Tapered Mummy

The narrowest of our bags, it eliminates ‘dead space’ making it as thermally efficient as possible. This cut generally means that the bag rolls with you while you sleep. Although compromising on space, this shape will maximise performance and keep pack size and weight to a minimum.

For mountain marathon runners and committed alpinists who need to travel light, the Mythic Ultra 360 is a game changer./

Built from lightweight recycled 10D Atmos™, it uses Thermo Ionic Lining Technology (TILT) to coat the fibres with titanium, helping reflect radiant heat back towards your body without compromising the fabric’s breathability. While that reduces the amount of down required for a given level of warmth, the angles of the bag’s trapezoidal boxwall construction also improve the evenness of down distribution, eliminating cold spots.

Filled in the UK with 900FP down and weighing in at just 645g, the Mythic Ultra 360 provides one of the most efficient warmth-to-weight ratios available.

Weight saving baffle construction, preventing down shift/migration
Trapezoidal boxwall construction, to maximise loft and warmth
Proportionally designed differential cut
Anti snag bonded zip guard
Ergonomically designed internal collar and hood
Angled foot box for relaxed sleeping posture
½ length YKK® 3 coil main zip with noctilucent puller
