The streamlined design resists wind while maintaining breathability, ensuring comfort during sustained activity. Whether facing unpredictable British weather or transitioning between seasons, this jacket functions as a versatile foundation piece that integrates seamlessly into any performance-driven wardrobe.
Perfect waterproof/windproof jacket. I am 5" 5, size 6-8 and I opted for a small. Its a perfect fit, I can wear a gilet underneath if I need extra warmth. The details as per Jack1T - fantastic - bungees at the waist to give you a cinched in look. Bungees at the neckline which gives the hood a great fit, added bonus to the hood is it has a little cap peak which looks so cute. I love it no complaints at all. Can't recommend this company enough.
