Ultra lightweight and simple, the Astro™ Lite offers a plush 3.5-inch thickness, a premium fabric suite, and lateral baffles. The 20-denier fabric shaves valuable grams without sacrificing comfort.

The origins of Sea to Summit began in 1983 in Perth, Western Australia - a time when lightweight, outdoor products were hard to find in Australia.
