Does this shirt itch when I sweat?

No. While traditional heavy sweaters often cause skin irritation during active use, this shirt is designed to stay comfortable even when you sweat. Its ultra-fine 17.5-micron fibers feel smooth against the skin and are intended to minimize the scratchy sensation that can occur with coarser fabrics, even when the fabric is soaked.

Can I wear this under a heavy backpack?

Yes. The specialized Woolverino fabric construction wraps soft Merino fibers around a strong nylon core. This unique core-spun method drastically increases the tear resistance of the lightweight material. In addition, the fabric withstands the constant rubbing of heavy pack straps during long wilderness treks.

How often do I need to wash it?

The natural structure of Merino fibers absorbs moisture while locking away odor-causing bacteria. You can wear this garment for consecutive hard workouts before noticing any smell. Simply hang it up to air out overnight and put it right back on the next morning. This drastically cuts down on your weekly laundry loads.

Are the materials safe for my skin?

We prioritize your health and environmental safety. This garment earns the strict OEKO-TEX Standard 100 certification. Independent testing labs evaluated the fabric to guarantee it contains zero harmful substances. This guarantees that you get a pure performance layer completely free of PFAS and toxic chemicals.
