Review: Durable and reliable - Love the roomy bag. Holds all essentials for a ride. Well made and good value for the $$
Review: Good quality bike rack bag! - This well-made bag has come in very handy. I usually ride my bike to a local restaurant for lunch. I put ice packs, drinks, and storage containers in this for the trip over and fill up the storage containers with leftovers for the trip back. On our last trip, we stopped at the grocery store for a few items (steaks, heavy cream, 2 packs of frozen raspberries to name a few) and this bag held everything we needed.

### ⭐⭐⭐⭐⭐ Durable and reliable
*by J***G on December 18, 2025*

Love the roomy bag. Holds all essentials for a ride. Well made and good value for the $$

### ⭐⭐⭐⭐⭐ Good quality bike rack bag!
*by D***N on January 4, 2026*

This well-made bag has come in very handy. I usually ride my bike to a local restaurant for lunch. I put ice packs, drinks, and storage containers in this for the trip over and fill up the storage containers with leftovers for the trip back.

### ⭐⭐⭐⭐ Good product overall.
*by S***H on August 9, 2025*

Love the size, the small side panniers, extra bottle holder and all the well made components. Love the rain cover, too. The attachment straps didn't quite line up perfectly with my Trek ebike rack, but I think it will be stable as I bike more with it. One suggestion is that it needs the velcro straps to adjust to narrower racks...I had to wrap the strap around to make it shorter to stick.
