Wind River Sleeping Bag: -10F Down

Warm and light weight

[This review was collected as part of a promotion.] This a great cold weather sleeping bag with dual zippers. It's very light weigh and can be compressed in a medium bag. Ideal for fall and spring hiking. I'm 6'2" so the long is a perfect size.

Compression stuff sack recommended

[This review was collected as part of a promotion.] Good sleeping bag. Needs a compression stuff sack for anything but car camping, but that’s a really cheap addition for a bag of this price

Cozy!

Familiarity:

I've used it once or twice and have initial impressions

Size Bought:

Long

It held up great on low temperatures on a hike in the mountains. I was very pleased with it ! It really kept the body insulated from the outside environment.

Used at Chimborazo high camp 5300 m.

Amazing Sleeping Bag

[This review was collected as part of a promotion.] Amazing sleeping bag, I just got it a couple of weeks ago, have been using it in the field for 2 weeks now. I always get cold at night, and wanted to invest into a forever sleeping bag that could protect me from the cold. It is extremely warm, roomy and comfy. We had mostly nice weather, but 3 very cold nights (around -3°C), my tent mates felt cold during the night in their sleeping bags and I slept warm and comfy in my shorts and a t shirt. The only thing that I would change is to make the zippers longer (or at least one of them). So I could have more ventilation in the feet area. Everything else is wonderful, I'm super excited to have gotten this sleeping bag.

my first impressions

I have only tested this in high 20sF on a winter camping and this is my impressions: 1- it does not compress that much, 2- it is easy to adjust the bag around the face without pulling ur hand out of the bag. 3- there are two zippers on each side one of which only opens from the inside of the bag. u can use them as a ventilation option or u can pull ur hands out of the bag to do any chores in ur tent while the bag is closed over ur head and shoulders. 4- I had issues with the main zippers. 9 out of every 10 times that I tried to zip up or down, they would snug no matter how careful I was with holding the fabric away from the zipper. 5- the foot box is very comfortable and the zipper on it helps with ventilation.

Warm bag with nice zipper options

[This review was collected as part of a promotion.] The way that it folds down like a blanket is nice! More importantly, thee is no need to choose “left zip” or “right zip.”. The expandable footbox is a nice feature! Keeping it zipped and compressed in cold weather adds warmth. I also own a zero-degree bag but the travel size and ravel weight of this -10 degree bag isn’t much more. I like the color too!

You had me at dual side zips!

The wind river sleeping bag is really versatile. I love the dual side zips and roomy feeling of the bag, and ease of entering and exiting. As an added benefit the dual side zips allow for extra ventilation if the inner temperature gets too high; and when I zip the dual zips up to my chest I can comfortably sit in my sleeping bag in a down jacket and keep my hands and arms free to read, eat, etc.. When the temps get low it’s easy to close down the hoody and neck baffles to keep all my heat inside. Getting a good nights sleep when on an adventure in cold environments is absolutely critical and this bag will deliver! Enjoy.

Not the best.

[This review was collected as part of a promotion.] It's definitely a worm sleeping bag. However, it is cumbersome for backpacking and I've found that it tends to leak feathers. The fact that it only has 650 fill power means that you have to have an under quilt, or respective sleeping matt.
