Vernon bike trunk bag
Purchased to replace a 15 year old Nashbag served me well until the main zipper gave out and is No longer available. This new bag attachment is the same using Velcro straps, the bag zipper look’s greatly improved, this one has more space and useful compartments. Shipping was fast and the price was good.

United StatesWell-made Very Water Resistant
I love this bag. I’ve had it for about six months and have used it in multiple downpours (Seattle winter) and it keeps my items dry. It’s usually stored under my desk at work, so it gets kicked around a bit and it still looks good. Love the multiple pockets and roomy enough for two pairs of salsa shoes, water bottle, and a lightweight jacket. The only thing that I’d like different is for it to be a little wider on top. This would allow me to transport my laptop safely in its own case.

United StatesI love this bag
I use this every day on my commute to work. It holds everything, like my lunch, keys, building ID, iPad and phone, with plenty of extra room. I can easily connect and disconnect it from my rack very quickly. A pure joy to own, and it is very well made.
