The Arcteryx Phase SL Briefs are light and comfortable underwear that are ideally suited for intense activities.
Constructed from the SL, which is the lightest of the Phasic™ fabrics. This ensures absolute optimal wicking properties and is ideal for high aerobic stop-start activities. Manufactured using flatlock seams and a soft waistband, so you are ensured comfort with no chafing.
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.
