    PATENTED CORE STABILITY

    The Only Short
    That Locks Your Core

    Worn by Olympians. Engineered in Canada around one patent that changed what an athletic short can do for the human body.

    01 / 06 · Lock Technology

    Three Pillars. One Patent.

    The most impactful piece of
    sports clothing of our time.

    01

    Core Support

    The D-Band locks your hips and stabilizes your core in three directions, so power transfers from torso to ground without leaking.

    02

    Pelvic Floor Stability

    The only short that physically lifts and supports the pelvic floor — putting your hips in the right position for winning.

    03

    Complete Leg Freedom

    Support where you need it. Freedom where you don't. Your legs stay unrestricted to be the most explosive they can be.

    The Technology

    Patented Lock Technology

    Core and anatomical support through smart engineering — for both sexes.

    The LOCK™ and its patented "D Band" gives core support for both sexes. For men it supports the male anatomy, stomach and lower back while allowing freedom of movement; for women it supplies hip-hugging, butt-lifting engineering along with tummy and lower back support.

    Both versions use specific fabrications engineered to differentiate between muscle groups — allowing maximum support, maximum comfort, and enhanced performance while reducing minor aches and pains.

    The combination of unique fabrics and engineering makes the patented LOCK™ exclusive core support completely different than any other product on the market. Unlike compression shorts, they do not sag when they become wet or restrict your stride. The result is a more centered athlete with a stabilized core.

    Centre Yourself. Stabilize Your Core.

    You'll have more strength, more power, more energy, more freedom to move, to workout, to strike. Ask any ballet dancer, yogi, martial artist, even weight trainers and they'll all tell you the same thing: when you are centered and stable, you are a force. You'll perform better, last longer, recover faster.

    Yusuf Omar, President & CEO of The System, describes it this way:

    "The Lock supports the pelvic floor region and prevents you from losing pelvic floor stability, which in turn, helps you lift and move better. The Lock Core Compression Short, for men and women is a first of its kind. It's a garment, but think of it as a patented, engineered piece of equipment. For men, it holds all your anatomy in place so your hips, stomach and core are secure. For women, it pulls your tummy and hips in tight to your core, yet both versions leave your legs free."

    Try the Patented Lock Technology for yourself and see what your potential really is.

    PATENTED CLOTHING TECHNOLOGY

    HOW IT WORKS.

    01

    The D-Band

    A strong, engineered band of fabric runs along the waist and locks the garment to your hips — the anchor for everything else.

    02

    Pelvic Floor Lift

    The D-Band continues underneath the crotch, lifting the pelvic floor into its natural, powerful position.

    03

    CORE STABILIZATION

    With the hips locked and the pelvic floor supported, the core is stabilized in 3 ways, giving you the freedom to move through your legs to be the most explosive you can be, still while you're centered and stable.

    Why Compression Isn't Enough

    Every other short
    squeezes. The Lock supports.

    Standard compression shorts apply one type of pressure — they squeeze the legs. That's it. They do nothing for the core that drives every stride.

    The Lock

    The Patented Difference

    Three-Dimensional Support

    • Multi-zone support: hips, pelvic floor, core
    • Patented D-Band lifts and stabilizes
    • Legs stay completely free to fire
    • Engineered for the actual mechanics of running

    Regular Compression Shorts

    One-Dimensional Squeeze

    • Single-axis squeeze on your legs
    • No core or pelvic support
    • Restricts stride at the hip
    • Marketed as 'performance' — but only compresses

    Basketball athlete
    Basketball
    "The first thing I noticed was that my stability improved. I was able to dribble, stop and shoot with more control. That led to overall more confidence as I moved around the court. But the biggest benefit was late in game or practice when I got tired. I found that I didn't lose control and that I recovered quickly. Great product unlike any other compression shorts I've worn — and I've worn them all."

    "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."

    "I love Lock Apparel's Active Cotton because of how it feels against my skin. During summer training, the breathability made me feel cooler and less sticky. I really enjoy the fact that there is no odor. I am basically incapable of wearing anything else now that I know what Active Cotton feels like."

    "The Lock supports my core securely without sacrificing comfort — light, durable, dry through every workout, and zero restriction in my movement. As a boxer it's tough to find tops that fit around your shoulders without restricting your punches. Active Cotton doesn't get wet, sticky or heavy. Lock Apparel lives up to its hype and is 100% worth it."

    "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."

    "As a figure skater my body temperature goes up and down on a regular basis, training in a cold arena for many hours. The Active Cotton kept me comfortable and warm, almost like a windbreaker, and then cooled me down just as quickly. It didn't restrict my movement in any way — I had full range of motion to perform at my fullest."

    "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."

    "From spike serving to defence and passing, The Lock keeps you stable. The core compression aspect keeps your back and hips engaged so your upper body can perform. It's also helped my lower back from the tiny aches of repetitive drills. Once you get used to it, regular compression just doesn't measure up."
