Last week we went shopping for Steve’s backpack for our SE Asia trip. Originally, our plan was to have him carry all our belongings, and for me to carry his camera bag. However, I think a better way is for him to still carry his bigger backpack, and I will carry a lighter backpack with essentials to carry when we’re out sightseeing or hiking.
With that in mind, we went to REI and tried out some backpacks for me. First, we decided on the proper size. This article has some basic information on how to choose a backpack. Although our trip is considered extended trip (5 days & more), we really can’t carry more than 70L of gears (that would be way too heavy!!). According to the REI staff, that pack is really for people who are carrying snow gears, rock climbing gears, etc. Since we have none of those, we thought multiday is the best for our trip and something good to have for future use.
Next, we figured out my torso size. My size is between an extra-small and a small. I tried on a few small packs, and they fit pretty well, so there was no need for me to try extra-small.
After that, it’s basically just trying out different packs, loading it with weights, walk around and see how it feels. We loaded it with about 25 lbs of weight, and it was heavy! So I think the ideal capacity for me is between 40L to 55L, because any higher capacity would just be wasted. It wasn’t that easy finding packs for women in the capacity that I want at the Berkeley REI store, but I did manage to try a few:

REI Venturi 40
This is the first pack that I tried on with 20 lbs of weight. According to Steve, this pack has a pretty good rating (function/price), although it wasn’t too comfortable for me. There was a lot of pressure on my hip bones (probably due to not enough padding). I also felt pressure on my lower back, which I supposed is due to the weight, not necessary the design of the pack. The shoulders were not too comfortable either, no matter how I adjusted the pack.
So I moved on.

Gregory Jade 50
I can’t remember the exact model for the second pack, but it was a Gregory, and I remember seeing this bag on the rack. This time Steve loaded 25 lbs of weight. Not knowing that the weight increased by 5 lbs, the first reaction I had after putting this pack on was that it was lighter than the REI pack! My hip bones didn’t hurt anymore, but I could still feel weight on my shoulders no matter how I adjusted the straps. I also still had the lower back soreness.
Overall, this is better than the last one, but I tried a couple more.

Deuter Futura Pro 34
Steve loved the Deuter! Deuter doesn’t have sizes because it is adjustable to your exact fit, however, I don’t think this one is adjustable, but anyway……We couldn’t find a Deuter multiday pack, so we tried the day+ pack. It feels pretty good! No pressure on my hips, the shoulders still had a bit of pressure, and lower back still sore, but overall, it was slightly more comfortable than the Gregory.
Next, Steve let me try the bigger Deuter bag just to see how it feels.

Deuter ACT Lite 60+10
I guess this is what I tried on last. Immediately after putting this pack on, the hips felt good and I didn’t feel the soreness in the lower back! Steve thinks maybe the Futura 34 is a bit of a stretch for 25 lbs. Everything feels great except the shoulders. For some reason it wasn’t covering my shoulder bones and it was creating soreness on my shoulder blades more than the other packs. Fortunately, this pack is truly adjustable where you can adjust the shoulder straps up and down. With a few adjustments, my shoulders were covered and not as sore as before.
The only problem is this bag is too big and I will never be able to carry it when fully loaded. But I guess we’re convinced that Deuter is a pretty good pack and next time we can narrow down to trying the other Deuter’s.
After trying out the 4 packs and walking all over the store with 25 lbs on my back, I was ready to call it a day!
