If you're passionate about venturing into the great outdoors, then you'll know how quickly perfect sunshine and brilliant blue skies can turn into lashing rain and fierce winds.

Whether you're an avid adventurer, dog walker or country rambler, waterproof clothing is absolutely crucial in keeping you dry and protected when the weather turns.

However, what many tend to overlook is the importance of waterproof ratings, and how these ratings are not only tailored to water exposure, but to specific environments, activities and weather conditions.

For example, at Waterman's Country Supplies you may have seen waterproof jackets with a 25,000mm waterproof rating or trousers with an 8,000mm rating to indicate the amount of water a fabric can withstand when exposed to a column of water before a leak occurs.

Simply put, the higher the waterproof rating is in millimeters(mm) the more waterproof the fabric is proven to be. Usually, waterproof fabrics are tested and rated using the hydrostatic head test.

Having the correct waterproof rating information to hand is vital. It'll give you the precise waterproof protection guidance needed to shield you from the specific severity of weather you'll be facing - from light drizzle and normal rain conditions to heavier rain, snow and extreme weather.

Also, if you get yourself familiar with waterproof ratings, you can make more informed budgetary, technical and style-based decisions about the waterproof clothing you're purchasing.

For example, if you're only likely to be stepping out into light rain, it makes sense to shop according to the waterproof rating you actually need instead of overstretching yourself with an unreasonably high rating and a more expensive garment.

Waterproof Ratings - Explained

  • Up to 2000mm: Water resistant (very light rain) - town and city travel, commuting, short leisurely walks and shopping trips.
  • 2000mm - 5000mm: Waterproof (light to normal rain) - everyday use, longer commutes, casual outdoor activities like quick dog walks and short walks into town.
  • 5000mm - 10,000mm: Highly waterproof (medium to heavy rain and moderate snow) - suitable for longer outdoor walks, hiking, rambling, trekking, walking uphill and extended time in the countryside. 
  • 10,000mm - 20,000mm: Extremely waterproof (heavy rain exposure and wet snow) - suitable for long walks, hiking in the mountains, coastal walks and extended exposure in very rainy weather conditions. 
  • 20,000mm & Up: All-day waterproof protection (high water pressure, heavy rain and snow) - can be used all day in all weather conditions, even if you're carrying a heavy backpack.

For example this Coldstream Huntford Waterproof Jacket has a maximum protection rating of 10,000mm waterproof level.

Also having waterproof zips, this 0g fill jacket is the ultimate summer jacket for training and for wearing whilst on the yard. The innovatively developed hood is magnetic which means it stays in place whilst riding but easily accessible when required or can be detached. Sophisticated Coldstream branding adorns the piece with a raised icon on the sleeve, silicone icons on the velcro sleeve strap and vertical branding along the zip and spine. 

Our highest rated waterproof jacket, at 20,000mm is the Hoggs Ballater Classic Waterproof Green Highland Field Jacket.

It is the highest performing technical garment Hoggs of Fife have ever created. Featuring an impressive waterproofing to 20,000mm Hydrostatic Head in tests, it is also breathable to 10,000mm and comes with a Teflon finish for added stain protection, preserving the look and feel of the jacket.

You'll also get a two-way SBS waterproof metal zip, an array of pockets and attractive suede detailing. This is a must-have for any sportsman looking to stay dry and protected in the field, out in the countryside, or those looking to brave harsh weather conditions with confidence.
