Material Science Verification

Independent ASTM D737 testing confirms 89.7 CFM airflow permeability – 53% higher than cotton underwraps . The PU foam structure demonstrates 0.02g/cm³ density with 300% elongation capacity (ISO 1798), preventing constriction during muscle expansion . Skin patch tests (ISO 10993) show zero allergic reactions in 98% of participants with adhesive sensitivities . Tear resistance tests reveal 1.2N hand-tear force threshold – 67% lower effort than industry average .

Sports Medicine Benchmark

Versus silicone-based underwraps, this prewrap maintains 92% adhesion after 120min sweat exposure where competitors slip . Compared to woven cotton, it reduces tape removal skin trauma by 78% (per JAMA Dermatology friction coefficients) . The 0.8mm thickness provides joint mobility preservation scoring 9.2/10 in athlete range-of-motion studies .

Professional Application Protocol

Joint Prep: Apply 50% tension spiral wrap starting distal to proximal . Taping: Overlap 30% when applying adhesive tape over prewrap . Hair Securing: Use 2-layer wrap with crisscross pattern at hairline . Sweat Control: Replace every 90min during high-perspiration activities .

Athletic Trainer FAQs

Q: Safe for tattooed skin?
A: Yes – non-adhesive formula prevents ink degradation .

Q: Maximum continuous wear time?
A: 8 hours; remove during sleep to maintain skin integrity .

Q: Hair type compatibility?

Sports Clinic Verification

“After 18 months treating 200+ athletes weekly, this prewrap became our go-to solution for sensitive skin cases. It eliminated the blistering we saw with traditional latex underwraps – especially important for our diabetic patients with poor wound healing. The tear strength is perfect: new interns can rip it cleanly without overstretching, unlike cheaper foams that disintegrate. Only limitation: avoid combining with oil-based analgesic creams as they degrade the PU foam’s integrity. For sports medicine pros needing reliable skin protection during dynamic taping, this outperforms brands costing triple the price.”
