It sounds like you're describing a versatile, layered approach to outdoor clothing. Here's how I interpret it:
A "new inside-outside top" could refer to a reversible or dual-layer garment, where you wear a non-waterproof top on one side when dry, and flip it inside out or switch to the waterproof layer when the weather turns wet.
In this design:
Non-waterproof layer: Comfortable for dry weather, offering breathability and flexibility.
Waterproof layer: When the weather gets wet, you flip the garment to expose the waterproof side, protecting you from rain. The waterproof layer also is made from a material to keep you cool in Summer. When it's on the in side.
This could be a very functional solution for outdoor activities, where you need to adjust quickly to changing conditions.
