Awesome color, fit and it is warm! Perfect with leggings and after a hike or just running around! Want more in awesome colors! Bought avocado color and returned due to color

Awesome, but hated this color
Review by Jc

Bought this in red and loved it so thought I'd buy in. Avocado. Color is dingy green. Maybe better with black zipper to go with black leggings but not a fan of color
Fit is awesome and it is warm. Avoca

Lovely Grey power dry
Review by Joosje

Loved the grey with the yellow zip. Unfortunately, I had to return the small that was too tight and the medium, in that color, was no longer available. I hope you will have the same power zip in stock again.

Great base or mid layer
Review by Sage

I love the Women's Basis Power Dry Zip Neck. The color is gorgeous and it feels really nice against your skin. Some base layers are itchy to me but I can wear this without anything underneath. I have also worn it over a t-shirt on cool mornings when I am hiking. Would definitely recommend it!

Perfect city piece
Review by nk

Living in Chicago, I knew I needed a baselayer for the cold winters we have so I went with the power dry zip. I love how it's not so form fitting and has a little give in it to layer underneath and not be super bulky. I went with the gray color because I liked the pop of color in the zipper. I also like how the zipper is a bit longer than your average half zip pullover because it gives it a more unique and different look. So far, I have been wearing it when i'm running errands around the city and it has been super breathable and unlike other half zips I own, I don't have the problem of overheating easily, which is a huge plus!

Best Mid Layer Ever
Review by Trail Boss

The Women's Basis Power Dry Zip Neck is the best mid base layer ever. It performed in rain, sleet and snow during my Patagonian adventure. This is the perfect weight to maintain warmth without overheating. Quick drying and wicked sweat during intense hiking. Stylish with great color choices. I will be placing an order for another one very soon!

Outstanding product and fit
Review by outdoor enthusiast

Great top - Loved it from the minute it arrived at my doorstep. Fits great, is stylish and keeps me warm while skiing.

Great pullover for fall camping
Review by ALMJCC

I love this pullover for casual wear as well as camping. I wore it every day on a 5-day trip because it was so light weight, resisted odor and never wrinkled. I also like that it is fitted and f\flattering. I purchased several as gifts and everyone loves it. It runs true to size and the thumbholes are a nice plus.

The teal zipper is a nice touch
Review by TLC

The sleeves were too tight for my rather muscular arms.

Review by riderunskateski

My most favorite wool-ish base layer. It is wicked warm during cold days, but equally well efficient at keeping me cool when I wear it alone. It is uber flattering, as it is has more "structure" that some of my other wool layers - less clingy. It is truly a favorite, and gets worn constantly.

Excellent base layer
Review by Jillo

I've been wearing the same base layer for skiing for probably 10 years, mostly because I just haven't seen anything better. Out of boredom and the desire to branch out from the usual brands, I decided to give Stio a try. So glad I did! The Power Dry Zip Neck is warm but not too warm, longer than most base layers, and stays down rather than riding up like many tight-fitting tops. It is form-fitting without being tight or skimpy-looking. I am 5'5", 120 lbs and the small fit perfectly. Now at least my base layer is up to date!

Loving the wool.
Review by SkiMT

I usually have a difficult time wearing wool products (itching, sneezing, etc.), but I do not have any issues with this base layer. I have worn this probably 10 times this season and it is warm, but I am finding it works best for me on warmer days when I need more sweat wicking properties. I use my Ole Glory Half Zip for the really cold days.

Functional and Versatile
Review by NiPH

I have had this for almost a year, washed it numerous times, worn it for a variety of activities and it still looks great!

Great top for cool weather.
Review by Heather

This top was a bit different from what I expected on-line, but it fits great. The wool is great for a cool day. Great color and fits my body top well. I'm 5'7" and 140 and the medium fits perfectly.

Great base layer.
Review by Laurel

This top is warm, lightweight, soft against the skin, and easy to move in. I wear it as a base during cold weather runs and cross country skiing. It wicks moisture well and keeps me warm after my run or ski, when I can't change clothes immediately after finishing. I need a few more of these!

Good cut, great quality
Review by BRigor

Love this layering piece. I'm 5'6" and petite - small works great on it's own or over a thin base layer. The cut and fit are very nice and as usual, Stio quality is exceptional!

Love it!
Review by NiPH

Flattering fit and ever so functional. It is great for layering. Nice and warm but thin, so I can wear an undershirt and add a sweater without ever feeling bulky or constricted. I'm sensitive to wool and have no problem. It washes great too!

non- itchy-scratchy
Review by Snowzoom

I finally have found a wool blend base layer that does not make my skin crawl. And it is long enough to cover my booty when I am skiing. I want one in all the colors now!!

Exceeded My Expectations!
Review by Ty

I must say I am impressed with my first order from Stio. I just received the package in the mail with this jacket and also the basic Henley. One for me and one for a Christmas gift for family in Vermont.
From the fast shipping to the classy presentation, but most importantly the beauty and quality of the clothing I am truly impressed. This zip neck is definitely above average in quality, style, and function. I purchased the navy blue and I just love the yellow zipper accent.
These items are price and I have been eyeing them for a while and snagged them when they had a sale after Thanksgiving. But I think the quality makes them worth it.

Best base layer - a must have!
Review by Pumpkin

This is the best base layer - comfortable, great fabric and fit, and so warm with a great collar. First purchased the gray and will add more colors for this winter! Wore it this past weekend for rugby and football games - so perfect!

Love this item
Review by Suze

I bought the gray - I'm a traditional medium and the medium is perfect. This item is warm, flattering and functional. I have smartwool half-zips but prefer the Women's Basis Zip Neck and wore it ALL the time. Thank you Stio!

Warm yet lightweight
Review by Maddy (Staff)

I decided to get this particular item in a M (5'6" 130 lbs). I have layered both a basic tank and a thicker tee underneath it and been extremely warm and comfortable. Unlike many other half zip pullovers, the Basis Zip Neck is very lightweight and does not feel constricting. I definitely recommend this for warmth, comfort, and style!

order a size up
Review by Emilie

I'm 5'8" 135 lbs and I got a size small, which is the size I normally wear. I love the way it fits, but the thumb holes are short on me and end up hurting my hands. After reading the other review here I think maybe a medium would have been better. Besides that, I love the fabric, and it has a flattering fit. I've also received compliments on this and feel like I can wear it anywhere.

Can wear it anywhere
Review by Jo (Staff)

I'm 5'4", 125 lbs. and I wear this layer in a size medium. The small was comfortable. However, ordering a size up allowed more room to layer underneath and still not be too tight. I was worried if it was too fitted it might ride up during activities.

I can wear this layer to work, skiing, a dinner party, etc. and look good/ receive compliments all the time.
