ThrowTech Sports

ThrowTech Sports Asymmetric thermal compression shirts engineered to protect the throwing arm. Made in the USA. Throw harder. Recover faster. Protect what matters.

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 throwing-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

Developed in partnership with the Vanderbilt University Baseball Program and endorsed by Scott Brown, Lantz Wheeler, and Bryce Denton.

Your arm has a limited number of throws in it. Nobody knows the number - you only find out when it runs out.
Most arm injuries aren't one bad throw. They're accumulation: throwing cold, throwing tired, throwing year-round without protecting the muscle chain doing the work.
You can't add throws to the tank. You can protect the ones you've got.
Warm up right. Recover right. Keep the arm warm between reps.

Softball arms take the same abuse. Sometimes more.
Doubleheaders, short turnarounds, infield throws all day from cold morning games to hot afternoon ones. Nobody talks about softball arm care - we designed for it from day one.
Left- or right-handed. Same full-chain protection.

Cold muscles and hot days need different shirts.
That's why there are three: Cold (25-45°), Cool (45-70°), and Warm (70-100°). Full sleeve for cold weather, 3/4 for summer. The stitch color tells you which one you're holding.
A February bullpen and a July tournament put completely different demands on your arm. Dress it accordingly.

Arm sleeves only cover half the problem.
Your throwing motion doesn't start at your bicep. It starts in your chest, fires through your shoulder and scap, and finishes at your elbow. That whole chain generates the throw - and that whole chain takes the stress.
So covering just the forearm is like stretching only one hamstring.
Look at the stitch line. It runs chest to elbow because that's where the work happens.

This is the ThrowTech Arm Protection System.
One continuous compression sleeve, stitched into the shirt from your chest, over your shoulder and scap, down to your elbow. Not an arm sleeve you pull on and hope stays put - full throwing-chain coverage that moves with you.
Three colors. Left- or right-handed. Baseball and softball.
Built in the USA for one side of your body. On purpose.

Ever notice big-league pitchers wearing a jacket in the dugout in the middle of summer?

It’s not about comfort. It’s about keeping the throwing arm warm between innings.

Muscles perform best — and strain least — when they’re warm. Every half-inning on the bench, that arm starts cooling down. The jacket keeps the whole chain — chest, shoulder, elbow — warm and ready to fire again.
The pros treat arm warmth as protection. Youth arms deserve the same.

Save this for your next early-morning tournament.

We brought back a product parents kept asking about.
In 2017 our family built a shirt to protect young throwing arms. Life got in the way, and it sat dormant.
But parents kept asking where to get one. So this year, we brought it back.
ThrowTech makes thermal compression shirts for baseball and softball players - with one difference you can see: the sleeve isn’t attached at the shoulder. It’s one continuous piece running from the chest, over the shoulder and scap, down to the elbow. The full throwing chain, not just the arm.
Made in the USA. Built for one side of your body. On purpose.
Follow along - this week we’re sharing why a warmer arm is a faster arm, and a safer one.

"You’ll see my MLB clients wearing them the next time you turn on ESPN’s Baseball Tonight. Genius idea. Simple product. Amazing results! The ThrowTech Sports™ pitching shirts are a no-brainer. There’s so many products on the market designed to strengthen and protect the arm. However, there’s only one that actually allows you to pitch without getting in the way. Best of all, these right and left handed shirts not only conform to the throwing arm and shoulder as a compression sleeve but serve double- duty by acting as climate gear to help protect your throwing side."
