Buyers Guide To Waterproofs
Functional waterproof clothing is not fashion clothing; its price is dictated by the massive amount of science involved in keeping you dry in the pouring rain. It really is clothing as equipment and, as with all specialist equipment, you need to know how it works to get the best out of it.
Firstly, a waterproof garment will have taped seams and a coating or lining that will not allow water to penetrate under pressure. If you are planning on being active in driving rain, using a pack or sitting or kneeling on wet ground, then this is the garment for you. Anything else is water-resistant and will allow water to penetrate under certain conditions.
A jacket that is described as breathable is designed to allow sweat, or water vapour to pass through. Some fabrics are more effective at this than others. To work at their best they rely on a good layering system designed to transfer moisture from your skin to the jacket. Atmospheric conditions will also dictate how well they work; for example: textiles will work more efficiently when there is a large temperature difference between the inside and the outside of your clothing.
There are times when wearing a waterproof is the best choice, but on changeable days when rain is very light, a water-resistant garment may work better as generally speaking, they can transfer moisture more efficiently, they are more breathable. If it is a blustery day you may be better to choose a lightweight windproof garment for maximum comfort, popping your waterproof on only when the rain hits.
Don’t worry if you see your waterproof change to a darker colour and feel a little clammy inside – if you have brought it from us it’s not likely to be leaking! It’s just wetting-out. A simple tumble dry and/or re-proofing will restore your garment to its previous performance.
The best garment for you is the one that fits. It can have a gazillion pockets, the most articulated knee design or the very latest in technical features but if you are out on the hill and it is so big it flaps in the wind and drives you to distraction then it was not a good purchase. These days garments are tailored to fit. We are all different shapes and sizes and garment manufacturers go to a LOT of effort to allow for this. Try your garment on with layers, try the zips while wearing gloves, try it on with a pack but above all chat to us about what you should wear underneath.
