User Review: Kelty Men's Cosmic Down 20° (Kelty Trekker)
Price Paid: $50 at Target
Have used this bag for over a year now. For what I paid ($50) it can't be beat. Light, lofts up well, and keeps me warms right down to its 20 degree rating.
The fabric, zippers, and seams look like they're brand new. I've spent about 25 nights in it from backpacking on the AT to camping on the snow in the backyard.
I would highly recommend this bag to anyone looking for a half decent down bag.
Update: February 26, 2012
I actually spent a few nights in the bag while it was in the 20s to see how low it would go. One night it hit 19 degrees F, and I was fine with a base layer and hat on. The draft collar is great, as I don't like to have the hood cinched tightly (though it does cinch down to golf ball size).
To be honest, my bag is called the "Kelty Trekker" and was purchased at Target. The specs and bags are identical. After speaking with Kelty, I found they make gear for Target made under the Kelty name — some with the same specs, but named differently.
