You get what you pay for
- Familiarity: I've used it several times
I bought this bag because I was on a budget and it seemed to be the best bet for the money I could spend.
Took it on a weeklong trip to Olympic National Park. Obviously it packs heavier than a down bag, but that doesn't bother me too much.
The stuff bag it comes with works pretty decent for a synthetic bag, though I don't believe it actually packs down to 8.5 x 8.5, like the specs say. Mine seemed to be a couple inches bigger.
Also not sure about the 30 degree rating, it may be closer to 40.
I'm 5'2'' and got the short bag and there was plenty of room to spare.
Overall, I was satisfied with the bag I got for the money I paid.
