We aren’t talking about a fancy dress onesie, we are talking about a custom made, down filled, weatherproof onesie. A onesie warm and protective enough to keep you alive in the most severe alpine conditions on earth.
In 2013 mountaineer and Mont Ambassador Chris Warner came to Mont with a request; an outfit to assist him on his ascent of the highest peak in the Karakoram Range, the volatile and demanding K2.
Mont designers knew there was going to be nothing funny about this onesie.
Let us take you on a tour of the user-focused Mont design and manufacturing process at Mont HQ in Canberra, Australia.
Chris wearing the first sample made from basic measurements previously taken of him.
After getting a feel for the suit, Chris gave his feedback on the form, function and fit. Adjustments to the pattern were made, and the real suit production begins.
The pattern pieces are expertly cut by Danny from a roll of waterproof, windproof, breathable Hydronaute XT fabric.
Mont machinist Saun constructs the intricate shell of the garment. The shell includes articulated elbows and knees for ease of movement, reinforced ankle cuffs, knees and seat, down filled draught tubes to seal gaps in the zip, elasticated cuffs, internal and external pockets, lightweight mesh to divide down chambers (baffles) and drawcords to seal off all possible escape of warmth when the temperature dives.
Each down chamber or baffle in the empty shell is filled with calculated weights of pure goose down with a minimum loft rating of 800.
Trims, zips and drawcords are added to complete the garment. Inset: Mont Pattern Maker Kaleen makes some measurements to check everything is in order.

In a world that moves fast, finding time for adventure can feel impossible. But what if the solution isn’t in grand expeditions, but in small, intentional escapes? Micro-adventures—overnight or short trips into nature—are the perfect way to reset your mind, recharge your body, and reconnect with the wild, all without taking time off work.

The rugged beauty of the Tyndall Range, with its towering conglomerate peaks and dramatic cliffs, offers some of the most thrilling and scenic climbing in Australia.
It just might be the most beautiful climbing venue in Australia.
