Odor Resistant

Polygiene® odor control permanently protects your garments from smelling like a middle school locker room. Sweat itself is odorless, but it creates the conditions that bacteria need to multiply, and some of those bacteria produce odors. Polygiene permanent odor control stops the growth of odor-causing bacteria on fabrics, so you can wear more and wash less.

Active only on the fabric surface, Polygiene permanent odor control does not interfere with perspiration or with the skin’s natural bacterial flora. Polygiene particles are more than 100 times larger than nanoparticles and therefore are too large to penetrate to the skin’s barrier. Polygiene-treated fabrics have received Medical Class 1 approval in Europe, the same class that includes bandages.

Just what I was looking for
I've been wearing a crew-neck UA baselayer for a couple years when I ski that I really like, but find it's a bit thick and very fitted. I wanted to try a 1/4 zip for extra warmth and am so glad I gave this one a shot. It is lighter than I thought it would be, but still very warm (and so soft!). I also like that the fit is slightly relaxed (not baggy) which looks better when you are wearing it solo. I have a longer torso and it fits perfectly and does not ride up.

So comfortable
This is a great base layer. The stretchy,waffled material feels so nice on the skin,and it's much,much warmer than it seems it would be,considering its bulk... or lack thereof. I usually wear this right under my snap-t fleece jacket on chilly days,or with a wool thermal on top for extra cold days. I wash cold and hang dry,to keep the seams from bunching around the zipper (I do this with all my thermals). Really nice looking shirt too,you could wear this around town if that's your thing. I've worn it on almost all my recent forays to the river and am very happy with its wicking,insulation,and softness.

So cozy
I am always cold indoors and I love this top. It also performs well on hikes. I am petite (5'4") and it hits me at mid-hip,which is perfect. I weight 141 pounds,37-inch bust,32ish inch waist,and 38 or 39-inch hips,and a medium is perfect. The loft adds a great deal of cozy warmth without the need for bulk or itchy wool (I have very sensitive skin,and this does not trouble it at all).

Women's Fit Guide

Though each Patagonia® product is designed and shaped specifically for its intended use, we can generalize our fit descriptions in four ways:

Formfitting: Conforms to the body’s contours.

Slim Fit: Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.

Regular Fit: Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers.

Relaxed Fit: Drapes loosely on the body.
