Sturdy, practical bag

So far I have only taken this bag to the farmer's market, so I can't speak to how it stands up to heavy, repeated use. But it seems like this bag is sturdy and practical. It is large, with a high capacity. The clasps also seem more reliable and less fiddly than older models of Po Campo gear.

Love it!

It’s nice and spacious, holds a lot. Feels comfortable on my back and gets on and off the bike rack easily. I love the shoe/cooler component too - great design for that to be insulated. I also had an issue where the snap on the rain cover broke off when I first got the bag, and they sent me a replacement right away. Happy to support this company and love all the bags I have from them!

Functional as heck

This bag is amazing. I can't stop showing off the functions to everyone. I love the separate pocket underneath for lunch or shoes. The built in rain cover will surely save me one of these days. The backpack straps are easy to convert and comfy. So thrilled!

Awesome packnier

I don’t love the bottom storage pocket- I appreciate its potential utility, but most of the time, I just need a bag and don’t need a cooler or separate compartment.
