Merino Skins Base Layer

Heat sensitive photos illustrate the power of Merino Skins to keep your body cool when the going gets hot. The much greater red/yellow area on the back of the 100% Synthetic wearer (man-made fibres such as Polypropylene/Nylon/Polyester) shows that Merino Skins are at least 2°C cooler – a real performance edge.

Body Temperature Regulation

The key to greater performance is keeping the body’s temperature at its optimum comfort level. Merino Skins constantly monitor the body’s temperature and moisture levels and naturally adjust body temperature to maintain the optimum level of comfort.

The Merino Skins Edge

Merino Skins provide the power to keep you going. To keep the body’s muscles working at full capacity during activity, the body’s temperature must not rise excessively. Merino Skins are highly efficient in body cooling during strenuous activity. At the same time, they protect the body from the outer cold environment- keeping you miles ahead – the natural performance enhancer.

Merino Skins will “wick” moisture away from the body (up to 27% more moisture than any comparable synthetic)

Merino Skins Merino Wool Performance Underwear vs Synthetics

Unlike petrochemically based synthetic thermal underwear – natural Merino Skins key feature is its ability to regulate the body’s optimum comfort level – never too hot, never too cold.

How? The key is moisture and temperature control. Conventional synthetic underwear is manufactured from chemical-based fibres or plastics which have very limited ability to breathe or to absorb moisture. While they can “wick” or move moisture away from the body, they merely transfer that moisture to the outside of the garment creating a wet, sweaty, unhealthy environment which becomes unbearably cold in the winter months and uncomfortably hot in the summer months.

This is where Merino Skins is different – Merino Skins will “wick” moisture away from the body (up to 27% more moisture than any comparable synthetic) and because of Merino Skins natural breathability, it will evaporate that moisture quickly, leaving your body drier and more comfortable in all types of conditions. Cool in summer, warm in winter and 100% natural and organic.

Thermoregulation and Moisture Control of the Body

The key to greater performance is keeping the body’s temperature at its optimum comfort level. Merino Skins constantly monitor the body’s temperature and moisture levels and naturally adjust body temperature to maintain the optimum comfort level. In cold or damp environments, Merino Skins instantly generate heat through a unique molecular process known as heat absorption. In hot or warm environments, Merino Skins release moisture as a vapour, cooling down the body. Truly nature’s miracle thermostat.

Superior wicking abilities

Merino Skins rapidly absorb sweat and pump it through the outer layer where it quickly spreads and evaporates. This powerful wicking transport system keeps you dry throughout the strenuous exercise – up to 27% more than synthetics.

The Structure of Merino Wool Fibre

Each minute fibre is made from interlocking proteins called keratins – the same proteins that act as a protective outer layer on your own skin. This gives Merino wool the unique ability to work like a second skin – in total harmony with your own body’s protection mechanisms.

Wool not only stretches and moves when you do – it insulates your body, keeping you dry when you sweat, cool when you are hot and warm when it’s cold

The structure off wool fibre

A microscopic look at the surface of an individual merino wool fiber reveals a protective scale structure. The scaly outer layer repels water, while the core remains highly absorbent. Under normal conditions, the hydrophobic scales shut moisture out. However, as humidity increases due to body heat and perspiration, the scales open slightly to allow the sweat-absorbing core to be exposed. These scales hold the fabric away from your body maintaining a dry comfortable feel.

Odour Free

Merino Skins do not retain offensive odours, unlike all synthetics. They evaporate perspiration and thereby eliminate the breeding ground for odour causing bacteria. That’s one more important benefit for you to enjoy: wearing Merino Skins will inhibit bacterial growth and offensive odours.

Static Free

Merino Skins fabric is in harmony with the body’s natural electrical field, thus unlike synthetics which carry static electricity that runs against the body’s blood structures, Merino Skins will keep you comfortable in natural harmony.

Flame Resistant

Natural Merino Wool is an excellent flame resisting fibre – unlike synthetics which will incinerate, combust and melt on impact with any naked flame. Sitting around the campfire, you can feel protected, safe and rest assured that your natural Merino Skins thermal undergarments will protect you against any stray sparks.

Dries Quickly

Drying time in our busy lives is extremely important – with the latest in technology, the care of Merino Skins thermal wear requires no special handling as they are fully machine washable.

High Level of Inbuilt UV Protection

Merino wool has a much greater level of natural protection against the sun’s harmful UV rays. Wearing Merino Skins outdoors significantly increases the level of protection against UV rays as compared with other thermal wear.

Double Knit – Interlock Fabric

Almost all merino wool base layer garments on the market are made from a fabric known as single knit or jersey fabric. These fabrics are knitted possessing only one single layer – this knitting style can be compared to ladies stockings, where if a small hole or run appears in the fabric, the fabric pulls away like a drawstring and is ruined for life.

Single knit jersey fabric is primarily used to save cost as there is less wool in the fabric, this however also results in compromising fabric performance with reduced garment life despite the actual wool fiber being of high quality.

This is why so many experience competitors garments giving up only after a few washes.

Merino Skins however are made from a superior fabric known as double knit or interlock fabric -where two layers of fabric are interlocked together – resembling a 2 ply construction, resulting in a fabric that is super soft, durable and long-lasting.

Our fabric is run-resistant, firmer and much more stable than all the merino products on the market today. This is why our garments can be machine washed (no handwashing necessary) and can be tumble dried warm and will last and last.

Our double knit interlock fabric provides a much higher level of insulation than competitors single-knit garments due to our twin set of yarns knitted together resulting air pockets formed between the two sets of yarns, trapping warm air between the fibers providing a superior level of insulation – ensuring Merino Skins will keep you warm when you need it most.

Thousands of Merino Skins users around the world have already experienced the double knit interlock fabric difference.
