Unbeatable bag for car-campers and vanners

The name on this one is slightly misleading, because while the Trek makes a decent backpacking bag for shorter trips, it’s actually designed for camper-vanning and car-camping. In fact, it might just be the perfect all-round vanlife bag. The secret is in what Sea to Summit call a ‘semi-rectangular’ fit, which gives you a much roomier bag than the usual hiker's coffin while still keeping the packed size down to a Kombi-friendly 18 litres. Add in their versatile 'Free-Flow' zip system – which combines two side zips and a separate footbox vent – and you've got an incredibly comfortable and versatile bag. With a lightweight recycled polyester shell, the fill is 650+ fill power duck down, offering a good balance of price, warmth and weight. An added bonus is Sea to Summit's superb 'Ultra-Dry' down treatment, which means the bag will stay warmer when damp, and dries out 60% faster than standard down. This women's version features a more female-friendly fit, plus extra insulation to allow for the fact that women often sleep a bit colder.

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.
