Terrific shirt. Light weight yet warm. Good fit and washes well.

Me gusta mucho por cómo regula la temperatura corporal. No da demasiado calor ni frío. Es ideal para esas noches frescas y aparte no sudas nada en ella. No huele nunca y los calcetines también son una pasada. 🩷

These wool undergarments take comfort and support to a new level. Not only do they feel great(after a solid hike they are comfortable) but they breathe enough to prevent a swampy jungle. Few undergarments can caress your package without getting a bit personal, well I can say that these won't be riding up your canyon while they keep your eggs inline. All in all I will be ordering more and probably going to "ruin" Christmas by getting everyone these instead of the new whatever well be asked for!

Seems to be a quality product. Fit is “athletic” and runs about true to size maybe a little small in the arms and belly. I wear a Medium in Smartwool and this fits a little tighter. Breathable and durable.
