Price Paid: $100
Very good warm weather bag. It packs down small, and has good loft for a lightweight summer bag. The zipper only allows it to be used as a quilt for one, as the down doesn't extend to the bottom of the bag.
- Relatively low weight
- Mesh storage bag included
- A bit pricey without the discount for 650 down
- Zipper could be longer
Purchased this bag deeply discounted at $100; the regular retails for $199 and the long for $219. As of June 2017 it is still available with big discounts on many websites.
I sleep warm, so this bag allows me to sleep comfortably down to 40 degrees in wool 150 weight base layer shirt and long johns.
I have the Ratio 45 long left zipper, and I carry it in a Sea to Summit XS eVent dry compression sack.

The bag is a summer bag. It weighs in at less than two pounds (the long comes in at 1 lb 11 oz). It is available in left or right zipper. I chose left because the door on my Kelty Gunnison 1.3 is on that side.
Above is the Ratio in its mesh storage sack.
This is my late spring/early fall bag. I use The North Face Aleutian 55 in hot weather when I know I will be sweating in the morning; it is synthetic and therefore allows for machine washing. My cold weather bag is the Kelty Cosmic down 21.
The bag is well made with good loft.
I would recommend it for backpacking in warm weather when carrying a true three season bag provides too much insulation to sleep comfortably.
