Our TravelSheets are infused with Insect Shield technology, a revolutionary treatment that creates a breathable fabric while safeguarding you from insects. Insect Shield technology uses an Epa-approved application of Permethrin, bonded at a molecular level, to deter insects effectively for up to 70 washes. This innovative treatment offers proven protection against mosquitoes, ticks, ants, flies, fleas, chiggers, and midges (no-seeums), many of which can carry harmful diseases like malaria and Lyme disease. Colorless and odorless, Insect Shield provides protection without the need to apply chemicals directly to your skin, making it a superior choice for outdoor enthusiasts.Embrace the best of both worlds with our TravelSheets. Made from fine yarn using a special weaving technique, this high-quality Pima cotton fabric is both lightweight and durable, creating a natural vapor balance that is breathable and incredibly comfortable against your skin.
