Why insulation made of genuine sheep Wool?We never stop the process of testing new insulation materials, both natural and synthetic, in laboratories as well as in the nature. Getting new experience we are able to introduce top quality products.
Why has Wool beaten synthetics? How does Wool work?Air is the key. The main task of all insulation materials is to keep a layer of warm air around your body. Thus hollow fibres, curly fibres and many others have been developed. Not the fibre but the air it contains and keeps matters. The more air, the more body heat it retains. Wool fibre absorbs vapour and gives out vapour – the magic no synthetic material can perform (it is able to absorb 30 % of moisture compared to its weight).
Wool insulation actively supports thermoregulation of your body. Thanks to the fibre structure it is able to keep the balance between the heat emanated by the body and the heat transmitted to the surrounding. Down or Wool?These insulation materials are close to each other and get more popular because of:

Top quality goose Down used by Sir Joseph® keeps you warm even in the most extreme conditions.
|
Wool has longer tradition warming up a human body than Down (or Feather) and thanks to its unique properties and the current trend of healthy lifestyle it is back to keep you warm during active aerobic activities.
|
* Sir Joseph® uses Down with hypoallergenic treatment minimizing the presence of dust mites.
** Expedition jacket Sir Joseph® 8000 II for extreme mountains or polar adventures up to -40 °C filled with Down weights 1120 g. A jacket filled with wool with the same thermal comfort would weight 2500 g.
Activities and conditions suitable for Wool and /or Down?
Choosing our sports outfit we take into account conditions prepared by the nature (temperature, weather) and given by our decision (place and intended activity):
Low temperatures up to severe freezing (-10 to -40 °C) and less aerobic load mean: Down wins without any doubt.
The body emanates heat but not enough to make us feel comfortable. Quality insulation with minimum thermal loses is needed. The lighter, the better. Days like these are ideal for a Down jacket.
Temperature rises (-10 to +5°C), a man moves faster, the body emanates more heat and generates body moisture (sweats).
The need to insulate remains to keep the comfort, plus the question of body moisture has to be solved. Either you can use Down garments with less fill weight (thinner Down jacket), or a Sir Joseph® ALPIN WOOL jacket. Possibly combine the two, ALPIN WOOL jacket and Down vest. ALPIN WOOL for constant comfort during the whole activity. DOWN for immediate and instant warming up while having a rest during climbing or summiting the peak.
Temperature rises above 0°C; Wool beats Down at most activities.
Aerobic load does not require so much insulation. The only issue matters - the moisture. The thermal insulation is to be solved after the performance, while taking a rest and relaxing. Warmer conditions are in favour of Wool.
