Published Jan 11, 2026
Wool is a natural fibre and it likes to breathe: it is able to absorb up to 30% of its own weight in water vapour, so if kept in direct sunlight it can "sweat" releasing that moisture as water vapour, causing condensation to form water droplets on the inside of the plastic bag which in turn can cause damp patches when ...
Can water pass through wool?
Does wool repel water? Wool fibers in the fabric are 97% protein and 3% water-resistant lanolin. This is enough to naturally repel water with extra DRW coating applied to the outer layer. Even fine wools have the natural ability to repel water.
Is wool good for wet weather?
Wool is also able to soak up as much as 30 percent of its own weight in moisture without feeling wet, which is one of the reasons it can still keep you warm even in the rain [source: American Sheep Industry Association].

These air pockets are instrumental in keeping warmth from escaping through the material.

What fabric absorbs moisture?
Moisture Absorbing Fabrics
The most common absorbent fibre used is cotton, but other fabrics have recently been designed that are more absorbent, such as modal, micro-modal, Tencel®, and other viscose-based fibres. All of these are made from the same base material – plant cellulose – which loves water.
