The Arcteryx Phase AR Bottom are mid weight, full length base layers. Perfect for high pulse activities in cooler temperatures. The Phasic fabric keeps you warm when descending and dry when ascending. It has a soft touch and is stretchy to compliment its excellent fast wicking performance. The Phase AR Bottom utilizes hybrid mapping to reduce bulk, which in turn, leads to improved thermal regulation. They also have a Durable Anti Odour finish which means they will prevent odours for longer.
Phasic base layer fabric is compiled from two different yarns. The first is a non absorbent hydrophobic yarn, which will shed water molecules pushing them onto the PHi yarn. Silver ions are encapsulated into the hydrophobic fibres of the yarn, which provide anti-microbial properties to help eliminate odour.
The second yarn is PHi, a multi dimensional yarn, which wicks moisture laterally along the length of the yarn, effectively dispersing moisture evenly across the garment. Temperature regulation is improved as this dispersal, eliminates cold spots. As you slow down or stop, the fabric will dry quickly, as a result of the larger surface area the moisture is covering. This quick evaporation helps to retain body heat.
