I will for sure keep adding to this list. I already have some in-mind.
- Cut-out wick-reducing AIO - follow-up and stay-dry follow-up.
- Sized pocket AIOs
- OS and multi-sized pocket AIO
- Basic sewn-in soaker AIO - also can be used fully sewn-down as shown with my trainers.
- Dual soaker / Freetime-style AIO
- Elemental-style AIO - just make or use a Flip-style cover, and add in the Elemental-style soaker.
