Review on Waterproof Motorcycle Luggage Bag - BORLENI Motorcycle Dry Bag for Skiing, Travel, Hiking, Camping, Boating, Riding, Fishing (Black/Red, 25L) by Jeremiah Vishwasrao

We haven't used them on bikes, we've used them on Thule trunks. We had two bags with many things. The bags compress well and appear to be water resistant (no rain or water to test). We combined the straps and tied other things. They have been transported and unpacked several times and after 3 weeks on the road they are no worse. I only gave 4 stars because I could imagine some problems with the water if the rain is heavy enough. Definitely recommend these bags.
