Waterproofing Terms Explained
Start with the product category and test
“Waterproof” can refer to different evidence for clothing, tents, footwear, bags and electronics. A number is useful only when you know the test, unit, sample and finished-product scope behind it.
Common clothing and shelter terms
- Water-resistant: limited resistance, not a universal storm or immersion promise.
- Hydrostatic head: a fabric water-pressure result; seams, zips, wear and construction still matter.
- Seam sealed or taped: describes how specified seams are protected; check whether every relevant seam is included.
- Breathability: moisture-vapour performance measured by a stated method. Results from unlike methods should not be ranked directly.
- DWR: a surface treatment that helps water bead and can need cleaning or renewal. It is not the waterproof membrane itself.
Footwear and bags
A waterproof lining does not stop water entering over a boot collar. A coated bag fabric does not automatically make the seams and closure immersion-proof. Check the complete construction and stated use.
Electronics ingress ratings
Ingress ratings use defined dust and water test conditions. Do not convert a rating into broader saltwater, impact, hot-water or long-duration claims unless the maker explicitly supports them.
Care is part of performance
Follow the product’s wash, dry, cleaning and reproofing instructions. The connected catalogue includes distinct treatments for clothing, softshells, leather and canvas; they are not interchangeable.
Browse current care and repair products, then confirm material compatibility on the exact label.
Comparison rule
Compare like test methods and complete products. When the evidence is missing or unlike, describe the uncertainty instead of inventing a winner.
