Skyllen Oversized Waterproof Raincoat

The waterproof rating of a jacket or coat is measured by the hydrostatic head test, which tests how much water the material can withstand before it starts to leak. The higher the rating in mm, the more waterproof the garment is.​

5,000mm waterproof rating

The majority of our Seasalt Rain® products have a waterproof rating of 5,000mm. This means the jackets or coats are waterproof and ready to keep you dry on wet, windy days.

3,000mm waterproof rating

A small number of our outdoor jackets have a 3,000mm waterproof rating. These are lightweight jackets, like the Pack-It Jacket, suitable for unexpected showers and changeable days.

High quality, breathable raincoats are designed to let water vapour from heat and perspiration escape the fabric, helping reduce condensation and overheating.​

Breathability ratings are expressed in g/m², which relates to how much moisture in grams can pass through a square meter of the jacket’s fabric over the course of a day. The higher the rating in g/m², the more breathable the fabric is.

5,000g/m² breathability rating

The majority of coats in our Seasalt Rain® collection have a breathability rating of 5,000g/m². Meaning they are perfect for everyday use or longer walks that require a little more exertion.

3,000g/m² breathability rating

A few of our lightweight Seasalt raincoats, like the Reversible Raincoat, have a breathability rating of 3,000g/m². These raincoats are ideal for lighter activities such as a stroll to town or short walk on the coast.​
