The most common criticism of the Six Moon Designs Starlite backpack is that it's a large pack that lacks an adequate compression system for smaller loads.
After experimenting with stuffing my uncompressed quilt in the bottom of the pack and loading gear that I would normally carry in the outer mesh pockets into the main pack to fill up more of its volume, I settled on an approach that lets me keep my quilt compressed and my gear in the mesh pockets.
The Starlite's compression cord is located on the front of the pack and works by pulling the sides of the pack in toward the middle front of the pack. By angling the two sides toward the middle in this way, the footprint of the pack takes on a more triangular, or trapezoidal, shape. I've found that building a smaller load into a triangular shape against the back panel of the pack works best for me.
Here are some photos to help you see what I'm talking about.
Layer 1: pack liner; compressed quilt loaded vertically in the middle of the pack; rolled mid-layer loaded vertically on the right against the back panel; socks, balaclava, and insulation vest loaded on the left against the back panel.
Layer 2: water bottle loaded on the left against the back panel; cooking kit and food sack loaded middle right; rain shell loaded middle front.
Mesh Pockets: tent fly, stakes, and ground cloth in the long pocket on left; ditty bag in the upper right; water bottle in the lower right.
