    • Decent to 20°
Style: 20°f Big & Tall Size: Contains PFAS
Tested out a couple weeks ago where temp was just at 20°F. I'm a cold sleeper and I felt a slight chill at feet and legs, but warm everywhere else. I'm 6'3", wide shoulders, and size is plenty. With a little more preparedness in clothes layering I think I would have fared much better. One annoyance was the Velcro flap for top of zipper. Had to really fuss during the night reaching around to free it from it's anchor point and pull over zipper to keep it from unzipping, which is it's purpose and performed fine after all the fussing. Personally don't think the extra strip of Velcro to keep the flap out of the way is even necessary. I ended up putting a blank strip of Velcro over with non lock side out so I don't have to release the flap each time I want to place it over the zipper. Otherwise very pleased with the bag, especially the roominess and ability to turn without the whole bag moving with you. ... show more

    • Very large, rather comfortable, terrible stuff sack
Style: 40°f Big & Tall Size: Contains PFAS
Great for car camping for larger individuals. I'm rather athletic and over 6' so it is nice to have a larger sleeping bag to spread out in. The mummy hood is rather awkward in most cases, but the material is flimsy enough that it isn't obnoxious unless the zipper is zipped all the way up. The real win in this design is the feet zipper. Being able to open the base of the bag up and put my feet out during warmer nights is luxury after a long day of exertion. The bag is very bulky and I wouldn't recommend it for overnight hikes. For a base camp at the trailhead or for car/RV camping, I loved it. I bought several bags to try at once and ended up using this one over 20 nights of traveling and car camping. The stuff sack is trash. Trying to get the bag back in was always a 5 minute effort. I expected the stuff sack to tear every single time - but somehow didn't... Great warm weather bag (or cooler weather if you're a hot sleeper) with cheap feeling materials that is very comfortable to sleep in. ... show more

    • Solid bag! Very comfortable, does the job
Style: 20°f Size: Contains PFAS
I really liked this bag. Its a great size, fit me perfectly (6'0, 170lbs) and I was so so so comfortable in it. My only qualm with it was its weight and size since I wanted a backpacking bag. Otherwise this one did the trick, would recommend.

Amazing sleeping bag. Size; I brought XL & being 5'8"/185lbs I have plenty of room to twist / turn. Warmth; no heat in RV, 22 degrees for a few days & never felt chill inside the bag. Climb in the bag at 9:30pm & comfortable until 7am wakeup. I must have read reviews for 50 sleeping bag, extremely happy with this purchase. ... show more

    • Ok but
Thought it'd be great but the inner lining feels to plastic & uncomfortable, & it's too heavy to carry around. No for me tho.
