Lightweight and compact air pillow with a geometric design. This is the UL Air Pillow. Although it's UL (Ultralight), it boasts high functionality, such as a suede-like backing that prevents slipping and a one-way valve that prevents air from escaping. In mountain camping, it expands the effective area of your sleeping mat, allowing you to cover your feet even with a shorter mat. I'm of the opinion that using a pillow is better because it makes a huge difference in how tired you feel the next day just by supporting your neck, but I didn't want to add to my luggage... This is the product I was looking for. - Brand: Sea to Summit - Model Name: Aeros Pillow Ultralight Regular - Color: Gray - Design: Geometric pattern - Storage Size: Compact storage - Type: Air pillow Thank you for viewing.
