I like the versatility of the 26. I added an encasement for it which has handles and a shoulder strap and I like using it better than my Speedy 20 because of the larger opening. I use the 19 to store my prescription glasses and sunnies in their soft cases in my backpack so that I don't have to dig around for them. I have yet to use the 15. I'm sure I can find a way to use it. I'm a maximalist and carry a lot of things with me.Just wondering how do people use these pouches on a daily basis? or do you only use when traveling? they seem practical for everyday use but I cant think of something to put in it hahhaha
