Thanks for reaching out!
We are happy to make some suggestions of lighter packs for you, however, your best bet would be to go in to your local REI store to get a pack fit or to sign up for a virtual outfitting appointment with one of our expert pack fitters. That way you can talk about your specific needs and get the right pack matched for you. In the meantime, we encourage you to check out this Expert Advice article, How to Size and Fit a Backpack, for lots of good information about choosing the correct size backpack for you.
Additionally, choosing the right backpack for you is not only about getting the correct fit, it is also about the equipment you are putting into it. Backpacks are generally measured by liters of volume, in addition to torso length, and that helps determine how many days worth of gear the backpack can carry. For many reasons, there is a lot of variability in these numbers, so a backpack's size will be highly dependent on your style of backpacking (do you bring a backpacking chair for lounging around camp? or are you drilling holes in your toothbrush to shave weight?) and personal preference. We would caution against going with an ultralight backpack if you haven't also made the investment in ultralight gear as well. An ultralight backpack is great, however, it can be very uncomfortable if you overload it with too much gear.
Here are a few backpacks to consider, in the 60-75 liter range, which is generally accepted as a 3+ day backpack:
- MYSTERY RANCH Glacier Pack ~70 liters of volume.
- Osprey Aether 65 Pack ~65 liters of volume.
- Gregory Baltoro 65 Pack ~65 liters of volume.
Hopefully this helps, thanks!
