Down Insulation - The stitching is crucial to the functionality of the insulation because it creates separate baffles (channels) that contain the feathers. Snagged loops and cut threads should be repaired as soon as possible.

Synthetic Sheet Insulation (Nano Puff®, DAS®) - The stitching on sheet insulation holds the insulation in place against a shell or liner. Since the sheet insulation can hold itself together, thread snags and cuts are less detrimental than with down garments. Cutting loose Nano Puff threads doesn't affect technical performance.

Synthetic Yarn Insulation (Micro/Macro Puff®/DAS® Light) - Yarn-style insulation is a hybrid of down and sheet insulation. The yarn clusters hold themselves in place vertically, and the topstitching holds them in place horizontally. Snagged and torn stitching is less imperative to fix than down, but more crucial than sheet insulation.
