Andes-adapted for changing temperatures
Alpacas evolved where days run warm and nights turn cold. Their semi-hollow fibers trap insulating air, helping you stay comfortable as the temperature changes.
Give your first layer a little more room. These men's Relax Boxers pair a looser cut with 160 g/m² Alpaca wool fabric for everyday wear and days on the move.

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.
Choose this relaxed cut when you prefer more room than fitted boxer briefs provide.
The light knit lets air move through, giving you a comfortable layer as you go from everyday miles to a change of pace.

The benefits
Alpacas evolved where days run warm and nights turn cold. Their semi-hollow fibers trap insulating air, helping you stay comfortable as the temperature changes.
Alpaca’s smoother scales give the fabric a soft feel against your skin. Comfort comes from the fiber’s structure.
Alpaca wool brings breathable comfort to your first layer. Wash intimate apparel after wear to keep it clean; natural odor resistance doesn't replace regular care.
