Aeros Ultralight Pillow Large by Sea to Summit - ideal for ultralight adventures. The Aeros Ultralight Pillow Large is an exceptionally lightweight and space-saving pillow for on-the-go use. The soft, brushed material made from recycled polyester feels pleasant to the touch, while the contoured shape fits into the hood of your sleeping bag. To keep the pillow in place throughout the night, the wavy bottom and the included PillowLock system provide stability. It can be quickly inflated through the Mini XPRESS valve, allowing for individual firmness adjustment. With a height of 12 cm, it offers comfortable support for the head and neck. The robust, hydrolysis-resistant TPU makes the pillow durable. When packed, it is barely larger than an egg, making it ideal for trekking, traveling, or other adventures with lightweight luggage.
