Women's PerformaWool Aero Weight Tee

I picked up Cozy Zero's PerformaWool Aero Weight Tee in Light Blue, and it's easily one of my favorite hiking shirts I've owned. The color is gorgeous in person, and the fabric is incredibly soft and lightweight. It feels cool when the trail heats up but still provides just enough warmth during early morning starts.

I recently wore it on a long hike, and it exceeded my expectations. It breathed exceptionally well on the climbs, dried quickly, and never felt heavy or clingy. The merino blend did an amazing job keeping odors at bay, so I still felt fresh after hours on the trail.

If you're looking for high-performance hiking gear that also looks great for grabbing lunch after the hike, this is it! I've already ordered this in more colors! I have a feeling this is going to become my go-to shirt for every outdoor adventure!

Loved this wool shirt. Super soft lightweight and the COLOR love it.

This is such a nice and comfortable lightweight baselayer shirt! I wore it while hiking in the Italian Dolomites and it kept me just warm enough in the cool moments and plenty cooled in the hot moments. Super soft texture and really breathable, I didn’t notice my sweating all day. The sizing fits true with a tighter fit—I’m usually a Medium and got a Medium and it was perfect. if you want extra tight I would size down but I thought it was comfortable and looked great.

This top is perfect for cool spring runs. The color is beautiful. The fabric is soft but breathable. I need to buy all the colors!

I wear this tee running and it’s super comfortable even in warm/humid conditions. The fabric is light, breathable, and good quality. I like that it’s not too thin so even a light color has good coverage. I was surprised at how well I liked the slightly longer sleeve. At 5’4 140#, the medium was a good fit for me.

I’ve gone through so many running shirts that stink after just one workout, but this one doesn't. The merino blend handles sweat like a pro and stays fresh way longer than my old polyester tees. It’s high-quality but doesn't look too 'sporty,' so I can easily wear it for errands after my run. Also, the Light Gray is such a beautiful, classic neutral—it goes with everything!

Love the lightweight feel of this tshirt, feels
Great to work out without weighing me down and is so breathable without any stink!
Also smart enough to wear just as casual wear.

Finally found my holy grail for summer training. I’m 5’6”, 140 lbs and went with a Medium for a bit of extra breathing room. Whether I’m lifting or running, this tee feels incredibly soft and stays bone-dry. But honestly, the real win is the odor control. It DOES NOT smell. Most of my other performance tops are basically disposable because they smell so bad after a hot run, but this one is magic. I’ll be buying more colors for sure.

I can’t get over how soft these are, almost like a second skin. They’re super breathable and didn't get itchy or smelly even after being out all day in the sun. This Light Pink is such a dreamy color! I’m so happy with it that I’m already thinking about getting the Light Blue too.

I usually avoid wool in summer because I assumed it would feel warm, but this completely changed my mind. The fabric is airy, soft, and surprisingly cooling once you start moving. It still felt dry and fresh even after a long walk in the heat! The color options also look much more elevated than standard gym shirts.

I’m 5’5”, 118 lbs and ordered a Small. The fit is really flattering without feeling tight, and the fabric stays cool and breathable even on warmer afternoons. I got the gray one and honestly love it even more in person — it looks clean, soft, and really polished for such a lightweight tee. I’ve also been taking it on trips since it doesn’t hold odor the way most workout tops do. Super easy piece to wear all summer.

Honestly impressed by how comfortable this tee feels in hot weather. It’s lightweight without being see-through, and the merino knitting texture keeps it from getting that damp, sticky feeling after workouts. I’ve worn it running, hiking, and even casually with jeans. Definitely feels more premium than typical athletic tees.

I tried this merino lightweight tee and it quickly became one of my favorites for running. The fabric is incredibly soft, lightweight, and doesn’t get clingy when I sweat.

I’m 5’6”, 130 lbs and went with a size M for a slightly relaxed fit. The light blue color is perfect for summer and looks even better in person.

Definitely recommend it if you want a running tee that feels airy but still polished enough to wear casually too.

Bunches awkwardly where the back where the neckline has an additional seam. Snags easily.

Very lightweight and comfortable. I wish there were more colors available, but performance-wise it's excellent!

Love the fit and the wool material not so thin

The fabric is amazing, and this Light Blue is the perfect shade for summer!

Lightweight without feeling flimsy. Looks polished enough for errands but performs great during workouts too.

Super lightweight and breathable! I ordered a Small and the fit is spot on.(I'm 5'4'', 110 lbs for your reference.)

This tee dries incredibly fast. I wore it for a sweaty run and still felt fresh afterward!

Beautiful color and very comfortable, perfect for hot-weather workouts.
