OmniCore Designs Multi Down Mummy Sleeping Bag (-10F Blue / 10F / Red / 30F Yellow) with Compression Stuff Sack and Storage Mesh Sack

This is my 2nd attempt on finding a “big” mummy bag that I can backpack with that will keep me warm on cold PNW nights that packs small(ish). I went with the “tall” because it was Prime, adding 6 more inches which I don’t need. The bag is BIG! I am a side sleeper who tosses and turns a lot. Having room is important for my comfort, making me a happy camper. For reference I am 5’4, 220 40 D size 14 and the bag has plenty of room and can fit into my pack with ease.Rated five stars for all the bigger lady adventures out there looking for a great bag that won’t suffocate you.If I end up cold on my next trip I will update my review. With a -10 rating I am hopeful I’ll be toasty!Happy Trails!

I Bought This For Myself As A Christmas Present. It Was 24 Degrees Outside On Saturday. I Set Up My MSR Hubba 1 Tent, And Used My Therma-Rest Sleeping Pad. I Went Out Around 10pm To Try Out The Sleeping Bag. I Curled Up In It, Wearing Jeans, A T-Shirt, And Wool Socks. Within 10 Minutes I Was Toasty Warm. I Decided To Sleep In The Tent Overnight, I Was Very Warm And Comfortable. I Woke Up In The Morning And Did Not Want To Get Out Of The Bag, It Was Cold Outside! Excellent Product! I Was Not Disappointed In Any Way. Buy This Bag, It Really Works!

Went on the first cold weather campout (Virginia area) with this sleeping bag, lows at 28 degrees with no wind chill. I had multiple cold spots in this bag around the zipper, feet, and on the sides mainly my back or my left/right. This made it very hard to stay warm during the night. If I turned over or moved, it felt like I had opened the sleeping bag and let all the cold air in.After receiving the bag, I had unpacked it and shake it free and let it air fluff, and let unpack the fibers before its first use.

I've only had the opportunity to use this bag once since I've gotten it, but I have to say that I'm impressed. I used it on a single night camp out in Colorado. It was a clear, dry night, but the digital thermometer I had with me in my tent said the temperature went as low as 17 degrees during the night. It was cold! I had this sleeping bag, as well as a bag liner, thermals, and fleece pants, jacket and cap on all night. I can't say that I was overly warm all night, but I was comfortable enough and the bag was roomy and comfortable to sleep in. I wouldn't recommend sleeping at cold temperatures with the bag alone, but with proper layers, it's a nice bag for the price. I also really like how easy it is to stuff in the stuff sack. No trouble at all and still light weight! I have not sleep in more expensive bags that are similarly rated, but for a casual camper like me, this is a good bag!

I needed a better sleeping bag since my old year 2000 $30 Magellan one (pictured) wasn't warm enough or big enough. It had great build quality for the money, but had a zipper on both sides with no zipper flaps, which made it leak heat like crazy. I believe it was rated for 32 F, but was really cold at that temp. This Omnicore -10 F model does seem to be warmer due to its mummy design and single zipper w/flap. It is just barely big enough for my height, 6'5". However, the build quality is probably cheaper than the old Magellan. Yes, cheaper than my old $30 bag from 20 years ago. It will be interesting to see how this design holds up. The tag says "Designed in San Francisco" and "Made in Bangladesh".Also it is a bit tight. There's just enough room in the shoulders (I have broad shoulders) and legs, but not really enough elbow room. It would be easy to get claustrophobic in such a relatively tight bag. Also no zip-in inner sheet, unlike the Magellan.There's a cell phone pocket inside, and a pocket at the feet, which could be used for a flashlight or other item that needs to be located in the dark.Zipper appears to be very good quality, less prone to snagging than the Magellan. However, it did still snag, but it didn't get permanently stuck.I'll give it 4 stars for now and come back and give it 5 if it surpasses expectations.

When I got the product the ad for it is misleading for it presents itself as being able to go to -10 degrees, then one has to then decipher what is actually meant with the ad. The ad also says one who is 6'3" would have the ability to fit in the bag, guess what it's too short for me who is only 6'2". As I was getting ready to send it back you get a surprise, they are going to charge you for something that up front does not work, again there is nothing said about the penalty for returns, that should be clear and up front, not hidden until you need to return for one reason or another. And I'll never look at any other of their products again. Especially when you are punished for returns.

I bought this sleeping bag winter 2019-2020. I am 6'5 225lb and it fit me, but would probably not fit anyone even an inch taller. It kept me warm in just shorts and a t shirt on a 20 degree F night twice. The third time I tried to use it, when zipping it up the zipper ripped off and tore a huge hole in the sleeping bag (see photos). I contacted the company and will update this review based on how they respond.UPDATE: They responded the same day and shipped me out a new one for free which arrived in a week. Great customer service!

I picked this bag up for van camping on a camping cot. I have tested it twice, and it gets warm quickly. It is a roomy mummy style, meaning you have more room to maneuver inside than traditional mummy bags. There is an insert inside that makes a bit of noise when you move, which would be my only con observation. Buyers should pay attention to how these type of bags are stored, and it's not rolled up or stuffed...you need to leave it uncompressed so the loft is maintained, and only roll/stuff it when getting ready to use it on a trail. If you think you will occasionally need a reasonably priced bag that can handle cold weather, this will be a good investment.
