hrowTech Sports builds performance apparel for one purpose: to protect and elevate the throwing athlete. Every shirt we make is engineered around a single insight — pitchers and position players don't use their bodies symmetrically, so their gear shouldn't be symmetrical either. Our proprietary unibody compression sleeve is stitched directly into the chest as one continuous piece, wrapping the thr
owing-side shoulder, scapular muscles, and arm in high-density thermal compression. The non-throwing side uses lighter materials to reduce heat buildup and preserve full range of motion. The result: targeted warmth and circulation where it matters most — supporting the muscles, tendons, and ligaments that take the highest load on every throw. For parents and coaches who understand the cost of UCL injuries, Tommy John surgery, and rotator cuff damage, ThrowTech is preventative arm care built into the baselayer. Three shirts for every condition:
• Cold (25–45°F) — full sleeve, maximum thermal protection
• Cool (45–70°F) — full sleeve, balanced warmth
• Warm (70–100°F) — three-quarter sleeve, lightweight thermal compression
