Good summer bag

  • Familiarity: I've used it several times

I've used this several times in warm weather. The coldest I've slept in it was around 45 F (7 C), and if I hadn't been wearing a fleece shirt and a hat it would have been chilly. It does stuff fairly small (it should, there's really not much insulation) -- I took it on an Africa trip in my carry-on bag along with a Big Agnes Qcore SL pad and a blow-up pillow. These gave me the flexibility to bed down just about any place.

I do wish it came with a storage bag, but an old pillow case works fine for this purpose.

If you can get the closeout price of $30 someone was mentioning, this would be quite the bargain.

Light bag

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

They are still selling these at north face outlets. Picked up one this weekend in cinci for 29.99. Going to try out for warm weather. Super small pack size and only 1 lbs 10 ounces.

Nice bag for warm climate

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

I live in Costa Rica, very warm climate and thought this bag would work fine here. I wasn't wrong. This bag is thin and perfect for what I needed. As besp168390 says the red color is more like burgundy and the black is more like gray. These came with a compression sack in black/dark blue color attached to the bag so you don't lose it. Very nice.


    I purchased 2 bags. Be aware that they are more burgundy than red. They come with a storage sack that acts like a compression sack. Quality build as usual. It's north face what would you expect. I got the regular and I am 6'1" plenty of room. These will make great summer bags when it cools off in the evening. I really got them for our vehicles. They will be great for winter in case of emergencies. They compress to about the size of a regular size coffee can, perfect for storing in the car. The bag is pretty thin so summer time is really the only season u may get away with late spring if u layer.
