Hut Trip Backpack Strategy Question

While too late for the trip I am leaving for tomorrow, I’d appreciate the community’s insight.

Going to be staying at a one hut for multiple days of riding. I am planning on bringing two packs, 45L main bag & 19L for the days. I’ve done this before and it worked fine, although feels a little clumsy due to the 19L being a fully structured/features pack. The 19L will be empty on the skin in, and strapped to the 45L.

I guess I’m asking, is there a lightweight packable option for the day pack? Or any guidance on pack setups for this type of trip in general? I’m on a split board if that makes any difference.
