Cocoon Insect Shield Travel Sheet

The Cocoon Insect Shield Travel Sheet is a silk travel liner whose fabric is factory-treated with Insect Shield technology — EPA-registered permethrin bonded into the fibers that repels mosquitoes, ticks, ants, and midges, rated to survive roughly 70 wash cycles. The 100% silk material feels soft against skin and wicks moisture well, so the sheet doubles as a hygienic liner inside a rented or shared sleeping bag and as a standalone lightweight cover in warm weather. At 160 g and packing down to 14.5 × 7 cm, it's one of the smallest items on a packing list, well suited to travelers and warm-climate hikers who need insect protection without the bulk of a full sleeping bag. What it doesn't offer is any thermal insulation or water resistance — it's purely a thin barrier against bugs and grime, not a cold-weather sleeping bag substitute. The treatment also fades with washing over time, so long-term users should expect its effectiveness to gradually decline.
