Rotation from a locked base
Hitting and throwing are hip-driven. Supporting the pelvic floor gives your rotation something solid to turn against.

Compression Shorts Built For Baseball
Every swing and every throw is a rotation that starts at the hips. The Lock's patented 'D Band' anchors the pelvic floor so that rotation turns into bat speed and arm speed instead of leaking out of an unstable base.
Why It Works
What baseball demands of your core
The patented "D Band" supports the pelvic floor and locks the core — the foundation every other movement is built on.
Explosive out of the box
The first three steps down the line and the first step in the outfield both come from the same place — a stable pelvis.
Long days, no chafing
Doubleheaders, bus rides, and sliding pants add up. Active Cotton stays dry and quiet against the skin instead of sticking.
Protected and held in place
The Lock holds the anatomy safely and comfortably, so nothing shifts on a slide, a dive, or a full-effort swing.
In Their Words
"I tried the Lock underneath my uniform and it definitely made a difference in the field, but more importantly at bat. Having a stable core when going after pitches is completely fundamental. My swings are more consistent and my average is up 30 points. The shirts keep me cool in the heat and warm in the cold without any chill or stick, and they don't stink. Both products — 5 stars."

The Technology
Patented, not just tight
The same platform every baseball athlete on this page is wearing. You only need to wear The Lock once to feel the difference that separates it from any comparable short on the market.
The D Band
A patented band that supports the pelvic floor and holds the anatomy safely against the pubic symphysis — stability where compression alone does nothing.
Differentiated fabrication
The panels distinguish between muscle groups, so support lands where it's needed and freedom of movement stays where it matters.
Active Cotton
100% cotton engineered to move moisture away from the skin, resist odour, and stay soft without going heavy, sticky, or cold.
More Athletes
Same platform. Different arenas.
"I've only ever worn the big synthetic brands — they get baggy and smelly. When I tried The Lock I was blown away at how dry it stayed even after a long workout or a 90-minute hot yoga class. The breathable material allowed my legs to have better range of motion, even late in the workout. The anatomical support is why it's patented."

"Lacrosse is like running a long-distance race — but you're twisting and turning to get position or shoot, and that means your core has to be engaged. That's what The Lock does over just regular compression shorts. I've also noticed faster recovery the next day."

"As an ex-Olympic hurdler, I'm amazed that a pair of running shorts could actually enhance my performance. After only 2 weeks the small aches and pains that are just part of being an athlete have miraculously disappeared. The Lock is truly a performance-enhancing piece of gear that every athlete should add to their arsenal."
