Wear more, wash less
Alpaca wool naturally resists odor. Air your layer between wears, then wash it when it needs cleaning. Less time doing laundry. More time outside.
Cover your arms with our featherweight knit. This men's long-sleeve T-shirt uses 110 g/m² Alpaca wool fabric for warm days, light activity, and a low-bulk first layer.

Your layer starts with Alpaca wool from Peru. Its smooth fiber surface gives the knit a soft feel, while the knit structure allows air to move through as you do.
Long sleeves cover your arms in a light knit that works on its own or under another layer.
At 110 g/m², this is our featherweight knit. Choose it for light activity and wear that avoids repeated rubbing against rough surfaces.

Designed and made in one country
Arms of Andes is a family company with roots in the Peruvian Andes. “Arms” brings together the initials of four siblings. That connection to Peru shapes what we make and where we make it.
From fiber sourcing and yarn spinning to knitting and sewing, production stays in Peru. One country, with the people and knowledge behind your gear close together.
Best base-layer for cooler days, it fits well under a short or long sleeve T-shirt and punches way above it's weight in heat-retention. Plus, it has incredible breathability and is antimicrobial as well.
Extremely soft! It was warm and yet I never felt like I was wearing thermal clothing. I will buy more.
