Nice bag, but more of a 30F than a 20F.
Good quality TNF bag. Sent it back after reading (more than a few) reviews that it was more of a 30F bag than a 20F. I did not test this my self but went for the 0F snow leopard TNF bag because it would be warmer for my needs. Great bag for summer- mild fall camping. Maybe not the best if you plan on being warm on a 25F night. If you read recommended use it is rated a 3 season bag, so if that is what you need I would say its a good choice.
