Review on 🚴 THRLEGBIRD Waterproof Bike Saddle Bag - Portable Cycling Seat Bag for Bike Seat, Large Capacity Storage Bag (1.5L/2.5L/4.5L) - Ideal for Road Bike, Folding Bike by Chris Long

When traveling in groups, I'm often the one who takes the spare parts and repair kit with me. This bag fits two spare hoses, a small pump, mounting hardware, a multi-tool, a small pack of hand wipes, and extra space for snacks. Once on the bike, it only protrudes slightly over and behind the saddle. It appears to be made from the same material that the raincoat is made of, so it looks like it's waterproof. Haven't tested it on a trip yet, but so far I'm satisfied. UPDATE: Driven 34 km with it. Built in everything I needed. One downside I noticed is that the part that connects to the seatpost is quite wide, so I occasionally feel it on the back of my legs while cycling. After a while it's less noticeable, but a little annoying. I'll have to see if it's enough for me to stop. UPDATE #2: Velcro straps allow for more flexibility when attaching this bag. The back and forth gives me the fewest problems when pedaling.
