Very satisfied so far

4 years ago

I've used this only twice so far, but feel I have useful info. I used it's max capacity, and personally, I don't think I'd want any more attached to my seat/post. So, for me it's an ideal size. Also, I'm already aware of the benefit of having packs that can easily be removed/attached to bike. At front I had my hybrid spongy/inflatable pillow, then surrounded my liter size bag with my tent (no poles, fly), and at the opening end the tent footprint. I like how everything functions and feels sturdy and secure. The adjustable stretch cord on top is nice too.

Great solution for extra storage!

5 years ago

I really like this bag. It is a good solution for a carbon bike that you don’t want to put racks on. It easily holds my tube, air, tools, lock and room left over for coats and food.

Good for Bike Camping

4 years ago

It is a very well made, thoughtfully designed way to carry a lot of your stuff in a compact space. If you are a bike camper, you would find it a nice accessory. I am an urban, ride around the neighborhood kind of rider mostly. I do 20-30 mile rides on The Bay Trail, so I was looking for a pack to carry a sandwich, snacks, my camera- so, for me, the bag is like having a Tractor Trailer when all I need is pickup truck. Not a criticism, it's just not designed for the riding I do.

Awesome bag

4 years ago

This bag is absolutely fantastic. We packed extra clothes and some toiletries and took a much needed 3 day bike trip. The packs are well balanced and securely fastened to the seat post. It was amazing how much they could fit. I definitely recommend this product!
