HARNESS FIT & REQUIREMENTS
RAFlex harnesses anchor from the upper back (T1–T12
thoracic zone). The back panel must sit between the
shoulder blades at all times — not at the waist or neck.
Applies to all variants: Figure-8, vest, yoke, and racerback.
Weight limits:
• Up to 100 kg / 220 lb — approved for use.
• 101–120 kg / 222–264 lb — use with caution. Inspect skin
after each session. Not recommended for high-velocity
striking.
• Above 120 kg / 264 lb — DO NOT USE. Contact RAflex
for larger variants.
MANDATORY FIT CHECK — BEFORE EVERY
SESSION
• Tighten straps until back panel cannot shift on a torso
twist.
• Raise both arms into a guard or athletic stance.
• Confirm tube exits below armpit with at least 1 cm
clearance.
• If tube contacts armpit, loosen front closure one notch
and re-check.
• If loops slide or panel sags, tighten one notch.
• If tube still contacts armpit at maximum looseness, stop
use and contact RAflex.

SETUP GUIDE — STEP BY STEP
• Step 1 — Harness: Put on like a vest. Back panel between
shoulder blades. Tighten until panel cannot shift on a torso
twist.
• Step 2 — Ring Selection: Choose your snap hook ring size:
20mm ring if you are 5'5" (165 cm) or taller. 50mm ring if you
are under 5'5" (165 cm). The ring is fixed directly to the wrist
strap — no separate carabiner needed.
• Step 2 cont. — Band Attachment: Attach the paracord from
the band directly to your snap hook ring. To adjust resistance,
pull the paracord knot through the ring and re-set at your
chosen node. Knots can be re-tied to a new position at any
time.
• Step 3 — Wrist Cuff: Thumb through loop first, then secure
forearm Velcro. Prevents rotation under tension.
• Step 4 — Leg Strap: Wrap around upper thigh. D-ring must
face outward (lateral) to avoid catching opposite leg during
footwork or strikes.
• Step 5 — Resistance Nodes: Pull paracord through snap
hook ring to chosen node (40 mm intervals). Start at Node 1
and progress gradually.
• Step 6 — Back Routing: Thread tubes through nylon ring
guides on back straps. The back ring is attached to the harness
via two eyelet holes — paracord from the bands connects to
this ring on the rear. Do not train if any guide stitching appears
loose or torn.
n INFO — Chest strap packages: If your package includes a
chest strap (secondary strap), the ring can be transferred to the
chest strap if preferred. Not all packages include a chest strap.
PRE-SESSION INSPECTION — 90 SECONDS
Check all 7 points before every session. Do not skip.
• 1 — Latex tube (5 mm ID / 10 mm OD / 250 mm unstretched):
Cracks, punctures, nicks, dry patches, or whitening. Fail =
replace immediately.
• 2 — Clamps: Must be uniformly crimped, undeformed, and
tightly fixed around the core bundle.
• 3 — Ball stoppers: Seated against clamp. Retire only if ball has
visibly migrated significantly.
• 4 — Paracord loop (4 mm): Intact braid, no inner core visible.
Pull-test minimum 15 kg static before attaching to snap hook
ring.
• 5 — Containment sleeve: Heat-shrink smooth, fully sealed, and
no peeling over hardware.
• 6 — Soft components & snap hook ring: Strap stitching, Velcro
adhesion, foam padding on wrist and thigh cuffs. Snap hook
ring must be firmly fixed to wrist strap with no play or
deformation.
• 7 — Routing rings & back ring: Nylon loops intact and stitched
tight. Back ring secure in two eyelet holes. Tube passes cleanly
inside each ring.
QUICK-START SUMMARY
• 1. Back panel between shoulder blades. Cinch
completely rigid before use.
• 2. Select ring size: 20mm if 5'5" (165 cm) or taller. 50mm
if under 5'5" (165 cm). Snap hook ring is fixed directly to
wrist strap.
• 3. Attach paracord directly to snap hook ring. No separate
carabiner needed.
• 4. Tubes through all nylon routing rings on back straps
every time.
• 5. 90-second inspection before every session. No
exceptions.
• 6. Body-to-body only. Never anchor to any fixed structure.
• 7. Stop immediately on any crack, pop, tension shift, or
tube migration.
• 8. Retire all latex at 12 months from first use regardless of
appearance.
