If you have multiple sclerosis (MS), it’s likely that the sun and the heat are your foes.

Even a slight increase in temperature, something as little as 0.5°F (0.75°C), can worsen and agitate symptoms. Your MS symptoms may also get worse as a result of:

  • exercise or an overly active lifestyle
  • hot showers or baths
  • fever from a cold or other acute illness

In medical terms, this is known as Uhthoff’s phenomenon. Overheating was actually the basis for diagnosing MS prior to the use of MRI. Since a slight temperature increase can impair nerve impulses enough to cause symptoms, a “hot tub test” was once used to spur on symptoms.

While temporary, such small temperature increases can greatly impact your quality of life.

Cooling vests can help to maintain your core body temperature, prevent temperature fluctuations, and reduce flare-ups.

There are different kinds of cooling vests with varying price points and features. Battery- or electric-powered vests, called active cooling vests, can be more expensive but can cool the body longer. Gel pack or passive cooling vests don’t provide such long-lasting cooling, but they’re usually cheaper.

Before you purchase a cooling vest, take a look at the 10 models below.

1. Polar Products Cool58 zipper vest kit with vest, neck wrap, and extra packs

The vest gets high marks for its customizable fit and unisex design, and it’s appropriate for a variety of sizes, activities, and climates. It’s discreet and can be worn either over or under your clothes. It’s also machine washable.

Price: Around $100

8. Alpinestars MX cooling vest

Price: Around $60

Instead of cooling packs, you prepare the vest by soaking it in water for 5 to 10 minutes, then squeezing the excess water. It can keep you cool for several hours.

Lightweight and sporty, it allows for plenty of movement and looks more like a sleeveless T-shirt than a cooling vest.

When you’re really feeling the heat, you might want to add a few accessories to assist your cooling vest. Other times, you may only need a quick cooldown. Either way, there are lots of cooling products to choose from. Here are a few ideas to get you started:

Regardless of what type of vest you choose, make sure it fits you properly around the torso. A vest that’s too loose-fitting may not give you the desired effect.

Other features to consider include:

  • how long it’ll keep you cool
  • what’s involved in cooling the vest
  • how much it weighs
  • how it needs to be washed
  • whether it’s for passive or active pursuits
  • whether it can be worn over or under clothing
  • attractiveness
  • the price point for its intended use

Cooling vests aren’t usually covered by health insurance. Still, it never hurts to double-check with your insurance provider. Some programs may also help offset the cost, such as the Multiple Sclerosis Association of America (MSAA) and the Multiple Sclerosis Foundation. Military veterans may also qualify for a free Polar Products cooling vest through the United States Department of Veterans Affairs (VA).

The most important thing is to listen to your body and to know your limitations. MS and its symptoms can be successfully managed.

It also doesn’t hurt to be aware of techniques that can help you stay cool without your vest.
