The Marshall jacket benefits from a bespoke fit unlike any lightweight sports jacket in the market. The arms are cut to sit close to the body whilst maintaining sufficient ventilation with the torso demonstrating a slightly more relaxed fit to allow multiple layering. We advise it fits true to size. If you are unsure on your size please email info@castore.co.uk and we will respond within 60 minutes.​

    Very nice The jacket is perfect for the times where the temperature is between 10-15 degrees C. Which in Sweden is almost all year round. It fits nicely and doesn't make you sweat.

    Best rainjacket ever For the first time after 20 years of outdoor running/training: both warm and comfortable - simultaneously!

    A real win for sure Bought this as a follow up to my Rix jacket. I have used my past one a lot and this one is warmer and even more comfortable. It feels light, the material has great water resistance yet feel lovely and softer. Fit is standard to the classic.
