Interchangeable!: Each Core option has the same footprint and/or width as every other Core option making each completely interchangeable without switching or changing Connector belts or length. Every Connector belt is completely interchangeable as well, which means one combination or configuration may be used for training and another for race day. Because there are currently eight different Core options and five different Connector options, that allows for 40 different combinations. We want you to rock!
How to Choose & Assemble Your Molecular Belt System ( MBS )
Step 1: Choose a MBS Core option – each with the same footprint but equipped with a range of choices. Base your decision on the level and duration of your activity, hydration, support and supplement needs. The Core piece will typically be worn posterior ( rear of waist ).
Step 2: Choose a sized MBS Connector belt, typically worn anterior ( front of waist ) based on your waist or hip measurement. Don’t worry about the width of the MBS Core piece, it’s been included. Base your choice of connector belts on additional personal support needs. Ask yourself: “What else do I need and want to take with me?” Choose the Connector that fits your answer.
Step 3: Size and simply assemble MBS Core with the MBS Connector belt. Locate the red Speed Hook, an aluminum hook specially designed to be adjustable and nonslipping and attach it to the loop on the left side of your MBS Core.

What Makes our Waist Packs, Waist Bags and Waist Hydration Belts / Holders / Carriers with Bottles Better?
1. Comfort: Redesigned basics to really fit the human body—in all its shapes and sizes! The result is Human Contoured Belts, Vests and Packs designed to enhance performance without binding, impeding or inhibiting freedom of movement. The belly is now liberated from a buckle and that extra space used more comfortably, conveniently and effectively.
2. Fit: Proper fit enhances Comfort. Holsters, pockets, and other access points should be positioned correctly no matter the size of the wearer. When practical, pieces have been sized to achieve a second skin, not too tight and not too loose. Balance is maintained for weight distribution. Compressi-flex™ provides just enough give while maintaining gentle, stabilizing, compression without impeding body function, movement or freedom.
3. Ease of Use: Proper fit aids easy usage. Properly positioned holsters, pockets and other stowage is essential for smooth access of utility even from storage located at the back. With properly angled and designed holsters, snap back magnetic closures and other features, one-handed operation is all that’s required. As to adjustments, once it fits, why futz with it again? Adjust Velcro side once, then speed hooks provide for rapid entry and exit.
4. Function: Ease of Use assists in a high level of functionality particularly when the level of functionality is heightened by well designed features such as the Body Rhythm Harness, Compressiflex attachment points, Polarity System equipped hydration systems, MBS system which includes interchangeable management, speed hooks, and body shaped contoured belts and vests, and even small, bounce-less, noiseless, zipper-pulls that are easy to grab even with tired swollen hands or while wearing gloves.
