Review on BV Bicycle Y-Series Strap-On Bike Saddle Bag/Bicycle Seat Pack Bag, Cycling Wedge with Multiple Size Choices by Nate Nelson

The zipper is now difficult to open. I noticed that it was clogged with threads protruding from inside the bag. I had to turn the bag inside out and cut off the loose material to keep the stitching from unraveling completely. Now the flash works again. I love this design. Love the way the straps fold over the seat rails and attach to each other. The hard plastic insert keeps the shape of the bag. The Y series looks better than the standard series, but as others have pointed out, the taillight slot doesn't position the taillight properly. My taillight popped out of a fabric slot while riding the RR tracks. My three foot chain and padlock fit in a medium sized bag. The tiny amount of reflective material is almost ridiculous.
