The Ironside Waxed Sherpa Fleece Jacket Pre Order




Pre Order Ships: Mid/End December

The story of waxed cotton begins on the high seas …… Sailors in the 15th Century were at the mercy of the rain, wind and waves and often their craft offered little protection from the elements. Survival was dependant on good clothing. British Sailors treated their flax canvas sailcloth with linseed oil, which prevented the sailcloth from becoming soaked, keeping it light and efficient in the strong winds. Left over pieces of oiled sailcloth were often crafted into crude smocks and worn by the men on deck to protect them from the harsh biting winds and sprays.

However, Linseed oil was far from ideal, turning yellow over time and cracking in cold conditions, losing its weather-resistant properties. British Millerain, already at this stage an established cotton finishing company, set at work to overcome this problem and pioneered the development of paraffin-based waxed cotton, which offered improved weather-resistance and breathability, without the deteriorating properties of linseed oil. This early work formed the basis of waxed cotton as we know it today!

For this drop of Ironside Jackets we chose a 12oz British Millerain waxed cloth which offers substance and mobility. Aesthetically, waxed cloth distresses over time and develops a soft sheen reminiscent of a well-worn leather.

Fully cut and sewn in Los Angeles with the strongest poly-core cotton thread this jacket is built to last. Even though functionality is the core design motivation, there is a stylish, yet understated ruggedness that elevates the sherpa jacket to the pinnacle of timeless American design.

Buy true to size for regular fit and if you plan on layering with flannel then size up.

Now available in XXXL sizes as well - don't sleep on this one...
