When it comes to fit and general design, the IZI Body Cooling vest is aces; few vests look and feel this good. And the quality construction of this Dutch-designed apparel is a fantastic match—from the zippered pockets to the reflective ribboning to (urp) the price. The ultra-lightweight vest (only 1 lb 9 oz) also features a true hybrid cooling design, a combination of ice/gel and evaporative. Users initially charge the vest by soaking it in water for 10-20 minutes, which wets the vest and plumps the gel. After drying with a towel and/or a short time on the spin cycle in the washing machine, it can be worn immediately using its evaporative cooling although the vest will still be damp (see wetness footprint photo). For a more powerful cooling effect, carefully fold the vest and freeze it. Unlike the hydrogel vest from Polar and Arctic Heat, this cooling pods on this vest are attractive even in their frozen state, although like those other two vests it may take some cajoling to fully open in order to wear. This, however, highlights the vest’s critical shortfall and why it earns the lowest endurance score in our testing.
The IZI, although it gets exceptionally cold (as low as 34 °F in our safety tests), thaws extremely rapidly, lasting no more than 45 minutes during moderate exercise in a controlled environment. At that point, virtually 100% of cooling power is generated by evaporation, which is largely ineffective in humid climes. That said, the evaporative effect can last days, a full 72 hours according to IZI, and our tests confirm that. Unfortunately for those with multiple sclerosis, that may not be enough to meet cooling needs. For short-term cooling, especially in the sporting arena, the IZI hits on all cylinders and, in arid climates at least, still provides a punch hours after the cooling elements have thawed.
