Men's Woolverino Midweight Flyless Running Tights
Stay active through winter while everyone else is bundled up inside. These flyless running tights feature athletic styling that looks like sport leggings—not underwear—so you can wear them confidently as a solo layer or under shorts. The Woolverino core-spun construction combines merino wool's natural performance with nylon's durability for tights that hold up to serious training without sagging or bagging out.
Why You'll Love These Running Tights:
The extra-wide flyless design and extended gussets move with you through every stride, while the athletic seam placement gives you that sport-legging look. A small hip pocket (3.5" x 2.5") on the left side holds a card, cash, or keys—the essentials for a no-phone run. The covered waistband puts merino next to your skin at the waist, and flatlock seams prevent chafing during long miles. At just 0.5 lbs (size L), they're lightweight yet insulating. UPF 50+ protection shields your skin during sunny winter runs.
Why Core-Spun Merino?
Woolverino technology wraps a nylon inner core with Australian merino wool outer sheath. You get the strength, elasticity, and durability of nylon where you need it (to maintain the athletic fit) with the insulation, moisture-wicking, and odor resistance of merino against your skin. The 85% merino / 13% nylon / 2% spandex blend delivers three-season performance—warm enough for cold morning runs, breathable enough to prevent overheating. Triple certified (OEKO-TEX Standard 100, Woolmark, and Responsible Wool Standard).
Size & Fit:
Athletic fit with skin-tight compression styling. Mid-rise waistband sits below the belly button. Runs true to size; size up if you prefer a looser fit. Model in black is 5'10" / 150 lbs wearing a medium.

Care Instructions:

Complete Your Look:
Pair with a Woolverino quarter-zip for cold-weather training, or layer under shorts with microweight tops for milder conditions. Browse our full merino wool collection for Alaska-tested running gear.
