Six Moon Designs Swift X
The Swift X is the X-Pac version of Six Moon Designs' Swift, using the same Delrin hoop frame as the Swift V but in a waterproof laminate. At 38.8 oz it is heavier than most packs in this segment, which is the cost of the hoop and the fabric.
Price and availability on Six Moon Designs’s site may differ.

Osprey Exos Pro 55

It uses NanoFly, a 100D nylon crossed with 200D UHMWPE, over a 3.5 mm LightWire frame, and saves nearly a full pound against the standard Exos 58 at the cost of load rating and a fixed hipbelt.
