Soak this PastSky wrap in water for three minutes to activate its polymer beads and deliver adjustable hot or cold relief exactly where your back, knees, or shoulders need it. - Freeze the 58×35 cm grid-cell design for 1–2 hours to obtain extended cooling from solid cells that reach temperature faster than standard gel packs. - Microwave the vented surface for 2–3 minutes when you prefer soothing heat, with the air vents reducing pressure buildup for safer warming. - Wrap the flexible multi-cell structure around your body and fasten it with the two 78 cm elastic straps for stable, hands-free compression during work or recovery. - Re-soak the biodegradable polymer and fabric layer after moisture evaporates to restore full function and reuse the pack for ongoing hot or cold sessions.
