I am in love with my Packing Cube Shoulder Bags in Everyday (200d Dyneema®/nylon).
They are the most versatile bags either by themselves on as bags in bags.
By themselves they are great shoulder bags (with the Shoulder Strap), waist bags (with the Waist Strap), bike bags (with Key Straps),
As shoulder bags they can be converted into minimalist photo/video/audio bags, a perfect and lightweight addition to the Field Journal Notebook for birders as well as other wildlife and nature enthusiasts, journalists, anthropologists and lovers of urban landscapes.
It is perfect as a vacation bag for snow birds.
For a relaxing day at the beach, it holds a paperback or Mini iPad sized electronic devices, sunglasses, hat and other sundries.
For foodies, it is so lightweight that it can conform to belly size fluctuations after paella, gumbo, gelato or beignets feasts.
For biking, hiking and boating explorers, it is a really useful and lightweight "throw the essential stuff" bag (snacks, first aid, GPS/map backup/survival blanket/Guardian Dual Function Light/Tri-Power Safety Whistle)
They are great inside zippered compartments in Swifts and Shop Bags.
And of course they are great Packing Cube in all the Travel Bags.
Tom's pictures in the mountains, with the new 400d Dyneema®/nylon and lighter Dyneema Synapse as well as Jannielee UV Synapse in Iceland gave me the idea of asking for a Packing Cube Shoulder Bag with #8 YKK Aquaguard® water-repellent zippers.
They would enable the people who want to visit or live in snowy and/or rainy places to wear the Packing Cube Shoulder Bag on it's own in all conditions.
This is such a great bag/packing cube, it needs 400d Dyneema®/nylon with #8 YKK Aquaguard® water-repellent zippers siblings for our water logged adventures.
Note that Londonrain, Amsterdamrain, Parisrain, pretty much everything on top of the 50th north parallel, including hourly changing weather Alaska, as well as moonsoon, sudden thunderstorms regions, all over the world, have to deal with, the very beneficial to landscapes and crops but deadly to electronics, not welcome on fine silks or wools and positive spoiler of lunch in ecologically friendly but non waterproof boxes, H2O.
