Arc'teryx Phase SL Bottom -

The Arc’teryx Men’s Phase SL Bottom is a lightweight base layer for any cold weather activity. For the guy that does it all, skiing one day, climbing the next, these long underwear bottoms are made to wick away moisture from your skin. The hydrophobic Phasic yarns disperses your sweat over a larger surface area, which in turn dries you out faster. I call that comfort technology! Arc’teryx has also encapsulated silver ion fibers, sounds fancy, but this will keep the pants smelling nicer (a little odor control never hurts).

FEATURES of the Arcteryx Men's Phase SL Bottom.
SPECIFICATIONS of the Arcteryx Men's Phase SL Bottom.


  • Phasic SL fabric provides exceptional moisture management
  • Phasic SL fabric is lightweight and has a smooth outer face that allows other layers to slide easily over its surface
  • Phasic SL fabric uses a construction called mechanical stretch that relies on the weave of the fabric to flex, rather than elastic threads, which creates a stronger fabric with more dynamic flexibility
  • Phasic SL - 70% polyester, 30% polypropylene
  • Phasic SL fabric incorporates polypropylene yarn with silver ion encapsulated into the fibers in order to provide odor control that lasts longer than chemical coatings
  • Flatlock construction improves next-to-skin comfort
  • Phasic SL fabric is hydrophobic in order to help transport moisture away from your skin


  • Next-to-skin fit keeps this bottom as close to your skin as possible in order to aid moisture transport and help you stay warm
  • Flatlocked seams and no side seams make for a comfortable fit, free of hot spots or irritating bulges
  • Gusseted crotch offers a supremely comfortable fit where it matters most, and the wide, laminated waistband has a soft finish on the side closest to your skin


  • Ankle length


  • Provides sun protection (UPF 25+)

Sure, there are plenty of synthetic baselayers out there, but only the Arc'teryx Men's Phase SL Bottom uses fabric that controls moisture, truly transports moisture away from your skin, and flexes like none other. Slide into this bottom in order to layer up for cold-weather trail running, alpine climbing missions, and day-long ski touring missions into the backcountry.

Keeps you warm while still extremely breathable. Fit is great, can't even hardly tell you have them on. Going in my flight bag.

They will make it into my standard bike-touring kit when travelling outside of high-summer.
