Cooling Vests for Multiple Sclerosis — Arctic Heat USA
Arctic Heat cooling vests are used by thousands of people living with Multiple Sclerosis across the United States. If heat makes your MS symptoms worse, a lightweight cooling vest worn during daily activity, travel, or time outdoors can make a significant difference to your comfort and quality of life.
Why Heat Affects People with MS
Most people with MS experience a temporary worsening of symptoms when their body temperature rises — a phenomenon known as Uhthoff's phenomenon. Even a small increase of less than 1°F in core body temperature can cause increased fatigue, blurred vision, weakness, and cognitive fog in people with MS.
This means that summer heat, hot showers, exercise, and warm indoor environments can all trigger symptom flares — effectively confining many MS patients indoors during warmer months.
Cooling the body before and during heat exposure is one of the most widely recommended strategies for managing MS heat sensitivity.
How the Arctic Heat Cooling Vest Helps
The Arctic Heat vest works by placing chilled gel panels directly against the skin across the chest and upper back. This draws heat away from the body and helps stabilise core body temperature — reducing the temperature spike that triggers MS symptoms.
Unlike heavy phase-change vests that use dense ice packs weighing 5–9 pounds, the Arctic Heat vest weighs just 2.2 pounds and contains no bulky inserts. The entire vest is the cooling element — a non-toxic, biodegradable viscose gel is woven throughout the garment itself. You freeze the whole vest, put it on, and it cools you immediately.
This makes it practical for daily MS life in a way that heavier alternatives often are not — light enough to wear under clothing, low-profile enough to wear at work or while travelling, and simple enough to use without assistance.
What MS Patients Say About Arctic Heat
Arctic Heat cooling vests have been used by MS patients and MS organisations across 30 countries since 2003. The vest is trusted by the MS Society of Australia and has been used across six Olympic Games — a measure of the same lightweight, performance-grade cooling technology available to every Arctic Heat customer.
Who Is the Arctic Heat Vest Suitable For?
The vest suits MS patients who experience heat sensitivity during:
- Everyday outdoor activity in warm weather
- Exercise, walking, or physical therapy
- Travel — particularly in warm climates or without air conditioning
- Work in warm indoor or outdoor environments
- Social events and occasions where staying cooler means staying longer
It is suitable for men and women, available in sizes Extra Small to 5XL, and comes in blue or white.
How to Use It for MS Heat Management
For best results with MS heat sensitivity, pre-cool your body before going into a warm environment rather than waiting until you feel overheated.
Freeze the vest the night before or at least one hour before you need it. Put it on 15–20 minutes before going outside or into a warm space. Wear it directly against your skin or under a single light layer. The vest will stay noticeably cool for up to 2 hours depending on ambient temperature.
The vest can also be refrigerated rather than frozen for a gentler cooling effect — some MS patients find this more comfortable for extended wear.
Frequently Asked Questions — MS and Cooling Vests
Will a cooling vest actually reduce my MS symptoms?
Many MS patients report meaningful reduction in heat-triggered symptoms when wearing a cooling vest. Keeping core body temperature stable reduces the temperature increase that triggers Uhthoff's phenomenon. Arctic Heat recommends speaking with your neurologist or healthcare provider about incorporating cooling therapy into your MS management plan.
How is Arctic Heat different from other cooling vests for MS?
Most cooling vests use separate ice packs or phase-change material inserts that add significant weight and bulk — typically 5 to 9 pounds. The Arctic Heat vest weighs 2.2 pounds because the entire garment is the cooling element. There are no packs to freeze separately, no inserts to position, and no bulk under clothing. It is the most wearable everyday option for MS heat management available.
Can I wear it under my clothes?
Yes. The low-profile design is specifically suited to wearing under a shirt, blouse, or light jacket. Most users cannot tell you are wearing it.
How long does it stay cool?
Up to 2 hours in typical conditions. You can carry a small cooler bag with the vest inside to re-chill it during longer outings, or keep a second vest frozen at your destination.
Is it easy to use independently?
Yes. Put it on like a regular vest. No zips to manage, no packs to insert. It is designed to be simple enough to use without assistance.
Does insurance cover cooling vests for MS?
Some US health insurance plans and MS Society programmes provide assistance for cooling products. We recommend contacting your insurer and the National MS Society (nationalmssociety.org) for current coverage information. Arctic Heat USA can provide an invoice for insurance submission purposes on request.
