Jr. Uni-Vest — Adjustable Weighted Vest for Young Athletes (21 lbs.)
Built for young athletes, ages 10–15+ (50 to 120+ lbs., 20–40+" waist), the New Jr. Uni-Vest is a smaller version of LaceUp's durable Uni-Vest Professional — the same vest trusted by police, military, and sports teams for strength and endurance training.
Why athletes and parents love it:
- Contours to the body — The ultra-thin Contour-Fit design bends and moves with the athlete, so weight stays close to the core and never throws off balance.
- Safety-first construction — A 2mm inner padding layer plus a 10mm outer padding layer protect the athlete (and anyone nearby) from bumps and falls.
- Built to last — Nylon laminated to foam padding stands up to years of hard training. Wipe clean easily, or machine wash with weights removed.
- Secure, no-slip weight pockets — Stretch-Fit inner pockets hold FLX Weights snugly in place — no velcro or hardware needed, so nothing shifts, loosens, or falls out.
- Custom fit for growing athletes — The Double-Lock belting system adjusts from a 20" to 40"+ waist, expanding and contracting comfortably as the athlete breathes and moves.
- Fully adjustable weight — 20 double-size pockets hold 1–2 half-pound weights each. Ships at 9 lbs. (1 lb. shell + 16 weights) and adjusts from 1 to 21 lbs. in half-pound increments.
Great for: Basketball, volleyball, lacrosse, soccer, baseball, track, and gymnastics — plus balance training, physical therapy, or improve core and postural strength.
A note on safety: Wearing weight is a form of resistance training. Please consult a doctor before starting any weighted training program, use under professional supervision, start light, and increase gradually. Balance the load evenly between front and back, filling from the bottom row upward.
