Sea to Summit Ascent Down Sleeping Bag

Sea to Summit is a globally recognized outdoor equipment brand founded in Perth, Western Australia, in 1990 by Roland Tyson and Penny Sanderson. The brand was born from a passion for lightweight, high-performance gear suited for extreme conditions, inspired by Tyson’s own experiences crafting equipment for Himalayan expeditions.

Today, the brand's headquarters remain in Australia, where design and innovation take place. Manufacturing is primarily localized in specialized facilities across China and Southeast Asia to maintain high technical standards for their waterproofing and insulation technologies. In 2022, the Australian private equity firm Five V Capital acquired a majority stake in the company, ensuring its growth and distribution continue across global markets including North America and Europe.
