Nikwax Analogy Waterproof fabric is more than just breathable, it is directional.
Nikwax Analogy Waterproof FabricThis means it is capable of moving liquid water away from your body and not just water vapour.
It is essential to avoid a build-up of water in your clothing system when you are working hard, as too much retained moisture will lead to your body rapidly chilling when you stop and rest.
In conventional clothing systems, approximately 20% of sweat production is dealt with effectively, leaving the remaining 80% trapped inside.
Nikwax Analogy garments are unique, in that they pump out this 80% of liquid water and allow it to drain away; you are left feeling dry and comfortable.
