The PerformaWool Aero Weight Tee is a MUST HAVE!

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!

nice and comfortable lightweight shirt!

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.

Perfect for spring runs!

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!

Super Comfortable!

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.
