A top-performing baselayer for the colder days of working up and charging down the mountain.

Keeping pace on the skin track takes more than just a healthy heart. The Arc'teryx Phase SV Comp Top uses strategically placed Phasic SV and Phasic AR panels to both insulate your cold zones and allow you to breathe for efficient uphill travel with or without your jacket.

  • Phase AR fabric on the back and underarms provides enhanced breathability and moisture wicking to regulate comfort during stop-and-go winter touring
  • Once you transition into downhill mode, the heavyweight Phasic SV fabric on the front, neck, shoulders, and top of the sleeves holds your body heat close while you scout your line from the windy ridge
  • With a next-to-skin fit, this baselayer top dries quickly, breathes, wicks your sweat, and minimizes odor for exceptional cold weather performance
  • Flatlock seams let you move freely without chafing your dry skin
  • The zip neck provides a bit of venting and easy on-off, while the zipper locks into place
  • Roll-over cuffs cover hands during glove-free breaks on the trail
  • A drop-tail hem provides security against drafts when you charge up switchbacks

Is ok not special

Fit is big
Colour is unusual, looks much better in photo than real life.
Is expensive for the look, functionality. I suggest buying other brands rather than this. I reckon $40 is where this should sit.
Nothing wrong with the item, just not ecstatic that I Now own it

Get one!

5'10 1/2" 167 7%bf
a Large fit snug/perfect
Skiing - wore it last season in Utah as a base layer. From warm temps at the base to cold and windy at the peaks/ridges, the shirt worked perfectly.
Climbing in West Virginia - on cold days, as a base layer, helped maintain temp and moved with me VERY well.
Road biking in PA - base layer with biking jersey over top - cold morning starts through 20 degree temp swings the shirt was amazing - never too cold or too hot.
MD Surf trips - coming out of 40+ degree water with an onshore breeze blowing, this was the first thing I put on after stripping off the wetsuit.
I love Patagonia stuff but this line is better - the first thing I throw in for a trip when I know I'm gonna be out in it all day and NEED to stay warm!

Phase SV Comp

  • Gender: Male
  • Familiarity: I've put it through the wringer

I own this shirt in graphite color and wanted to point, that the back is actually yellow (just like sleeves).
I mostly use it as a base layer for running when it's cold outside and works just fine. Nothing really special and probably a bit expensive for it's value.

Does anyone know what this product feels...

Does anyone know what this product feels like on the inside? Is it fleecy or is it smooth?

Responded on

It's got a really soft fuzzy texture. I would recommend to not put this in the dryer as the light fuzz is pretty heat sensitive.

Responded on

Overall, I find this to be a tremendous shirt and I'm taking advantage of the sale to get another one. However, my reaction when I first put it on is that the shirt feels almost harsh. I have a moment of disappointment and I can't believe that I'm reacting badly to an Arc shirt. But then it passes and the shirt feels just fine. And it really seems to work. I'm very skeptical of wicking claims, especially for running where you produce a lot of sweat, but I now own all four types of Phase shirts because I think they do a good job of wicking, along with the fact that they fit great and look great, too.

Phase SV Comp

First thing to know, these run a bit big...which I find unusual for Arc. I'm 69"/205lbs/44" chest with a muscular build. I order the XL because I didn't want a compression shirt and because I wanted to layer underneath. Cut to the fit too loose for what I imagined. This shirt is made for next to skin so the XL was only fitted around my biceps, every where else, loose. So I sent it back for an L. Very comfy and from just trying it on for size I can tell that it's pretty warm too. Sleeves are really long w/ typical Arc ergos, it's also nice and long for tucking or "no rise" slack when lifting arms. Shirt looks really awesome in person and not too overly technical if you wanted to wear around town, at least not for me. Color was true to the pics. Lata peeps.
