Sure this bag has 75 L of volume, but not all volume distributes equally. This bag is very narrow and tube like, so weight expands up and not across, placing a lot of weight and restriction on the T and C spine and limits head movements. Personally, I also found that this weight distribution made me feel very unstable with my footing. If you're using a hydration pack, take note it'll be a tight squeeze whether you place a filled hydration pack before or after packing the main compartment. If you opt for water bottles, the side pockets have little to no stretch and is best for a flat water vessel, not a Hyrdoflask or Nalgene. This bag is okay if you're entry level or don't have any particular needs. Otherwise, for the more experienced or for those who prefer more customizable options, this bag is not recommended.
I purchased this sack because my 17-year-old 50 litter Kelty Redwing wore out that's right 17 years! Used every spring and fall. My pack weight usually is between 30 - 35 lbs. I was planning on buying another 50 litter when REI put Caldera 75 litter pack on sale. Before purchasing I considered that before putting anything in the pack I would add 2 additional lbs. over my Kelty. But the price drew me in. I am training for 2 nights in the woods. And so far, this pack has been AWESOME! I did not realize how outdated and worn my Kelty was. The balancing act of getting everything inside and outside this pack has gone away. I Can get absolutely everything inside pack including tent poles with it balanced perfectly on my back. I weigh my pack every carry and been able to stay my 35 lb. limit. carrying the same items as I carried with my Kelty. Could be its packed better everything on the inside. My highest milage training day so far is 8.7 miles 1600 ft elevation no back are shoulder pain
