The essentials for the outdoors

Laine merinos Hopaal

Mountain excursions, city runs, business meetings. In this quest for balance between functionality and comfort, certain natural fibres are proving their worth. Merino wool is one of them, with a whole array of attributes that make it an invaluable everyday ally. 

Technical, high-performance garments are essential companions for pragmatic adventurers. Outdoor activities such as trail running have specific requirements: thermoregulation, breathability, odour resistance and durability. In this demanding context, merino wool is the natural, high-performance solution that doesn’t compromise on comfort or durability.

Effort and breathability

Merino wool helps to protect the body from variations in temperature and moisture variation during exercise. By reacting to changes in body temperature, it facilitates thermal regulation, which is essential during physical activity. Wool fibres are naturally breathable. They absorb large quantities of water vapour and help it to evaporate. The breathability specifically attributed to merino wool is due to its natural 'crimp': an undulating fibre characteristic that creates micro-pockets of air in the fabric, helping to isolate the skin from the outside environment and keep it dry.  

Regulate temperature after exercise

Wool clothing retains moisture longer than most other textiles, and so by releasing this moisture gradually into the air, it helps to maintain a higher body temperature and delay cooling. Merino wool has a hygroscopic capacity that allows it to absorb up to 35% of its weight without making you feel wet. It releases heat while keeping the wearer warm and dry in cold, damp conditions.

Great adaptability to all environments

In hot environments, merino wool fabrics have the ability to provide a cool sensation. Wool conducts heat away from the skin and insulates it from the outside atmosphere thanks to the micro-pockets of air enclosed in its texture. When it's hot and dry, it keeps you cool by transferring water vapour to the outside. Compared with polyester fabrics, wool can move up to 25% more moisture away from the skin. That's a drop in ambient temperature of up to four degrees Celsius.

Controlling perspirationn

Sweating is a natural way for the human body to regulate its temperature, particularly in response to heat or intense effort. During exercise, our bodies can release one to two litres of moisture per hour. High levels of perspiration are inevitably linked to the issue of body odour. Sweat itself has no odour, but when it stagnates on the skin, it creates a moist environment ideal for the bacterial proliferation responsible for these odours. The natural breathability of merino wool delays the onset of perspiration and then retains moisture to keep skin drier.

A sustainable choice with a controlled impact

The Merino wool used by HOPAAL comes from farms in New Zealand and Australia. Like European wool, it is washed in China before being transported to Europe for spinning and finishing. The kilometres covered by this fibre are currently unmanageable if we want to guarantee the quality and properties of Merino wool. In France, a few Merino sheep exist, but suitable textile projects have not yet been developed. According to our life cycle analysis of merino clothing, transport accounts for 3 to 5% of greenhouse gas emissions. The environmental impact of wool production is therefore more significant at the beginning of the chain, but this fibre has a long life. It requires less washing and is frequently recycled, extending its lifetime.

Mulesing-free merino wool

Top tier animal welfare is an unquestionable focus for a clothing brand. For its fleeces, jumpers and beanies, HOPAAL works with spinners who guarantee wool from farms that do not practise mulesing. The Merino overtshirt is made from recycled wool.
