Amazing travel bag

I bought this for a trip to Thailand. So far I've used it on every domestic trip I've taken and it's perfect. It fits under the seat on Delta, united and southwest. It packs down. There's a ton of zipper pockets to separate things out. There's so many different ways to wear it. Best pack I've ever used.

Best Travel Pack EVER!

I cannot say enough good things about this pack. My two most favorite features are that it opens like a suitcase (everything you pack is easy to truly access), and it fits easily in carry-on bins or UNDER THE SEAT in front of you (even in aisle seats, no joke!). I only travel with a carry-on and I AM PICKY about my bag. This bag has all the right compartments in all the right places, and not too many. Hands down the best bag I've ever travelled with (from weekends to two-week trips). This is the third one I've bought; my husband finally gets one :)

My new favorite travel bag

I'm 6'6", so finding a bag that was going to be comfortable on my frame was my key goal. The 42 vs. 35 is a small difference in size, but it just fits me better and the added benefit of the load lifters and shoulder strap just gives me so many more options to get it perfect. And looking at the bright colors just makes me smile every time. And I have to add, Cotopaxi's support team was fantastic. I had a few questions about the differences between the 35 and 42, as well as between the Allpa and the Del Dia versions. Answers were quick and detailed. Thanks!

Have not yet used it but unpacked and examined it, and it seems to be I hoped.

Excellent quality

The Allpa 42 is an awesome bag for one bag travel. The compartments help keep things organized and I love the covering on the front of the back..

Great features in a travel backpack but pretty big size

I love all of the features in the 42l Allpa travel backpack. The front organizer pocket perfectly fits the hip bag full of things. The load lifters, removeable hip belt, rain cover, and most importantly water bottle pocket are all welcome features. The organization is also really well done and provides plenty of space for creativity. I wish the Allpa 35 came with more of these features because I worry this 42l pack won't work for international carry-on. Another concern I had is that there are a lot of external zipper access points but none of the zippers seem readily compatible with TSA locks. The anti-theft loops at least are welcome additions. Lastly I loved the colorway of the indigo and all-black bag. I ultimately chose the indigo for concerns that black would absorb too much sunlight and run hot.

Perfect and Chic for travelers

I take it on the road with me even if I don’t need that much space to pack. It gets lost of attention and the best part is that it gives back to local communities. What’s not to love!
