YOU READ THE INGREDIENTS.
READ THE LABEL.

You track your protein. Question your food. Train with intention. Think about your recovery. But when was the last time you checked the fabric against your skin?
YOU UPGRADED EVERYTHING ELSE. NOW UPGRADE YOUR SHORTS.
01 / MATERIALS

POLYESTER IS PLASTIC.

MERINO IS NATURE.
Most gym shorts are manufactured from petroleum-derived synthetic fibers. Polyester is durable and inexpensive, but synthetic textiles can shed microplastic fibers during washing and wear. Merino wool is a natural protein fiber with a different approach to comfort.
QUESTION THE FABRIC. NOT JUST THE BRAND.
Charcoal grey merino wool shorts – lightweight, breathable performance wear for gym and travel
02 / OPEN QUESTIONS

WHAT'S HAPPENING BELOW THE BELT?

THE RESEARCH IS STILL DEVELOPING.
Scientists have detected microplastics in human reproductive tissue, including testicular tissue. Researchers are investigating potential effects on reproductive health. There is currently no established evidence that wearing polyester gym shorts directly lowers testosterone or causes infertility.
View research referencesHu et al., 2024. Microplastic presence in human testis and its potential association with sperm count and weights of testis and epididymis.
Leslie et al., 2022. Discovery and quantification of plastic particle pollution in human blood.
Research on health effects and routes of exposure is ongoing.
YOU CAN MAKE MORE INTENTIONAL MATERIAL CHOICES WITHOUT WAITING FOR EVERY QUESTION TO BE ANSWERED.

03 / NATURAL PERFORMANCE

BUILT TO BREATHE.

NOT JUST TO LOOK ATHLETIC.
Merino wool naturally manages moisture vapor, helps resist odor buildup, and can buffer temperature changes. Comfort that transitions from movement to recovery.
EXTRA-FINE MERINO. NATURAL COMFORT. SERIOUS MOVEMENT.
BUILT TO BREATHE.
04 / BEYOND THE GYM

TRAIN HARD. LIVE NATURALLY.

ONE PAIR. MORE POSSIBILITIES.
From lifting to post-workout recovery, travel, and everyday lounging, ROANHORSE merino wool shorts are designed for movement and comfort beyond the gym. For high-heat environments such as saunas, follow facility rules and the garment's care instructions. Do not use apparel as protection from heat risk.
GYM. RECOVER. TRAVEL. LIVE.
TRAIN HARD. LIVE NATURALLY.
05 / RADICAL TRANSPARENCY

NO GREENWASHING.

READ OUR LABEL TOO.
ROANHORSE prioritizes extra-fine merino wool against your skin. Functional synthetic components remain in areas including the waistband and zipper construction. The design is intended to keep plastic-containing materials from touching the skin during normal wear.
PLASTIC-FREE SKIN CONTACT WHERE IT MATTERS.
NO GREENWASHING.
