Not only is this parka waterproof, wind resistant and seriously durable, it s also made using recycled fibre from around 23 plastic bottles. Compared to making what s called virgin fibre, recycled fibre offsets using new fuel, emitting fewer greenhouse gases and conserving water and energy in the process. That makes a big difference for our future.Here s a closer look at just some of the reasons why you ll love it... Waterproof heavy downpours? Bring them on! The back of the fabric is coated to repel moisture and the seams are sealed with a special machine to stop water entering through stitch holes. Durable It's made with the highest quality materials from the best mills. These fabrics are woven to last and to protect you from the elements Wind resistant the fabric is woven and coated in a special way. This makes it wind resistant, keeping out chilly breezes to help you enjoy the open air. Breathable the outer layers are breathable, keeping you warm and dry but also letting the air escape. Reproofing a waterproof jacket recommend you reproof our jacket a couple times a year dependant on its usage. This is due to the nature of the coating which becomes less effective over time as it is affected by dirt and abrasion. Suggest you keep your waterproof clean and reproof it periodically to keep it feeling like new. How to tell if it s time to reproof: the best way to test your jacket is to pour some water on it. If it is working effectively, the water will bead up into droplets. If it has degraded, the water will soak into the top layer of the fabric and wet out , making the fabric look darker. If this happens, it s time to reproof. For light usage, you should expect to reproof your garment 2 3 times per year. If you use your waterproof for intense exercise (hiking, biking, running or climbing) you should expect to reproof more frequently. Treatments: There are lots of different products on the market which can be bought online or out outdoor retailers for your reproofing needs. Nikwax Tech Wash and Grangers are great products which can be washed in or sprayed on following their instructions.
