I need to be up front and state the I have not yet tried this pack on the trail. But have had it on my back with about 35lbs and it felt great….like it could really handle the load. I bought this as a downsize for my Gregory Baltoro 75L pack, which is a fantastic pack. Both packs are heavy by today’s UL standards but both utilized comfortable wrap-around hip-belts, well cushioned shoulder straps, and other innovative features to make heavy loads feral much lighter for long days on the trail. I suspect that I will come to love this pack.
