A braced midline
Every barbell cue comes back to the midline. Pelvic-floor support gives your brace a foundation instead of asking your abs to do all of it.

Compression Shorts Built For CrossFit
Squat, snatch, run, row, repeat. The Lock's patented 'D Band' supports the pelvic floor so your midline stays braced from the first lift through the last round of the metcon.
Why It Works
What crossfit demands of your core
The patented "D Band" supports the pelvic floor and locks the core — the foundation every other movement is built on.
Under load and under fatigue
Heavy squats and high-rep cleans both punish the pelvis. Support keeps position honest when the reps start hurting.
Built for mixed modal
One garment that works for lifting, running, rowing, and gymnastics — no seams digging in on the rig or the bike.
Dry through the metcon
Active Cotton moves sweat and resists odour, so back-to-back sessions don't leave you soaked, sticky, or chafed.
In Their Words
"As an athlete I've tried many compression pieces, yet they do not live up to The Lock. Squatting with The Lady Lock has really made a difference — I focus more on stabilizing my core because of the fit and compression around the mid-line. I feel more secure and stronger. I do not squat without it."

Lock Apparel Active Cotton and The Lock — Gear Review
The Technology
Patented, not just tight
The same platform every crossfit 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.
"Lock Apparel's Lock supports the pelvic floor region and prevents you from losing pelvic floor stability — which, in turn, helps you lift and move better. Like a glass of water or a pair of running shoes, The Lock is that relevant."

"I'll keep this simple. Once you train and compete in The Lock, you just feel stronger, meaner, more centered and tighter. Keep these away from my competition — I want the edge to myself."

"Every stride translates more force into the ground. I stopped feeling my hips fatigue at mile 18. The Lock keeps my core and pelvic floor stable the whole way — that's the difference between finishing strong and just finishing."
