Description

The Nautilus offer exceptional waterproofing and breathability, keeping your legs dry on the steepest and soggiest of hillsides.

  • Reliably waterproof and breathable (20K/20K) 3-layer fabric
  • Super durable 70D nylon 6,6 outer with reinforced hem and ankle patches
  • Designed for striding with articulated knees and a gusseted crotch

The Nautilus use a specially developed 3-layer fabric treated with a PFC-free durable water repellent. The fabric's construction provides reliable, long-lasting performance, and maximum reassurance when you’re bracing for biblical levels of rainfall.

Designed for dynamic movement with articulated knees and a diamond-shape gusseted crotch, the Nautilus are waterproof trousers you can be comfortable in, even on airy scrambles. A slimmer lower leg eliminates excess material (and perpetual flapping in strong winds) and there’s a little bit of give to the fabric for high strides.

We've used an exceptionally tough 70D nylon 6,6 outer fabric for season-after-season heavy usage. And we’ve also reinforced the hems and insteps to provide extra abrasion resistance in high wear areas. If you venture onto frosted ridges and frozen wind slab, the stiffened instep patches are also harder to catch on crampon spikes.

A semi-elasticated waist with zip-fly and button-closure provides a secure fit, makes your trousers easier to get on and off, and helps with sudden calls of nature. The three-quarter length two-way leg zips fit easily over bigger boots and enable easy venting on more vertical inclines. And the zips themselves are water-resistant with internal storm flaps to keep out driving squalls.
