Keep Your Pillow Under Your Head, simple enough. It's the middle of the night and you're awake again out camping. Your pillow slid off your pad again, your neck is stiff, and you're spending more time readjusting than sleeping. All too familiar, right? Here's the thing. The biggest reason you wake up at night while camping isn't the frog hopping on a leaf by your tent. It's your pillow. And the thing Big Pillow doesn't want you to know? You don't need a new one. What you need instead is to keep your pillow under your head and strapped to your sleeping pad. This is exactly why we created Pillow Strap. Pillow Strap is a trifold pillowcase made of a soft, super stretchy fabric that holds your camp pillow securely to your sleeping pad all night with an adjustable elastic strap and buckle tensioner. It's an ideal upgrade for both sleeping bag and quilt users. The Pillow System That Adapts to How You Sleep Need more height or softness? Pair it with a puffy jacket or extra piece of clothing inside the enclosure and dial in your preferences. Everyone sleeps differently and Pillow Strap gives you the flexibility to design the pillow support you need and hold it all together in place. It works for everyone, side sleepers, back sleepers, and even rotisserie chicken sleepers. Your pillow stays right under your head where you need it. You can even slide your hand under your pillow for that cozy at-home feeling.
