Individual wool fibers consist of uncountable hollow spaces that are perfectly able to trap body heat. This effect is enforced by the curly construction of the fibre, called crimp, which gives lavalan a natural loft and forms millions of tiny air pockets creating a thermal barrier and delivering an outstanding insulation performance. Since wool is thermoregulating (moisture management) it also provides a cooling effect and prevents one from overheating during high intensity exercise or unexpected warm weather. So, lavalan always delivers comfortable, cozy warmth regardless of activity levels or altering temperatures.
Wool is a hygroscopic and hydrophobic fibre at the same time. Tiny pores in the epicuticle allow water vapour to pass through to the heart of the fibre. Wool can easily absorb and release moisture vapour up to 36% of its dry weight without feeling damp or clammy which is twice as much as cotton and thirty times as much as polyester. This makes lavalan highly breathable, quick drying and it keeps you warm even when wet or when sweating.
Wool always absorbs moisture from the atmosphere of greater humidity and releases it to the drier environment. Due to this individual adaptability wool is a “temperature regulator” that keeps you warm in the cold and provides a cooling effect when it’s warm and thus makes lavalan a versatile all-season fabric.
At the same time wool is naturally water-repellent. The waxy cuticle of the fibre doesn’t allow water molecules to pass protecting the body against the elements and ensures a constant and dry next to skin body climate and unmatched wearing comfort.
Perspiring is a natural way the human body regulates its temperature, especially in response to hot conditions or intensive exercise. High levels of perspiration lead to sweat which naturally does not inherit bad odour. What we know as unpleasant sweat odour only builds up over time as bacteria develop on our clothes. Wool’s capacity to absorb and to wick away water vapour prevents to build these bacteria. The fibre even has a self-cleaning and dirt neutralization property. So, you can use your lavalan padded garments longer without unnecessary wash cycles which makes it a perfect insulation for travels or multiday mountain adventures.
Care tip for your lavalan® padded garments
Often it is sufficient to hang out the garments in the fresh air and shake it just before the next use. It's been said that man-made textiles have spent years of research trying to recreate this process, which wool has done totally naturally all along.
Wool is a molecular coil-spring making the fibre remarkably strong, elastic and resilient. It can be bent more than 30,000 times before it breaks compared to 3.000 times for cotton. These properties make our lavalan very robust, durable and abrasion resistant. When wet, the fibre can be stretched up to 50% (when dry 30%) and bounce back to its original shape. The elasticity of the fiber creates a nice loft and a solid packability size for our lavalan waddings.
Wool is non-allergenic
Wool has no allergenic potential nor it is harming health in any other way. So even if lavalan has an animal background, there is no reason for allergy sufferers to step back from our insulation products. The wool fibre is antistatic and therefore has a reduced attraction to lint and fluff.
Proven by evolution and further developed by sophisticated breeding, wool has become mother nature’s miracle fibre which has numerous outstanding advantages over man-made fibres. Wool is a natural protein fibre that grows from the follicles of the sheep’s skin. It is like human hair in that it is composed of kreatin-type protein. Chemically these protein chains contain five elements: carbon, hydrogen, oxygen, nitrogen and sulfur. These five elements are combined into 19 amino acids linked together in ladder-like polypeptide chains.
