Review on 🚲 Rhinowalk Waterproof Bike Saddle Bag - Quick Disassembly, Rainproof, Under Seat Storage - Professional Cycling Accessories for Mountain and Road Bikes by Darth Calder

I bought these based on a positive experience with the same manufacturer's saddlebags and have not been disappointed. Sized to fit in my roadside repair kit, it offers room without feeling bulky or large on the bike. The included mounting bracket screws on easily by hand and once attached, holds the pack without slipping off and allows for easy detachment and reattachment by pressing the tab. Haven't had a chance to test the waterproofing yet, but the material and construction (no zip, buckle closure) appears to be the same as panniers that have withstood multiple downpours. This is the third seat pack I've tried. Compared to others: Pros: 1) Waterproof construction: As mentioned above, I haven't been out in the rain to test it, but it seems durable. 2) Attachment: Backpacks that attach with straps would slide off my bike when winding. semi-vertical near the seat tube. This stays where it's attached and is easy to remove and reattach. 3) Size: small enough to fit discreetly on my bike, large enough to fit my stuff for every ride (spare tube, patch kit, tire levers, multi-tool, axle nut wrench, valve core schrader tool, small rag, face mask for the COVID-era ) with spare seat. Cons: 1) Not yet. I will update if the waterproofing doesn't work as well as I would like. Other: 1) Not much internal structure: there is a flap with a mesh pocket, otherwise just a space delimited by the outer walls. That's my preference, but those who need pockets and compartments should look elsewhere. Update: I'm still happy with the backpack after a month and the contents stayed dry during moderate rain and downpour rides.
