If you're the sort who camps from spring through autumn rather than just August bank holiday weekend, the Reactor Midweight Liner is a great way to boost the warmth of your sleep system for those chillier shoulder-season nights. Thermolite Pro fabric and stretch-knit construction ensure cosy comfort, adding up to 6°C to your sleep system – which could be the difference between a comfortable night and lying there shivering until dawn. At 350g for the Regular, it's packable enough for backpacking trips, and the armholes with snap closures mean it doubles as a standalone sheet for hostel or hut stays. The technical hood and Free Flow compatible arm openings work with Sea to Summit bags, but it'll fit into any sleeping bag without bunching up. Machine washable, quick-drying, and treated with HeiQ Fresh so it doesn't start ponging after a fortnight on the trail.

What is it that attracts us to the idea of adventure? For Sea to Summit, it’s about freedom and self-reliance – the ability not just to survive, but to thrive in any environment. But although the brand takes its gear seriously, it does so with trademark Aussie humour and blunt, no bullsh*t candour. That’s the way it’s always been, ever since founder Roland Tyson made his first outdoor gear on an old industrial sewing machine in his childhood bedroom back in 1983, at the age of 17. Soon he was designing and manufacturing equipment for other Australian adventurers – and in 1991, he outfitted an unusual first ascent of Everest, in the form of a 1,126 kilometre journey from sea level to the mountain’s 8,848-metre summit. The name Sea to Summit was born.
In 1993, Roland was joined by Penny Sanderson, another Aussie explorer and innovator. Their designs were honed on their adventures, as they spent months climbing, sailing, trekking, overlanding and biking. Nearly thirty years later, Sea to Summit is still 100% Aussie owned and operated, and still putting painstakingly designed gear into the hands of customers worldwide.
