SAP Hot & Cold Knee Wrap – Reusable Microwave & Freezable Brace

Meet the Hailicare Self-Absorbing SAP Knee Wrap — a versatile, reusable hot and cold therapy wrap designed for athletes, active individuals, and anyone who wants targeted temperature support for their knee. Powered by Super Absorbent Polymer (SAP) technology, this innovative wrap delivers even, long-lasting warmth or cooling for up to 30 minutes per session.

Made in Mainland China.

Why Choose the Hailicare SAP Knee Wrap?

• Dual-Mode Therapy: Use as a cold compress (freeze for 1–2 hours) to help reduce post-sport swelling, or as a hot compress (microwave for 2 minutes, flipping halfway) to promote circulation and ease stiffness.
• Even Temperature Distribution: Unlike traditional gel packs that develop hot or cold spots, the SAP inner layer stores and conducts temperature uniformly across the entire knee surface.
• Self-Absorbing Technology: The polymer resin core absorbs water on its own, forming a stable gel that holds temperature longer — no messy filling required.
• Leakage-Free Design: No liquid gel means no drips, no mess. The wrap stays intact whether frozen solid or heated in the microwave.
• Skin-Friendly Materials: The outer layer is crafted from smooth, high-density polyester fabric that is water-resistant and stain-resistant for easy cleaning. The inner SAP resin is odorless, biocompatibility-tested, and safe for direct skin contact.
• Versatile Use: Ideal for knee support after sports, post-surgery recovery (switching from cold to warm as recommended by your care provider), everyday knee stiffness, and even abdominal warmth for menstrual discomfort.
• Secure Fit: Includes 2 elastic straps to hold the wrap firmly in place, keeping both hands free during your session.
• Reusable & Eco-Friendly: Made from eco-friendly composite fabric and water-absorbing polymer resin — built to last through hundreds of uses.

Frequently Asked Questions

Q: How long does the Hailicare SAP Knee Wrap stay cold or warm during a session?

A: The SAP (Super Absorbent Polymer) technology allows the knee wrap to maintain effective cold or warm temperature for up to 30 minutes per session — significantly longer than most standard gel ice packs, which tend to lose temperature quickly due to uneven gel distribution.

Q: Can this knee wrap be used on other body parts besides the knee?

A: Yes! While it is specifically shaped and sized for the knee, many users also use it on the elbow, shoulder, or abdomen. It is particularly noted for warm abdominal use to ease menstrual discomfort. The two elastic straps help secure it to various body areas.

Q: Is the SAP inner material safe for sensitive skin?

A: Absolutely. The inner water-absorbing polymer resin has passed biocompatibility testing and is certified odorless and safe for skin contact. The smooth, high-density polyester outer fabric adds an additional comfortable barrier between the SAP layer and your skin.

Q: How do I recharge the wrap for another session?

A: For cold therapy, simply return it to the freezer for 1–2 hours. For warm therapy, repeat the microwave process (1 minute each side). The SAP core retains its properties through hundreds of reuse cycles, making this a cost-effective and eco-friendly alternative to disposable ice packs.
