Just like the tires on your bike that are designed to take anything (practically) the road has to offer, this bag is tough! It's a good size, not too big, not too small. The handle is right-sized and smooth to the touch. The bag also holds form and doesn't flop like many typical toiletry or tool bags. The zipper is good quality too. I also like how the blue pops off the black rubber. Great product all around and very likely to get another.
