I used the Garment Pannier 2.0 for 9.5 years, and then it started to show some wear so I purchased the 3.0 about 1 year ago. Recently, the support panels cracked just above the rack hardware, and I've had no success in getting TWG to respond to my warranty claim. When I got the bag, I placed some duct tape over the hardware inside the bag to form a barrier because the 2.0 hardware wore through the lining and ripped one of my jackets. Really hoping they don't try to deny my warranty claim because of that; if they do, then they are not living up to their standards.

Sits well on my bike and great for riding vs. the two paniers I was using before. I will say that it's a little clumsy and difficult to work with. Not sure why two hook loops weren't included to hang the bag. One side has all the heavy suff and one side has the clothing which make it hard to hang your back while getting chaned. Also the small toiletry bag on the top is aways coming unhooked. Never stays in place.

This bike pannier has been fantastic for my commute to my college campus. As a student who carries around a lot of stuff, (notebooks, a gaming laptop, chargers, a bike repair kit, a box of circuitboards, spare clothes) this bag has been a great way to store my gear for the commute and it works well for short walks between classes. Having space to neatly store nice clothes has been a game changer since I need lots of layers to stay warm when sitting in class, but I need somewhere to store them for the commute. I love the integrated reflectors on the bag and the neon yellow rain cover.

Downsides:
I absolutely hate the way the top bag mounts to the pannier. Why is it not just a buckle on each end of the bag? Slotting the pegs into the slots feels terrible to do and they never stay slotted, and then the other side uses a velcro strap through a loop. I've thankfully never lost the top bag but I hope they update that for a later design because its the worst part of this bag.
Additionally the garment compartment has seen some wear, it could use some reinforcing so the inside part of the rack hooks don't rub as much.

My partner is loving the bag. He can put a full suit in it easily, along with everything else (coffee, lunch, laptop, everything else he needs for his workday), allowing him to commute to work on his bike in any weather. He has wanted this for a long time but bringing his suit to work without it getting wrinkled was always a stumbling point. He loves the bag!

I have been commuting daily through rain, snow, and shine using this pannier for 4 years and I can highly recommend it.

Starting with the build quality: The zippers are excellent, the inside face has taken a ton of grit and grime flung at it, and the pack has not worn through where I place it on the ground.

Next the design: I love the thoughtfulness of how the garmet compartment is designed. So easy to hang off a hook and access your towel and change of clothes. I especially appreciate that it came with a wet bag that fits exactly into the towel pocket. Furthermore the other main pockets are just the right size (despite my best efforts to overstuff them) - note I also have a frame bag where I place very thick items like my lunch tupperware, however this would fit in their provided top bag which I don't use. The laptop sleeve has comfortably and securely transported my small macbook air 13" and now a large 16" laptop without issue.

If you are a commuter who likes to change at your destination this is a fantastic purchase and will last you ages! However this is a more specialised item and if you are looking for a large bucket of a bag to carry groceries with I would recommend a different Two Wheel Gear item.
