Review: Extremely well made - I’ve been searching for this type of bag for a long time. The West Biking Rear bag is just the right size, not too big but large enough to carry a day’s riding essentials plus outer elastic tie down and bottle holder. It stays put on the rack and doesn’t slide around at all. Great bag 5 stars
Review: Great Bag - This was delivered about two minutes before I went on a 10 mile ride. I put it on and loaded it up in about 3 minutes. I thought I may have over loaded it, but didn't come close. I've got a full 26 oz Yeti, my bike lock, large battery pack with cables, a micro fiber tool and my bike tool kit, with room to spare. The bag is pretty sturdy too, kind of like a hard shell but soft touch rubber case with a nylon flap with rubber covering the zipper. I'm fairly impressed and I'd reccomend it for anyone in the market for a cargo bag for their bike.
