Hi cyclists of Mastodon. I am looking for a laptop/messenger bag, with these characteristics:
1. Small, thin and 100% waterproof.
2. Shockproof: strongly padded for protection.
3. On one side, with clips to attach to a pannier rack.
4. On the other side, with two straps like a backpack.
5. One long across-the-chest strap like a handbag.
Does anything like this exist? Thank you!
