The 10 Best Cooling Vests for Multiple Sclerosis (MS)

Even a minor rise in temperature — as little as 0.5°F (0.75°C) — can temporarily intensify symptoms and even trigger an exacerbation. Symptoms may also flare because of:

• exercise or an overly active routine
• hot showers or baths
• fever from a cold or other short-term illness

Clinically, this is called Uhthoff’s phenomenon. In fact, overheating was once used as part of diagnosing MS before magnetic resonance imaging (MRI) became common. Because a small temperature rise can hamper nerve conduction enough to cause symptoms, clinicians historically used a “hot tub test” to provoke them.

Although the effects are temporary, modest increases in temperature can significantly diminish quality of life.

How we chose

Cooling vests help stabilize core temperature, prevent swings in body heat, and reduce heat-triggered flares.

There are several types of cooling vests at various price levels and with different features. Battery- or electric-powered models (active cooling vests) can be pricier but offer extended cooling. Gel-pack or passive vests typically don’t cool as long but tend to cost less. For this roundup, we focused on gel pack and passive cooling vests and included cooling accessories useful for MS, such as neck and wrist wraps. Selections were based on customer feedback, price, and product features.

Comparing cooling vests and accessories

Choosing a vest

No matter which vest you consider, ensure it fits snugly around your torso. A vest that’s too loose may not deliver the cooling effect you need.

Other factors to weigh include:

• how long it keeps you cool
• what’s required to recharge or re-cool it
• its weight
• care and washing instructions
• whether it’s meant for passive or active use
• if it can be worn under or over clothing
• appearance
• the price relative to intended use

Beat the heat

• Choose lightweight, breathable fabrics.
• Use air conditioning or set up fans for a cross breeze.
• Drink chilled beverages and keep ice pops on hand.
• Take cool showers or baths to relax and cool off.
• Spend time outdoors during the coolest parts of the day.

Frequently asked questions

Why do people with MS need a cooling vest?

Heat sensitivity is common among people with MS. Cooling vests lower core body temperature, which can reduce heat-induced symptom flares.

How effective are cooling vests?

High-quality cooling vests are effective at lowering core temperature and cooling the body. Their effectiveness can depend on factors like body mass index, ambient temperature, and what you’re wearing. You may need to try a few options to find the best fit for you.

Are cooling vests safe?

For most people, cooling vests are safe. Check with your healthcare provider to confirm they’re appropriate for your situation.

Are cooling vests covered by insurance?

Most insurers don’t pay for cooling vests, though exceptions exist. Some plans may cover them for diagnoses such as MS. Contact your insurer to see if they will cover a vest.

How long does a cooling vest last?

Cooling durations vary by product and individual factors. Expect cooling times roughly between 1 and 4 hours on average.

Takeaway

Cooling vests are typically not covered by health insurance, but it’s worth checking with your provider. If you have a flexible spending account (FSA), verify whether it covers a cooling vest or accessories. Some organizations may help offset costs, such as the Multiple Sclerosis Association of America (MSAA) and the Multiple Sclerosis Foundation. Veterans may be eligible for a complimentary Polar Products cooling vest via the U.S. Department of Veterans Affairs (VA).

The key is to pay attention to your body and know your limits. With proper strategies, MS symptoms can be managed effectively.

It also helps to be familiar with other techniques to stay cool when you’re not wearing a vest.
