I love how easy it is to put on and off my bike. I pack extra tube, co2 cartridges and my multi tool in it. Unfortunately, with all that packed in there during a trail ride on my Trek Marlin 5 MTB the turbulence from the weight inside and riding a trail caused the zipper to open. I lost all of that and had to repurchase an inner tube, co2 cartridge, inflator and multi tool. Learned my lesson and now the I zip tie the zippers together. Small inconvenience for a good product.
