QEZER 650FP Four-Season Mummy Down Sleeping Bag

Lightweight Down Warmth for Every Season

The QEZER 650FP Four-Season Mummy Down Sleeping Bag is designed for camping, hiking, backpacking, mountaineering, and cold-weather outdoor travel. Filled with 650FP premium white duck down, it provides lightweight warmth, soft loft, and excellent compressibility without unnecessary bulk.

With multiple temperature rating options, this mummy sleeping bag is suitable for conditions ranging from mild three-season nights to extremely cold winter campsites.

How to Choose the Right Sleeping Bag Temperature Rating

Choose your sleeping bag based on the lowest nighttime temperature expected during your trip. Select a colder-rated option when camping in changing weather, at higher elevations, or if you usually sleep cold.

  • 46°F: Best for spring camping, cool summer nights, mild fall trips, indoor use, cabins, and general three-season outdoor travel.
  • 10°F: Suitable for late-fall camping, early-winter trips, cold mountain nights, and temperatures well below freezing.
  • 0°F: Designed for winter camping, snowy conditions, and cold-weather trips where stronger insulation is required.
  • −8°F: A warmer winter option for very cold campsites, high-elevation trips, mountaineering, and extended exposure to freezing conditions.
  • −22°F: The warmest option for extreme winter camping and severely cold outdoor conditions when paired with a properly insulated sleep system.

Tip: Temperature ratings are a selection guide rather than a guarantee of personal comfort. Wind, humidity, altitude, shelter, clothing, sleeping pad insulation, and individual cold tolerance can all affect how warm you feel.

El mejor saco de dormir para temperaturas bajo cero.

Color: -8 Degree

Mi novia es superfriolenta y le gusta dormir hirviendo. Lo usamos a 13º y no sintió ni un pelo de frío, yo lo probé y me sentía muy incómodo por el calor, si durmiera con él a 0º tendría que abrirlo o solo cubrirme parcialmente.

Es compacto, muy compacto para el calor que provee. Quizá 20 litros. Además, es superamplio, de todos los que he probado ha sido el único donde pude girarme y dormir en cualquier posición que me ocurriera, además de cubrirme por completo la cara y cabeza.

Voy a comprar uno para mí, por qué creo que lo puedo ocupar cómodamente en cualquier montaña mexicana sin gran problema incluso en invierno e incluso en nevadas. Creo que incluso voy a considerar comprar el de 1300gr en vez de este de 1500gr por que me gusta dormir frio.

Actualización:

Necesitas. Una bolsa de compresión adicional!!!!!!

Adquirí el Therm A Rest Questar 0F por que tiene un volumen de 10L aunque cuesta casi el doble que este. Después descubrí que si este lo metía en una bolsa de compresión propia podía reducirlo hasta 12 o 13 litros, adjunto foto.

Te recomiendo que compres este y una bolsa de compresión adicional para hacerlo realmente chiquito.

I bought two of these down bags. Both are well built. The zippers are perfect and the bags zip together. The 650 down fluffs nicely. Shipping was about 3 days (I'm in Denver) looking forward to my first winter night!!

Nice sleeping bag

Color: -8 Degree

Nice and warm. Although at last I didn’t get to test it at -15C (too cold and switch to sleep inside instead) but nice sleeping bag. Come really compressed and hard to put back to the original bag. Not too heavy as well.

Great Value In A Down Sleeping Bag

Color: 10 Degree

I generally prefer synthetic fill sleeping bags because they're easier to wash and maintain, and they retain more of their thermal insulation when damp or wet, but my synthetic winter bag was too bulky when ultralight motorcycle camping so I purchased the QEZER 0 degree sleeping bag for a smaller packed volume and I've been very pleased with it. I've slept in it for approximately 60 nights and it's holding up very well. I'm 6'2" and this sleeping bag should fit people up to 6'5" or maybe an inch or two more. I always buy the long version but this is the longest sleeping bag I've ever owned so it's long enough for tall people curled into a fetal position without stretched cold spots at the feet. The width is perfect for me. I'm fairly heavy and the sleeping bag is my ideal width - not too tight but not so loose that I'm carrying extra bulk and weight and trying to use my body heat to warm a lot of excess air. I like a fairly fitted mummy bag. If you're on the large side and claustrophobic, this mummy bag may be tighter than you'd like.

The liner is a very soft nylon that has a very nice feel, and unlike my other winter sleeping bag, the liner material on the QEZER is almost instantly warm. With my synthetic bag, I crawl inside and shiver for five minutes until the bag is warm. The QEZER down bag is warm almost the instant I hop inside. The material is a bit loud and crinkly even though it feels soft and supple, which seems odd.

Zipper quality is very important and I'd knock off a star because the zipper is not as nice as a YKK zipper, but at this price, that would be unfair. The zipper is adequate. It hasn't failed in a lot of use. It catches occasionally, but even the best zipper and draft shield design has the occasional zipper jam that's easily fixed by unzipping a few inches, realigning and zipping. I should try a drop of silicone oil to see if that improves the smoothness of the zipper, but the zipper works well enough that I haven't bothered.

I'm a cold sleeper so I wouldn't be comfortable in the QEZER 0 degree bag at 0 degrees Fahrenheit, but I bought it for use down to 32 F and it's good for that. I won't be motorcycle camping when it's colder than 32 F at night. If I needed a colder rating, I'd buy a thicker sleeping bag. Down compresses very well for a minimal bulk in my pack. I'm loving the small packed size of this winter down sleeping bag, particularly when I stuff it into the spaces around other packed objects, but be sure to use a good insulated pad under you because a sleeping bag can't keep your back warm when your weight compresses the insulation.

-22F version comfortable to 0F

Color: -22 Degree-Coffee

The -22F version kept me comfortable at +5F. I think it would be good to 0F. I put a puffer jacket between me and the zipper at colder temperatures. Great bag.

Excellent sleeping bag. Used in -17C temperatures and it was really warm. It holds body temperature very well. Very good size for 6ft tall.

Took this in my RTT across country in the winter without a heater. This thing is unbelievable, clothes or no clothes, temps were in the low teens, didn't matter!

Great bag

Color: -22 Degree-Coffee

Great sleeping bag for the price, I’m not sure you can find a better one. Although the first one I got came with a hole in it, it was still very warm and they sent me a new one very easily, no complaints.

Great bag!

Color: -22 Degree

Love this bag. I get cold easily and this bag kept me super warm. A little big and doesn’t pack down as small as I hoped but it’s worth the warmth.

Llegó antes de lo estimado.

Color: 0 Degree

Pedí el de 0F, lo utilicé en La Joya, en Iztaccihuatl y cero frío, esa noche nos llovió y hubo ráfagas de viento y cero quejas, solo dormí con una térmica y una playera de running. El único cons que veo es que sí necesitas una bolsa de compresión pues sí ocupa bastante volumen para intentar guardarlo sin problema en tu mochila.

Lo recomiendo para bajas temperaturas? SI.

El material se siente de buena calidad. Yo mido 1.62 y me quedó un leve grande, pero honestamente no lo veo como un problema pues a la hora de dormir tuve completa movilidad.
