Last week I found a backpack on sale, and although I already have other bags, I decided to pull the trigger as it was a great deal for $2,000 MXN (around $110 USD).
The comparison will include:
•Patagonia Mini MLC in Current Blue (New bag)
•Osprey 26+6 in Black
•Aer Travel Pack 3 Small in X-Pac
I usually use the osprey as an under-the-seat backpack and for short weekend trips. Mainly use it in the unexpanded mode.
The Aer is for the business trips where a laptop is needed. Always put it in the overhead compartment as it takes my legroom away.
I think that the Patagonia is a bag that sits between the Osprey and the Aer, can be lightweight but also has a dedicated laptop sleeve.
I decided to do a packing test to see how they fare against each other and to see which one is more comfortable. I hope this is also helpful for anybody out there deciding between these backpacks.
For the test, i packed the following items:
- Thule Medium packing cube
- 2 casual trousers
- 1 hoodie
- 2 shorts
- 1 swimsuit
- Decathlon large towel
- Thule Small packing cube
- Underwear and socks
- Peak Design Small packing cube
- 7 t-shirts
- 2 sports t-shirts
- Pgytech Medium packing cube
- Banket just to fill the volume, as I didn't have more clothes to fill the cube
- Decathlon Dry bag
- Teva Hurricane
- Osprey Ultralight zip organizer
- Toiletries
- Laptop
- Thinkpad X1 Yoga
The Osprey has more capacity when in expanded mode. However, due to the form factor, the weight is far away from your back so it kind of pulls you back. It still has a little room available after packing it. Without the exansion, it would probably pack everything but the Tevas but without room to spare.
The Aer is the smallest of them all, as expected but it's very close to the Patagonia. My Tevas didn't fit in the main compartment, so I put them in the admin bag, sacrificing tech storage. It's also the heaviest, so be prepared for it.
The Patagonia seems very promising, it's very spacious and very comfortable when fully packed. Footprint is very similar to the Aer but I'm not sold on the admin panel protruding against the laptop, but I don't carry too much tech into my trips. Anyone had a problem with the charger damaging the laptop?
I have a trip in December, and I'll be testing the Patagonia in a real scenario, traveling with a laptop on a week-long journey. The last issue is that if I like it, I'll probably have to sell one of the other backpacks (probably the Aer). We'll have to see.
