1. Keep Your Ice Bath Cold for Longer - 8 lb Ice Blocks provide extra large cooling for the Plunge Lab, melting gradually to maintain low temperatures for extended periods. This supports faster recovery after workouts and helps alleviate muscle soreness. An essential accessory for any Ice Bath Tub or Portable Cold Plunge Tub owner. 2. Thickened Silicone Mold with Lids - The lid prevents water from spilling in the freezer during freezing. Thickened silicone offers enough support to maintain its shape while the water freezes, preventing deformation or breakage under the weight of the large ice block. Durable enough to outperform small bread pans, plastic ice trays, and Ziploc bags. 3. Foldable Extra Large Ice Mold - Made from 100% food-grade silicone, safe and healthful. Foldable design for convenient storage and transport. The trapezoidal shape and polished non-stick surface make releasing ice blocks effortless. Silicone is non-toxic, does not release chemicals into water, irritate skin, or harm the environment. 4. Save Money & Save Time - No need to purchase ice again. Extra large ice block molds store easily in your home freezer, reducing trips to the store. 5. Use Scenarios - Post workout recovery at home: use the 8 lb ice blocks in your Plunge Lab for extended cold exposure to ease muscle soreness after intense training. - Training blocks or competitions: maintain longer cooling sessions in cold plunge therapy for sustained recovery. - Travel or portable setup: foldable mold enables preparation and storage of blocks at home, ready to use with a portable cold plunge tub when you are away from home.
