Ibera G-2 PakRak Pro Panniers Bike Bags (Pair) with Quick Release/Clip-On System - Bike Saddle Bags For Rear Rack Each with 19.8 lbs Capacity - Reflective Saddle Bag Bicycle, Fits Most Racks (Grey)

I really like it. It snaps on it claps on.

Well made affordable easy to install. I’m very pleased so far. Seem pretty idiot proof.

Note: this is for the "Ibera G-2 PakRak Pro Panniers - Bike Bags with Quick-Release System" variant: I have a rear basket. This is my primary storage. I like to keep panniers for overflow needs. My old bike had room to clip normal panniers under the basket. My new bike, not so much. This system ended up being perfect for my needs as the attachment bar for these can be installed lower. The rail was VERY simple to install, and the bags clip on and off the attachment bar easily. I have not actually pushed limits, but I would have concerns over the long term durability and carrying load capacity of the plastic rail and clip setup... I would have paid $15 more for these to have been metal instead of plastic. But for MY purposes where I just want to throw an extra thing of saran wrap for covering drinks, or an extra item or two from the store that doesn't fit in the basket, they are pretty perfect.

These fit amazingly and hold a lot on bike backpacking trips
