EASY CARE

Follow these tips for the best performance and longest life for your garment:

Machine wash cold inside out and Tumble dry low.

Avoid fabric softener. Though it won't damage the clothing it does coat the fibers in a wax that neutralizes many benefits of Merino.

This midweight top offers exceptional insulation without bulk, making it ideal for layering or wearing solo. Whether you're exploring the outdoors or heading into town, the sleek design and stand-up collar add a polished touch to this performance piece.

Crafted with ultra-smooth merino wool fibers, it’s as soft as it is functional. The breathable, moisture-wicking fabric keeps you dry during intense activities, while quick-drying and odor-resistant properties ensure long-lasting freshness. The adjustable 1/4 zip lets you customize your look and comfort, and the foldable cuffs provide a personalized fit. Stylish, warm, and incredibly comfortable—this top is your new cold-weather essential.

Kelly P.

Husband loves it, lightweight but warm and perfect fit!

Angela B.

My husband loves the woolx 1/4 zip! He is waiting patiently for the new restock on sizing as a medium was too small.

Kirstie M.

Very comfortable and smooth texture. Lightweight but still warm

John S.

Great Feel and looks great too. This was a great layer to have during these very cold days that we had. I wish I would have gotten it sooner. It would be a 5 if made in America.

Margery T.

Wish I’d know about Woolx sooner! Look forward to my next purchase!

Melissa L.

Fits and looks great! Cozy and warm

Joyce T.

This was a gift for my brother in Wisconsin and he is really happy with it. I knew he would be because I’ve purchased Woolx tops for my husband and he wears them every day.

Eileen C.

It was great

Jennifer G.

This is a great piece, looks really sharp on my husband, and feels great - both on him and to me when I hug him in it!

Flora W.

My son-in-law loves it !! Wears it on runs up Aspen mountain everyday ! You should use Bryan as an influencer ! 418 thousand vertical feet last year Bryan did up Aspen mountain !

S J.

Good quality merino. I was expecting the heaviest weight quarter zip to replace the one I've ravaged over a few years at work. Its still holding up overall except for some fraying at the cuffs, which is to be expected the way I abuse my under layers. I'll use the newer lighter weight quarter zip when I need to be more presentable!

Sarah G.

Christmas gift for my husband. He likes it! It’s stylish and warm. Easy to layer and dress up or down. It is a slim fit. Hope it wears and washes well.

John M.

Fits and looks/feels great

Marge G.

My husband loves his wool shirt he received for Christmas and wore it already.

Elizabeth M.

He loved it. Great quality and fit!

Caroline C.

Husband Loves the merino wool zip up ! very comfortable

Joel B.

Soft high-quality product. My only complaint is that it’s sized more like underwear than a shirt.

Elle S.

Beautiful, soft. Perfect for layering!

Kimberly M.

Warmth is wonderful

Hannah K.

Got this for my husband as a gift. He loves it! The smooth fabric, the quarter zip that keeps his neck warm and the medium fits him perfectly (5'8", 175 lbs). It's a nice base layer under henleys or button downs or hoodies.

Bill K.

Great garment. Use it all the time.

MARK F.

Fits and feels great.

Kate B.

Fabric so soft and elegant. The fit size L for our son was perfect.

Ted S.

Great quality, perfect fit, and easy to pack!

Rafael G.

A size small fits me very well: not too slim or too baggy (I'm 5'7", 38" chest, 30" waist). The finish and stitching is clean with no loose threads. And despite it being kinda lightweight, it kept me comfortably warm on a 3-hour flight just by having it on top of a simple tee shirt.

Genae E.

Love this 1/4 zip. Soft, medium weight, and fits well.

Amy C.

Fit is great! Ready for Iceland!

Stephen K.

It is a versatile weight that goes with anything.

Tracy H.

I buy one every year for my son in law.

Susan T.

My husband liked it so much he bought a short sleeved shirt from woolx. That’s saying a lot!

Cherie E.

Thin,,lightweight and adds warmth. Excellent travel piece.

Shari S.

Bought this for my husband for a cruise during the winter. I've been wearing Woolx pieces for years and finally got him a great looking sweater. It looks and feels so good on! One of my most favorite things about Woolx is that black is tru black and always looks put together and sharp! So happy !

Donald R.

Fantastic look & feel - lightweight and comfortable. I plan to purchase a few more very soon. Would recommend

Kristin W.

WE love the product

Dan

Favorite shirt! Wish it came in more colors I’ve had two of these shirts for several years and they are perfect. Below freezing base layer, or alone for cooler days. Zipper is perfect for temperature regulation. Mine is a bit tattered from heavy use but still doesn’t stink. They used to make these in some amazing colors and wish they still offered that as I’d get one of each.

Elisabeth Zimmerman

Great product Comfortable,easy to wear and straightforward purchase

Aaron Morris

Weird fit Sleeves are short compared to length of body. It's a weird fit. Maybe designed for fat people? If you have a big belly belly it might not be so long in the body. Clearly not designed for people who need an athletic fit.

Carol MartensPrice

Perfect. He loves it. More colors in this style please.

Marsha Reeves

Looks Great on My Man Perfect fit, excellent design, merino warm, washes nicely....what more could someone want?

Jim Kaufmann

Explorer 1/4 Zip Love this shirt; it’s stylish, comfortable and versatile. You can wear it casually or dress it up under a sports coat. Very satisfied with the purchase.

Mike

This in large size is a perfect fit for me, I am 5’ 8” lbs slightly pudgy upper body and belly, the cut was perfect for me and the sleeve length not too long and like some other styles of the same size from other manufacturers which tend to fit the longer skinnier arm type of body. Very comfortable feel and nice look whether you zipper up with the neck or fold it back to make a cooler

Bill
