Mens Protean Waterproof MTB/Downhill Shorts

The waterproof Protean shorts are made from highly durable material, offering vital protection during a downpour or when riding in cold weather.

Incorporating waterproof zips and taped seams throughout, the Protean Shorts will help keep you dry either when on the trails or commuting. Unlike some waterproof items, these are not 'boil-in-the-bag shorts' thanks to the highly breathable material used, meaning you will be dry both inside and out. With twin waist adjusters, an elasticated waistband and mesh lining, these waterproof shorts also provide extreme comfort.

Key Features:

* Waterproof zipped pockets
* 10K waterproof / 5K breathability rating
* Waist adjusters for optimum fit
* Mesh lining
* Reflective detailing

The ratings given to waterproof/breathable outerwear indicate the degree to which they keep moisture from entering the fabric (the first number) and the degree to which they allow vapour and heat to pass through from the inside (the second number). The two ratings will always complement each other, if an item of clothing was completely breathable it wouldn’t be waterproof and vice versa. Therefore if the garment is both waterproof and breathable, great care is taken to find a harmonious balance between the two.

Waterproof Ratings

In order for a jacket, trouser or shorts to be considered waterproof in the outdoor industry, in particular the cycling industry, it must be rated at 5K or higher. Anything below 5K falls into the realms of being water-resistant and not waterproof. The waterproofness is measured by the amount of water pressure the fabric can withstand before the moisture begins to force its way through it. The waterproof rating of 5K (or remember it also means 5,000mm) really refers to a lab test. In order to come up with these ratings clothing manufacturers test their fabric based on how much water one square inch of fabric can hold without leaking in a 24 hour period. For example: if a fabric has a 5K waterproof rating, this means it held out 5,000 mm of water in one 24 hour period without leaking.

Breathability Ratings

The breathability of an item of clothing is the measurement of how much moisture vapour can escape from it. By being breathable it allows perspiration to be moved away from the body, transmitted through the material and allowed to escape. The breathability is measured by calculating how many thousands (k) of grams of vapour per square metre of material (g/m2) is allowed to be transmitted from the inside of the garment to the outside in a 24 hour period. So if an item of clothing is marked as having 5K breathability, the fabric would allow 5000g of vapour to be transmitted through the fabric across one square metre over 24 hours.
