Invaluable across multiply activities
I bought these 3 years ago as they are simply the lightest of their kind on the market (200g size L including stuffsac). They are ideal when you are looking to move fast and have very little room to pack. I have been back-packing on the GR20 in Corsica, ran 2-day mountain marathons, and frequently get out on my XC mountain bike, these have proven an indispensable piece of kit every time. Worn over technical pants, Lycra tights, or even shorts, they keep the wind out whilst being incredibly breathable. The lower legs have Velcro adjustment so they can go from normal fitting pants to slim fitting ideal for running or biking. The legs are also slightly articulated with knee darts. The DWR finish extends their performance into light rain showers and unless the forecast is predicting heavy rain these will always be packed instead of full waterproof pants. As long as the activity is high paced then the rain without the wind is not enough to cool you down. The stuffsac is the size of a small apple.
