my chrome bag is about 5 or 6 year old now and still going strong as ever – waterproof as anything. The seatbelt style of the buckle is the best for fast on/ off adjustments
I just put my work laptop in a sleeve inside the main bag – loads of room for shopping etc. i have had some crazy big packages etc in it
I recently got a timbuk 2 x-small for when I just want to carry my d lock/ a book/ gloves/ lights/ whatever. It’s fine but compared to the quality of the chrome it’s like a toy. And the top of the bag “gapes” open a little – meaning water would almost certainly get in in a downpour. Seems like careless design to me. The buckles, clips and method of adjustment feel over complicated and flimsy compared to the chrome as well
