i used this handlebar bag during my last overnight backpacking trip. i filled it with rain gloves, a jacket, and lots of extra clothing items i figured i would need quickly while riding. the bag withstood hours of rain and had no leaks. it looks good and it is not bulky or heavy. i have kept the bag on full time. minor cons...The rain flap will stand straight up as you ride with speed/ downhill and I need two hands to unzip. there are loops on the side that i need to hold while unzipping.
