I bought this product after thorough research of the options. Examining offerings from Big Agnes, Exped, Nemo and others, I landed on the Basecamp for it's universal compatibility with sleeping pads, an excellent price point, and design that included a well designed, mummy bag style hoods that can be cinched to a pinhole. or opened up for warmer eveningsThis 2 person sleeping bag surpassed all expectations as a comfortable 3-season 2 person option. It is cost-effective, light and warm for a synthetic bag. It works well for both car camping and backpacking though, being a 2 person bag it is obviously on the on the bulky side. This was tested with the Exped Synmat Duo though it includes pad straps making it nearly universally compatible.

After 40 years of buying at least 20 different sleeping bags I've finally found the one. This has several great features that I really haven't found elsewhere. It packs up surprisingly small for a "basecamp" bag, smaller than my previous backpacking bags excepting a 50° i use during warm weather. Secondly this has plenty of shoulder girth, which is rare. I can get both arms in comfortably, I have a 48" chest. and have had a hard time finding a bag that fits me well. Lastly it's good for anything from 50-20°. I bought the 10° bag and it might be a bit cold at that temperature, but at 20° it does great. With two side zippers and a foot zipper you can make it work in warm temps too, or use it as a comforter. Lastly it's a got a functional hood you'll actually use. A 5 ... MoreAfter 40 years of buying at least 20 different sleeping bags I've finally found the one. This has several great features that I really haven't found elsewhere.

I love everything about this bag except it is not as warm as the rating would suggest. Long story, short, I'm at 5'11 190lb male, and I will be treating this bag as comfortable down to 40 degrees, not the 20 degrees that was advertised.I took it camping when the temperature was supposed to get below freezing, maybe 28 degrees. I had long underwear on, wool socks, and a beanie, and I was in a tent with the rain fly on and two of my kids (so all that generated and retained some heat...maybe a few degrees). Anyways, there was no way I was staying warm enough in this bag. I'm confident I would have survived, but there would have been no sleeping. Luckily, I brought my Rumpl blanket just in case, so I threw that over me and was fine after that. I also have a 20 degree ... MoreI love everything about this bag except it is not as warm as the rating would suggest.

Luckily, I brought my Rumpl blanket just in case, so I threw that over me and was fine after that. I also have a 20 degree synthetic bag from REI, and you can tell it is just a more substantial bag. I gave that to my friend for that trip (he slept in a tent with his kids) and he was fine. Not sure if the difference is just the size/width or the level of the insulation. This is a bigger, wider bag than my REI bag, so it's clearly going to take more body heat to keep it warm.But I love everything else about the bag, and I am going to keep it. I like the quality of the material, the packed size, and the roominess. I sleep on my side with my arms bent up and hands near or under my pillow. Most mummy bags constrain this. Also, I like to have a little room for my legs to move around. So, I love this bag. It's just not as warm as advertised.

My husband is 6 foot tall and 250 lbs and was able to fit comfortably in this Basecamp Down sleeping bag from Sea to Summit with plenty of room to spare. This sleeping bag comes in its own storage bag and a thin bag was included. Plus it’s orange which he loves. Now we need to book a camping trip.I received this product compliments of Influenster.
I'm a 5'4", 245-250 lb (3x-4x) woman. Most sleeping bag/mummy bag options out there don't work for my body type. I also tend to move around a lot as I sleep, so I was so happy to find Sea to Summit has these "roomy" options. I got the regular size, 10 degree bag and it was a great fit. Please make sure to advertise these bags to the plus size community because we're looking for these options!I tend to sleep on the warm side, with the exception of my feet, so I was excited to test out how this bag would hold up when I found out that the first evening of a planned camping trip would get down to 30-35 degrees.For reference, my sleeping pad was a Klymit Insulated Static V Luxe with a yoga mat underneath it and a camping blanket nearby in case I needed more warmth ... MoreI'm a 5'4", 245-250 lb (3x-4x) woman.

Pillow was a Sea to Summit regular size Foam Core pillow. Hopped in the bag that evening with my base layer on, some wool socks, liner gloves, and a beanie. Got an amazing night's sleep! Didn't need the blanket. My feet were a little chilly in the morning, but that was because I forgot I could attach myself to the pad and managed to wiggle down it while sleeping to where my feet weren't on the pad anymore. The bag is so soft and comfortable too. I cannot wait for my next camping trip!
Sea to Summit makes high-quality products and this sleeping bag is no exception. We already have a sleeping bag from this brand, so I didn’t have any doubts when ordering this one. It is super lightweight but very warm. All the detailing is precise and crafted perfectly. The sleeping bag is warm and it is very comfortable. The insulation is distributed evenly throughout the bag. it comes in this storage bag, but there’s also an included attachment to clip it to your backpack. It doesn’t take a lot of space, but it can be even packed more tightly.
I'm 5'9" and a somewhat cold sleeper. To that end, I know that I need a bag with a strong temperature rating. I was looking for a bag for spring/summer/early fall kayak camping when temps are not less than 40-50 degrees, and this will suit me fine. However, I slept on an insulated pad in temps no lower than 50 degrees with a pair of synthetic thermals on and while I never got cold, you could feel the chill through the top of the bag. Therefore, there is no way I would trust this in lower temperatures for my own comfort. (This isn't an unusual problem in bag designs from most manufacturers, but I wish the industry would do better.) Having said that, the biggest pro is the expansive shape for a side sleeper.

(This isn't an unusual problem in bag designs from most manufacturers, but I wish the industry would do better.) Having said that, the biggest pro is the expansive shape for a side sleeper. Cons: the weird, stiff materials used around the zippers and the measly straps. This is advertised as luxurious bag and the pad straps were a real part in my decision, except that they barely fit around a 25x33" pad and the straps never remain snapped. Why design a larger bag, but not allow that people who might want or need this kind of design would also then appreciate or use a larger sleeping pad? Go figure. I got mine for a very good price, because while I like it, I don't feel it's a $200 sleeping bag.
Awesome bag. Super roomy. I like the strap attachments for my sleeping pad. It keeps it flat. I can roll around without getting tangled. I love the ability to open it on either side and the bottom to vent if I get warm. I have slept in it around 30 degrees amd in the 50's and was super comfortable. I haven't opened it to quilt yet, but maybe this will put my summer bag to rest. It packs down nice, considering how wide it is. The down is lofty and has no smell. No regrets.
I’m super impressed with the quality of this sleeping bag. It is beyond comfortable with duck down feathers that are safe to get wet. It has so many features for a sleeping bag such as, many different zippers , pockets, a phone holder. It folds up so small and compact. I love that they do field tests with their products before they sell them. Definitely high end quality.
This bag is absolutely amazing! My feet are usually cold so I wasn’t sure about having such a large toe box. I was wrong… I was toasty warm in mid to low 30s, sleeping in thin pants and a t-shirt. I did a bit of cowboy camping in Paria Canyon (Utah/Arizona) with this bag paired with my Recharge XL Sleeping Pad and was super comfortable. I was amazed that there was no cold air seeping in from the zippers. Not only have they designed this bag to have the zippers overlap, they have zippers on both sides. As well, the toe box has a separate zipper in case you have a warmer night and need to air out the toes or kick out a leg. I was super impressed. It’s hard for me to sleep in tight spaces so the flexibility to sleep however I wanted and still have room to switch sides, ... MoreThis bag is absolutely amazing!

The bag has straps so attaching it around my sleeping pad made it to where it did not move at all through the night even though I was. Overall hugely impressed!
