Originating from Perth, Australia, the brand Sea to Summit has been offering products dedicated to outdoor adventures since 1990. The story begins with a solo ascent without oxygen from sea level to the summit of Everest. From sea to summit! Since then, the brand has cultivated a culture of perfectionism and emphasizes the design and functionality of its products designed for camping, hiking, climbing, and water sports. With a cutting-edge research and development centre, Sea to Summit offers lightweight, high-performance gear ideally designed for all outdoor enthusiasts and travellers seeking escape and adventure. Among these products, the Aussie company particularly stands out for its inflatable mattresses that are featherlight, warm and compact sleeping bags, and practical equipment for camping kitchens.
To produce adventure gear that brings you closer to nature, the Australian brand does not hesitate to test its products in real conditions. This is surely why the Sea to Summit mattresses are so high-performing. The Ether Light XT mattress ensures a perfect night's sleep, no matter the situation. 10 cm thick, it is designed from the Air Sprung Cell welding model, where the cells are interconnected but independent. Thus, each compartment deforms independently so that the mattress adapts to the shape of your body. In addition to being comfortable, this mattress is also incredibly light and takes up very little space when folded. Paired with a Sea to Summit sleeping bag, you are sure to have a night like at home. The Ascent AcII down sleeping bag, featuring natural insulation, adapts to all situations thanks to its triple zip that allows you to maintain excellent thermal insulation in cold weather or, conversely, to promote ventilation in warm weather. Light and compressible, this sleeping bag is a must for all your adventures, from hiking to van trips.
To ensure that all adventures are ideal, the brand offers a whole range of products and camping accessories that greatly simplify life. Among them are the Sea to Summit pillows, which provide that little extra comfort that can be so lacking during nights under the tent. For summer nights or for hygiene reasons, the Australian company designs high-quality liner bags. The Sea to Summit sleeping bag liners, like the Thermolite Reactor® Extreme, provide a bit more warmth during chilly nights. In a refuge, they are perfect under a blanket. And once folded, they take up very little space for a negligible weight! Also focused on kitchen accessories, Sea to Summit develops a whole range of cutlery, mugs, pots, and tableware dedicated to hiking. Among this Sea to Summit camping kitchen gear, the foldable X Mug Pliant is perfect for hiking and trips where space is a luxury. To store everything, the brand develops bags suited for outdoor activities. Perfect for protecting your belongings, the Sea to Summit dry bags are to be used for both water outings and wet adventures.
