When mountains get high womens alpine climbing clothing needs to get serious. You need clothing you can rely on whatever happens to the weather. Protection from rain, wind and snow. Women's Waterproof Jackets that are helmet compatible, with skinny tape to maximise breathability and pit zips for ventilation. Insulation and midlayers that keep you warm in the cold and changeable weather conditions, the best synthetic insulation such as Rab's Project Strata range or top end down performance such as Mountain Hardwear's Ghost Whisperer. Women's Alpine Trousers that stretch for movement and comfort and base layers that wick and stay odour free such as Patagonia's capilene range. From experience it's best to have a few very great items of gear because you're going to work them very hard. From brands who take high mountains equally seriously such as Rab, Mountain Hardwear, Mountain Equipment, Patagonia and of course Arcteryx.
