalante/Glen Canyon on a windy canyon rim. I was also in a tarp tent, so didn't have ideal wind protection.”

Recommends Katabatic over Enlightened Equipment for a wide 20°F quilt and says their own Flex 22 has been awesome.

Owns an AstraLite and finds it great and really warm for its one-pound weight. The strap system is fine but nothing special, and the sizing is confusing: at 5'10" they just fit the 5'8" size. Later adds it was good around 28°F on an XLite with a fleece, as a colder-than-average sleeper.

“I've got an Astralite. It's great. Really warm for the weight (one pound flat!). Strap system is good, nothing special I guess. Their sizing is a little confusing”

Has pushed their NanoLite to about 30°F and found its 38°F rating spot on: that is exactly where they started getting cold in base layers.

Used the Palisade on the AT in 2016, where it was more than needed, and still picks it over their WM AstraLite for trips without freezing temperatures. Finds it snugs better with a better balance of feel, durability and breathability in the fabrics, and doesn't bother with the straps.

“For most trips where I don’t expect freezing temps I pick the palisade. It snugs better, and the fabrics seem a little better. Right balance of feel/durability/breathability. I don’t use the straps for either.”

Has spent a few shivery nights in their Alsek near its lower limit. Says the Katabatic closes well but still leaves a cold spot at the footbox, and learned that the warmest possible sleeping pad makes the biggest difference.

“Also something down to block the footbox hole is helpful. The Katabatic close well but you still get a cold spot down there when pushing the lower boundaries.”

Bought the 20°F UltraLite for a September JMT section and woke up cold every morning although it never dropped below 30°F. Dislikes the very shallow hood that won't stay around the head, but says it is otherwise well made and came in about 1.5 oz under the advertised weight.

“I recently bought a WM 20 Ultralite for a section trip on the JMT in September and each morning I woke up cold. Didn't get below 30 a single night”

Has taken their MegaLite down to 15°F and vouches for Western Mountaineering rating its bags conservatively.

Has owned the SummerLite for 15+ years and calls it a real 32°F bag at 19 oz that became their go-to three-season bag. Has since moved mostly to quilts and wonders whether a modern version has better materials.

“I've been very impressed with the WM summerlite over the years. It is a real 32F bag @19oz that ended up being a go to 3 season bag for me.”

A cold sleeper who found the Katabatic Flex 22 manageable at 30°F on a weekend trip, and is now looking for something to layer with it for 10°F nights. In the thread they add that the Katabatic pad attachment system is really nice.

“I have a Katabatic Flex 22. I am a cold sleeper and it was manageable at 30F this weekend, but I will be venturing out into some 10F in the coming months.”

Bought the AstraLite in 2022 for the colder CDT and owns a Katabatic Palisade too; finds the four-degree difference in their ratings about right. Still picks the Palisade for trips without freezing temperatures because it snugs better and its fabrics feel a little better.

“But I bought the Astralite in 2022 for the CDT bc it’s a colder trail. Plus, it saved an ounce or something? I’d say the four degrees difference in their ratings is accurate enough.”

Was comfortable all night in the SummerLite in the central Cascades at around 30–32°F, wearing Alpha sleep layers and down booties on an R6.9 pad. With more layers they would take it to mid-20s forecasts, and say it packs smaller than a football.

“Just came back from the central cascades, temps must've bottomed out at 30-32F where I camped and with alpha sleeping layers I was comfy with the summerlite all night long.”

Is 6 ft and loves their regular-size AstraLite at about 500 g, especially the design of its draft collar.

Loves their AstraLite and fits it fine at 5'11". Brings the straps on most trips because they are needed when cowboy camping in a breeze, and as a slightly cold sleeper on a 7R pad has used it comfortably into the upper 30s °F and uncomfortably into the upper 20s.

“I bring the straps on most trips, but I also like to cowboy camp, and I think they're necessary if it's breezy. I've used it comfortably into the upper 30s and uncomfortably into the upper 20s”

A warm sleeper and big fan of the AstraLite who has used it comfortably down to the low 20s °F, crediting its efficient cut for how warm it is for the weight.
