A pioneer of the soft shell concept the Rab® Vapour-rise system provides superior levels of comfort and protection. Vapour-rise balances wicking, warmth and wind resistance to maintain a comfortable micro-climate within the garment through a wide range of activity levels and weather conditions. It is best worn either next to skin, or more commonly over a wicking base layer.
- Extremely breathable, fast wicking and quick drying
- Highly wind and weather resistant
- High durability/abrasion resistance for its weight
- Comfortable, lightweight and packable
A micro-pile inner effectively wicks moisture away from the skin and a Pertex® Equilibrium® outer 'pulls' this moisture to the outside of the fabric where it quickly dries. The outer is also wind resistant and the DWR finish sheds rain and snow. This piece of kit should be an essential for every mountaineer, climber, mountain biker and off road adventurer.
Vapour-rise has many applications from single layer use in fast moving activities such as mountain biking through to forming part of a moisture management layering system in extreme polar or mountain environments.
So exactly what is Pertex® Equilibrium®?
Pertex® Equilibrium® is the result of extensive development work in the lab and field and balances high wind resistance with fast wicking and drying.
Pertex® Equilibrium applies capillary action technology conventionally used on base layer products. This means that during high aerobic activity, moisture is transported away from the skin to the outside of the fabric where it evaporates, hence creating body temperature 'Equilibrium'.
How does it Work?
Pertex® Equilibrium® wicks the moisture away from the body, the engine behind this process is your own body heat. On the outside the smaller filaments have a relatively high surface area which causes the excessive moisture to evaporate quickly. Through evaporative heat loss Equilibrium® reduces overheating, which in return reduces excessive sweating. This process creates body temperature 'Equilibrium'. The raised yarns on the inside of the Equilibrium fabrics create a micro-climate between the skin and fabric. This prevents the fabrics from sticking to the skin during intense activity. It also supports the moisture movement process.
