I really like the choice of straps to secure the bag to my bike. I used the 4 individual straps with looped ends. Each 1 could be anchored to my bikes luggage rack and the bag easily clipped on and tightened down, a really good feature of the bag. The fabric quality is lovely but the top must be rolled at least half a roll to stop rain water leaking through the zip. The shoulder strap is sturdy and it is comfortable when carried on the shoulder. The 2 compression straps at each end of the zip do a good job of hunkering the bag down. I'd recommend this bag.
