    Versatile base layer

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I used to be a firm believer in the merino wool baselayer as it wicks well and almost never gets stinky, but the phase has made me change my mind. though it doesn't have the anti microbial properties of merino, it performs much better! I normally always have issues with my baselayers not wicking enough, leaving me cold and damp, but this baby wicks away everything leaving me warm, and ultimately happy. unless there is a wicked windchill, I only wear this, my atom lt vest, and a shell... plenty to fight the elements and tear up the mountain. overall, I would highly recommend this piece and it is a must have for every outdoor enthusiast.

    Best Base Layer Out.

    • Fit: True to size
    • Size Bought: Medium

    Once again Arcteryx strikes gold. I have owned a number of base layers over the years but none have come close to matching the quality as the phase. Its super comfortable to wear as a next to the skin base layer. Its not to tight breath really well and most of keeps you nice and toasty.
    Warm and breathable.

    Awesome Shirt...stink stays around

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Great shirt, I am ex military and a hunter and have used a lot of base layer products. This is the best construction quality of them all and works great.

    I love it!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: M

    I love it much it and waiting for the big deal for a long time.Fortunately I've been waiting for it! It is very comfortable to wear.I am 5'90,160 and the size of M is very suit for me.At first I struggle to buy which between phase sv or phase ar,also the pho ar is the best one I want ,but I can not bear the high price .So finally comparison of the two goods carefully , I choose phase ar. When I received the goods I'm very glad I didn't choose the wrong one! It is very light.It can easily cope with the temperature of 30F to 40F when I wear it running in the autumn and winter. It is only a single wear.The next target is phase bottom, I am still waiting for the good deal!

    Perfect Base Layer

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Everyone hypes merino wool but this piece is now my go to base layer. It fits perfect. I am 5'11, 190 and a Large fits just right. It has a very athletic/next to skin cut. There shouldn't be any bagginess when wearing it. About the product: there is a SV Zip-Neck version and this AR Zip-Neck version. They are essentially the same product with a difference in warmth/thickness/stiffness. I wear the AR for days 65F-20F as my base layer and the SV for days 20F-0 or below as my base. It has been a year of heavy use and it still looks and feel great. Machine washable. Buying more of this product.

    Was lucky enough to pick one up on steep and cheap. It fits well, is light but surprisingly warm, dried quick. Great for a variety of activities...running, hiking, skiing....anything u would need a base layer for. Highly recommended

    Comfortable and light

      This is my new favorite baselayer when it comes to snowboarding, hiking, etc. Very soft and comfortable to the touch and does a great job of regulating temperature and wicking moisture. The odor resistant claim is valid and the flexibility in the top is great. Fits true to size, I am 6'0 173lb and a large is perfect.

      Awesome feel

      • Familiarity: I've used it several times

      Whether you are going on a hike trying to keep it simple, or looking for a great layering piece to go skiing and have under your down jacket and shell jacket this is the way to go. Great feel: Soft, good stretch and a nice conforming feel around your chest. I am 6'1" 170-180 and a large fits really well!
