The INUTEQ Bodycool Hybrid 2-in-1 Vest serves as pre- or post-cooling gear for a variety of athletic activities. The cooling fabric can provide comfortable cooling for up to 28 hours. INUTEQ-PAC-PCM cooling packs must be ordered separately; with these, a constant temperature of 6.5° C or 15° C can be maintained for 1.5 - 2.5 hours. The vest's exterior is made of 100% polyester, with a core of INUTEQ-H2O® superabsorbent fabric with antibacterial treatment. The liner is 100% polyester with PU coating, and the pockets are also made of polyester. It has 2 front and 2 rear pockets for the cooling elements, and a front zipper for easy wearing. Lightweight, non-toxic, durable, and machine washable, the vest activates by soaking it in water for a maximum of 2 minutes and gently wringing out the excess water. To activate the INUTEQ-PAC, cool it in the refrigerator before placing it in the vest. CE marked.
