My luxury item is an REI flash 22L. It’s .14oz, but super comfortable. From an UL standpoint it’s heavy, but the support and padding is a lifesaver compared to lighter day packs suck as the Sea to Summit Ultra Sil that people recommend. If you’re using it as your summit pack, Sea to Summit is probably all you need, but if you are backpacking out to a campsite and then doing day trips from that site to other places the REI Flash may be your best option
