So far I mostly use this one for work and I got two other bags with lunch & laptop with me and I gotta say it is not a problem to get my wallet quickly out for the bus or when paying at the cafe with only free hand. I had more trouble with the Piano cause I couldn't close it or open it without two hands due to the zipper.
What I find good is that the bag very steadily rests against my side so I can easily one handed open the string without the bag twisting and turning and even I would not at that very moment tie it again the bag won't "hang open" as least my bag keeps itself closed without a not on the string .
Thank you so much for sharing your opening and closing of the noe. I guess i got to buy a preloved noe to really understand the ease of it.
