A base layer that's ready to move.

The stop-and-go aerobic activity of ski touring, snowshoeing, mountaineering, and climbing can all lead to a bit of a chill if your base layer isn't up to the task. So Arc'teryx crafted the Men's Phasic SV Zip Neck Top for efficient insulation and wicking, so you can stay comfortably dry all day long. The top's soft, fuzzy interior warms you and draws perspiration away quickly, and its smooth outer face encourages quick evaporation. The Phase SV Top glides easily under your other layers, and a deep zip neckline lets you boost ventilation when you're breaking trail.

Great layer piece

  • Gender: Male
  • Familiarity: I've used it several times

This is a nice piece that is not to warm or not warm enough. Fit is what you get with Arc but I size up for a more comfy fit. If you want a piece that will last and works great this is the one. This is my second one cause the one my wife gave me for Christmas last year was so good.

Nice, just form fitting

Nice top. Breathable and flexible.

Great baselayer

I wear this as a middle layer and it works perfectly. Very comfortable, breathes well, doesn't retain odor, and it's not restricting at all. Pair this with the Phase SV bottoms and you've got a killer combo.

I'm 5'11 185 and the large is a pretty good fit, snug around the chest but a little loose around the waist.

not washer/dryer friendly

very snug fit and very comfortable, does a great job wicking moisture so that you don't freeze when you stop moving. the outside surface is smooth and does not grab at your other layers so everything stays put. The silicone tag melted/shriveled in the dryer and had to be cut out, I'm guessing it shouldn't have been washed with the "normal" clothes.

I own a bunch of Phase SL garments and while I don't own any Phase SV garments I will hazard a guess that the care instructions are the same: line dry (in fact, the Arc'teryx website says to hang dry this particular item). I have washed my SL tops/bottoms at least a dozen times, all with my other "regular" clothes. When the washing cycle is done I filter out the SL garments and hang dry them in my closet on regular hangers. This has worked like a charm. It sounds like you enjoy the performance of this top but just didn't consult the care instructions: why a 3-star review?

Beautiful and functional, but with limitations.

This shirt makes a deceivingly warm layer. Breathes extremely well. Too warm for activity in mild weather. Zipper is the standard and a very nice option to have for ventilating.

Fit is fairly tight. I got a size M, because I wanted it very tight, as a second from skin base layer, for hours spend standing in cold and windy conditions. I'm 6'2 175 lbs and just fits, but it's skin tight.

This garment is very comfortable, soft and light. No itch and very low odor retention.

Stitching inside, as seen in the images I supplied, is not fantastic. Quick and uneven, does not suit Arc'teryx style. Still very nicely covered zipper on the inside of neck for added comfort.

I would give this 4.5 stars if possible. The lack of attention to detail on stitching inside, cost as star.

Beautiful and functional, but with limitations.

Just fine

Nice garment, really comfortable...ran just a bit smaller than expected so we needed to go a size up. Super base layer for skiing. Highly recommend.

Killer Mid Layer

Let me start by saying that I am NOT a fan of synthetics. If I can I will always try to where merino socks and base/mid layers. That being said, I'm also a huge fan of arcteryx. I tried this on just in a retail store just to see how it fit and ended up liking it so much just as a casual pullover that I went straight home and ordered one from BC. I have been nothing but impressed with how well this has acted as an insulating piece. I've worn this out snowshoeing, boarding and even cleaning up in the yard and every time it has been just as good as any wool item that I own. I've liked it so much that after a month of solid use I went right back to BC and bought a second one.

How warm is the Phase SV fabric compared with the Power Stretch fabric as used on the Rho AR?

Responded on

I think it's just a little less warm, but not by much. The Phase SV shirt I have is really warm for how thick it isn't. It does do a way better job of controlling moisture, in fact, it never feels swampy even when I'm getting sweaty from the insulation value.

Responded on

In my experience Brandon is right.

Good base layer

This is the best baselayer I've owned, which is why I own two. I love it and I look forward to getting the bottoms, soft, comfy, WARM, and not itchy at all. I went with a small for the next to skin feel, try a size smaller if possible, you may like it. On a side note, the Graphite color only has an orange zipper TAB not the entire zipper track, would've liked it to be as pictured because it looks nice, but oh well, this does not change the quality of the shirt. Yes, I would recommend this.

Would buy again!

I'm 6'4" and 180lb, i wear the large and it fits like a dream. The athletic cut fits me perfect, long enough to cover my belt loops and even my long monkey arms. The fabric is stretchy so you can move freely as is it wasnt there.

I wore this as a pull over every single day this winter.

Great Performance Top

Very high quality and excellent fit. Am 6' and 195, use XL for trail running and XXL for casual. Great companion to Rho AR fleece, when temps don't require heavier top. Would buy again,

fantastic insulator

love arc'teryx and love the phase sv. great for using while layering up for a cold day. also great as a standalone piece on those warmer days for running. sweat evaporates super quick, and doesn't hold onto that smell that most of us create during those longer runs! would recommend it to anybody.

GREAT base layer

I usually wear medium, but since this is a baselayer I opted for the Small and it fit's perfectly, you may want to try a size down for a more snug, next-to-skin fit. Very warm and comfortable for such a thin layer, perfect and worth the money. I would rather have one of these than have 3 of any other brand, but I liked it so much I bought a second. I can't wait to get the bottoms. Please note that the Graphite does not have an orange zip, only the zip tab is orange, the zipper track is graphite.

very nice but thin

was expecting thickness to be similair to the old patagonia expedition weight stretch fleece, but this is thinner. very warm however just thin, good for layering.

I like a well fitted baselayer (small Patagonia capilene) for my 6'00" height. It's important that it's long enough for my height but also that I can throw 2 layers over it in a pinch. Everyone says that Arc'teryx is an athletic fit and that you should order a size up... would an M from the skelebird compare to an S from Paty?

Responded on

I'm 5'11 170 and the medium in the Phase SV fits me well-not too tight but is close throughout. Sleeve length is right as well. I guess a Sm would be fairly tight on you. These do have more stretch than a capilene.

What exactly is this material, and how does it stack up against good old merino?

Best Answer Responded on

The Phasic is a blend of polyester and polypropylene, both of which have silver ions embedded in the thread to help with odor. This fabric wicks and dries waaay faster than merino, but isn't as odor resistant or insulative when wet. It also seems to be more durable than merino,in my limited experience with the Phase AR.
