Review on 🚲 VELMIA Triangle Bike Bag - Waterproof, Reflective, and Spacious I Bike Frame Bag for Bicycle Lock, Tools, Jacket I Bike Pouch, Bike Bags with Ample Storage by Daniel Shankle

I can't say anything about the durability, but this bag has been flawless so far. It fits perfectly between the top tube and seat post of my Surly Troll (size S). I stashed the water bottle cage on the seatpost, but the bag fills that triangle to make almost optimal use of space while still allowing me to mount my water bottle on the top two solder points on the down tube while I use the rest. Triangle for a water bottle. I use my bike for city trips and solo multi-day trips with children from the age of 5. This bag is used for the tool kit, first aid kit, COVID mask and general toiletries that should always be at hand. (It really hurts to search the bottom of the basket for splint levers or bandages.) You also don't have to collect these things every time you leave the house. The main compartment of the bag is big enough for a light windbreaker or rain jacket or down vest. The bag is narrow enough not to rub your feet while riding. The straps are very long - I'll probably shorten mine, but the length allows you to attach the bag in many ways. The zips have a nice feel - again, I don't know if this is the first thing to fail with heavy use. Just take a look. I don't know how waterproof it is either.
