I really like this pack and and wonder if anyone has done any modifications to gain a few ounces,or any ideas from lightening other packs. I know about changing the the compression straps to cord and cordlocks and the top closure to a lighter cord. I previously used a Go-lite Breeze to which I added a hip belt, it was considerably lighter than the Circuit but not a better bag overall. I carry about 13lb without consumables and have used the Circuit on the AT and with a bear barrel on the JMT.
