Core Tank – Men's

Built for high-output training in the heat, the Core Tank is our go-to sleeveless layer for runners and gym athletes who want zero interference. The same moisture-wicking fabric from On's Core Tee pulls sweat off your skin fast, while the sleeveless cut keeps your shoulders completely unrestricted.

• Moisture-wicking fabric moves sweat away fast — built for hot, humid training sessions and high-output efforts
• Sleeveless cut gives your shoulders full range of motion with no fabric fighting your stride or lift
• Soft-touch material stays comfortable against skin during long sessions and won't irritate under a pack or vest
• Works equally well on the trail, track, or in the gym — relaxed athletic fit and classic crew neck keep it versatile
• Available in White and Gourami — two clean, easy-to-pair colorways that work with any kit
