Circuit Down Sleeping Bag -9C|15F Sea to Summit Sleeping Bags

Circuit Down Sleeping Bag -1C|30F Sea to Summit Sleeping Bags

Built for the nights when -1°C won’t cut it

It’s easy to underestimate how cold a night in a tent can actually get once the sun disappears for good. The Circuit -9°C carries the same clever design as its milder sibling – semi-tapered-rectangular shape, wrap-around anti-snag zipper, continuous down draught tubes and hybrid box baffle construction – but with considerably more 650+ fill Ultra-Dry duck down packed in to handle serious cold. An internal zipped pocket keeps your phone or head torch warm and within reach, preserving priceless battery life without the need to bury it somewhere at the bottom of the bag. It’ll still open out into a quilt if conditions warm up unexpectedly, so you’re not locked into one mode for the whole trip. Ultralight 20D fabric keeps the pack weight sensible despite the extra insulation, and the whole thing rolls into its own compression sack (and storage cube once you get home).

Sustainability through longevity: Sea to Summit designs and builds gear that is meant to be put to the test, wherever your adventures take you. Sea to Summit guarantee this product against defects in materials or workmanship for the expected lifetime of the product.
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.
