I love this bag! It's so cute, very well made, very roomy. Attached easily to my rack. Will hold my big stainless water bottle, snacks--whatever else I might need to carry when I ride.

fits my bike rack perfectly and stays very secure while riding. I got the black floral and it's so cute. Lots of pockets and compartments for ALL my things. Great for my meal pickup orders :-)

Loads of room and pouches. Love the design. I have been using it for 3 months and for its size it holds a lot. I put my cell phone in a very safe pouch with a zipper. If there is not a enough room to fit my jacket inside I use the outside bungee cord. I only had to do that once when I bought 3 ears of corn from a farm stand and put them in the bag. I am very satisfied and the pattern makes it personal to me . It matches my silver with a light lavender iridescent tint perfectly.

Fits perfectly on my new eBike rear bench rack and the style, compartments and that floral design is exactly what I was looking for! A quality bag for sure. Love that floral design. Maybe have more floral options for folks in the future? They will sell like hotcakes. Super nice!

Loved this roomy, well-made bag. It's a fantastic value. Only reason I returned it is because the flowers were more of a salmon color and I needed pink for the look I was going for. (Almost kept it anyway!)This trunk bag is an excellent value. Go for it.
