I had the old Exo 58, which is great, even for larger loads than 35lbs. I finally wore it out on the JMT. Got a replacement Exos 58, but had to put on hip pockets since they removed them.
Looks like they put them back on the Exos 58 and Exos Pro 55. Might not be worth buying for the pockets, but that extra 1lb savings is tempting me to look at the Pro.
