Great Bag, Especially for the Price
This bag is extremely comfortable and has kept me warm everytime I've used it. Since it's down it compresses extremely small which saves weight. The temperature rating is perfect for your late spring to early fall trips depending on where you live and your destination. Can't recommend it enough, especially for a starter bag.

Kelty cosmic down review
Item is good quality and is a great low cost down bag. Changes I would make are bump the down fill up to 600 fill power (really only would help marketing the bag) and include a compression sack and storage sack. Otherwise pretty good bag for the price.

Backpacking Bag - Hunting
While I did not use this for backpacking (stayed near truck) on my week long elk hunt in Idaho, I would recommend it to be used as a backpacking sleeping bag. It packs down very small. First couple nights were lows in the mid 30’s and it kept me comfortably warm. The rest of the trip lows were around 45 and I had to shed layers down to my skivvies to keep from sweating. Overall happy with it as you can’t prepare for unseasonably warm temps.

Nice bag
Used on a sub 50 degree night around Labor Day. Bag was very warm and I think it would be fine for me probably well under 40 degrees. The only complaint I have and this isn’t on the bag it’s me, is that I have little room to move my feet in the foot box. Again, that isn’t a reflection on the bag. Because i realize that cold weather bags limit space to work better. But I likes to move my feet! Hahahaha.

Nice bag and construction - sizing is not accurate.
I am 5'11 and 200 lbs and barely fit in this bag with hood up. The shoulder area is extremely tight and needs to be expanded. Overall the quality of construction, warmth and materials are great. Just wish the sizing was true to the stated measurements.
