The half zipped ones: Their zip goes down to the chest, approximately. You will have to take it off like a pullover. The race to protect our planet needs us all to take part – so we've developed the Nike Move to Zero programme. We recycle plastic bottles into performance sportswear fabrics, giving you hardworking gear that uses less energy and materials to produce. We create premium nylons from re-used fibres. And we're working with our suppliers to build low-impact thinking into every element of our designs. Our ultimate goal? Net-zero carbon emissions, and zero waste. One of the filter options you can use is “Activity”, which allows you to decide which windbreaker is ideal, depending on what you want to do while wearing it. While the majority of our windbreakers are designed for urban life, most of them also work great for sport activities. Furthermore, some are specifically designed for a sport purposes, such as hiking and trail running. They are a very effective protection against wind gusts (it's an obvious one, we'll give you that). Technically speaking, they strongly remove the impact of the wind’s chill factor on you. Meaning you will feel (a lot) less cold because of the wind effect.
