A raincoat is, as the name suggests, a coat for the rain. And for it to be fit for purpose, it has to do just that. Protect you from the rain.
But if a raincoat does not have its seams sealed, it will leak and cause the wearer discomfort in the rain.
But what if the fabric is waterproof?
It doesn’t matter. The seams of a garment is one of their weak points. If a seam is stitch bonded then the need needle and thread process punctures the fabric with hundreds of little holes as the thread that holds the pattern together is woven through. These holes, though small offer the perfect opportunity for water to pass through. Weather Resistant Jackets are a perfect example of this. The fabric of the garment may be windproof and waterproof but the seams are not sealed which can cause water to enter and the wind the blow in.
Seam Sealing Tape is simply an adhesive tape that is used on seams of clothing and other manufacturered products to prevent humidity and water penetration whilst adding strength to the products seam joint.
To find out if your raincoat has been seam sealed, simply look to the inside of the garment and the seams. If there is a tape which has been bonded to the garment (using adhesives) then you have a seam sealed waterproof rain coat. If there is no evidence of seam sealing tape and you can clearly see the stitched seam, then you have a showerproof coat rather than an out and out raincoat.
How are seam sealing tapes applied?
Seams are taped with an adhesive single (1 layer), 2 layer or 3 layer seam sealing tape. Seam Sealing Tape is simply an adhesive tape that is used on seams of clothing and other manufactured products to prevent humidity and water penetration whilst adding strength to the products seam joint.

ARE ALL THE SEAMS OF A WATERPROOF JACKET SEAM SEALED?
Not always. Heavy duty jackets generally will be in what is called ‘Fully Taped Seams’. However on some garments, to make them lighter and more packable, they may only have seam sealing tape on some of the more important and critical seams in what is called ‘critical seams’. These will be found around the garments hood, neck and shoulder areas. These are the areas where rain most easily penetrates a jacket.
