Never doubt the importance of one humble square of fabric on your list of essentials, especially when it looks and feels like this one. Pistil’s soft, breathable Delaney Bandana is made of 100% cotton and adds a springy pop of color to even the darkest, “least-explored” corners of your closet. Wear it as a gaiter, headscarf, necktie or headband to head off searing sun, stinging sweat or icy A/C. When you wander off the beaten path, use it as a trail or campsite marker, sling bag or even a tourniquet in a pinch.
