Pretty solid.
So far I’ve hauled all my little bike doo-dads in it and I went to the store and managed to fit 3 big rolls of packing tape in it for the ride home. We aren’t talking adventures here yet, just living life. It seems to be built very well.

I ride a 2011 Motobecane Team Fly 29r, and wanted to get my water pack and tools off my back. The coyote color matches the ti frame well. It is a little long for the size large frame opening. It easily holds my 2 liter water pack, pump and tools. I really like the separate zipper compartment for phone and allen keys. Construction is very good and I expect the bag will last a long time. I have replaced every component on the bike except the seat post and I think the bag will last as long as the frame. I will need to buy a longer tube for my water pack. After the initial rides I'm very happy with this product.

Really happy with this frame bag! It fits neatly on my bike and adds useful storage without looking bulky. The construction feels solid, and the simple design is exactly what I wanted. I especially like how it leaves room for my water bottle, and the pink logo looks great with my frame.

Not water proof, found my electronics floating

Amazing
