Great Ultralight BackpackReview by JT
This is an outstanding pack for Ultralight Backpacking !! I have taken it on multi-day hikes in the Green mountain of VT and the White Mountains of NH and its waterproof fabric has held up to some interesting New England weather. The fabric is really durable. I used the Murmur 36 Hyperlight Backpack as a basis for getting into the sub 15 pound range for equipment and it has made all the difference. (Posted on 1/19/16)
Love this PackReview by marisa
This was given to me as a gift from my boyfriend about a year ago. I've used it several times on backpacking trips and I'm very happy with it. It's unbelievable how light it is. One of my favorite features is the ultralight removable pad that acts as cushioning against my back. After arriving at camp I take it out and use it as a seat, and as additional cushioning under my sleeping pad at night. I also love that it has the accesories on the front to hook my trekking poles.

Sweet little packReview by Marco
What a nice pack! I had it out a little more than two weeks since I had it. It really did the job. I was amazed at the fabric, so thin and light, yet strong, too. A really, really nice pack.
