  • Wicks moisture away from your body very well.
  • Good warmth to weight ratio.
  • Fit is good.
  • Unlike wool baselayers, this one never feels “wet” when I stop moving.
  • Perfect for high intensity activities in cold temperatures since it wicks moisture away from your body so well.

Expert Reviews

  • The best synthetic baselayer on the market.
  • Incredible durability – if you beat the hell out of your gear, this is the top for you.
  • The most wind resistant base layer.
  • Great fit with nice stretch for movement.
  • Thinner material under arm pit helps dump heat.
  • Layers easily under other tops.
  • Possibly the most affordable (for what you get) Arc’teryx product on the market.


Reasons NOT to buy:

User Reviews

  • Not the most comfortable fabric.
  • Gets stinky easily.
  • Fabric is not the most comfortable but does feel nice, kinda like stretchy yoga pants material.

Expert Reviews

  • Not as breathable as merino wool.
  • Gets more stinky than merino wool.
  • Unlike wool, the fabric feels cold against your skin until your body warms it up.
  • Doesn’t dry as quickly as wool.


The Arc’teryx Phase AR Crew Long-Sleeve Top is lightweight, warm, and incredibly durable. While it attracts more odor and breathes less than comparable wool tops, its durability, minimal weight, and moisture wicking properties make this a top pick for synthetic baselayers.
