Ok, I've looked at a lot of pannier-backpack transformer bags, and this one is the best.
- Transforms from one to the other very easily, I live and bike down to -30C and can flip pannier to backpack and forth without freezing my hands
- LOVE that the top carrying handle is in the middle of the bag instead of on the edge - my other panniers are Arkels and I find them great for touring but when you have to carry them in your hands they bash your legs up. Not so with this great 2WG bag! Carries like a briefcase if you want it to, no leg bashing around!
- The company was super transparent and helpful about negotiating how to get the bag to me with the postal strike happening, I found them very responsive and friendly, and real problem-solvers from the logistical end
- The fabric is waterproof and quite tough, and doesn't become brittle in the cold - you can tell they are truly designed for all weather
- I really appreciate the bright coloured rain cover, I got the black bag for the office but still like to be visible while out on the road
- I really like the bright coloured inside, makes it easy to find stuff in there; also the pockets are the right size and shape to carry phone/wallet/glasses etc. Impressive thoughtful design!
- I got the smaller size bag, which fits my smaller frame body really well (I'm 5'6"). I would imagine the larger bag might be too low on my back, and am super happy I went with the smaller option :)

My only suggestion for improvement is putting more reflective surfaces on the bag; but the visibility issue is solved with the bright rain cover, so not complaining about it at all!
All in all, I can only say good things about this bag. I've been looking for the right one for a while, and am so so happy I found this one!

I bought my pannier/ backpack about 2 years ago, and absolutely love it. I commute 3 miles to work several times each week, year round. The bag holds exactly the right amount of stuff (phone/ wallet + laptop, notebook, cords, with some room for clothes), keeps everything dry, and the conversion process is easy and simple. I never write reviews for products, but love this bag so much I'm motivated to let the world know! Very well designed, and constructed.

I bought this pannier a year ago as a birthday gift for myself, and have used it every day since. Every. Day.
I don't drive, I strictly bike everywhere, and this pannier is the first to be able to keep up for so long. I have put it through everything, from rain, snow, sleet, to mud, and it took it all and still works like new! It gets used as an everyday work bag, groceries, day pack, and everything in between. I used it on several tours, and I am certainly not known to take great care of my stuff, so I got used to having to replace panniers each fall, but this one I can barely notice any wear. It truly lives up to the hype, and you can stop looking for a better pannier, because as far as I can tell, this is as good as it gets.

Fantastic pannier/backpack! Easily converts from one to another. As it happens today was the first day I used it and got caught in a downpour. The pack itself was water resistant and I made sure to stop and put on the accompanying rain guard - worked great. It’s compact (I got the 22l) but holds a lot of stuff. Lots of pockets for organization, and the bottle holders on the sides work well too. Upon first use, very pleased with my purchase.

This pannier is ideal for commuting to work, utilitarian (e. g., grocery shopping) errands, and even a weekend bike tour.

It is well made; the backpack straps hide away nicely; the upper rack attachments don't cut into my upper back; it is water resistant & a rain cover is included. The description of the 22L Pannier Backpack Convertible 2.0 Lite is accurate.

If I still worked (I'm retired but do lots of bicycle advocacy stuff) I'd use this pannier every day.
