Cotton vs linen vs synthetic fleece: Natural fibers stay cooler for beach blankets

Cotton and linen breathe and stay close to ambient temperature, while synthetic fleece and microfiber trap heat. A lightweight Turkish towel (pestemal) is a good alternative—thin, fast-drying, and non-crispy. For extra cooling, try a blanket with reflective aluminized backing. Honestly, a folded bath towel works fine too.
