Hydrologic vests keep both workers and vacationers cool (Photo courtesy of Fieldsheer)

Whether you need to stay warmer in winter or cooler in summer, Fieldsheer has a vest for you. Under its Mobile Warming label, Fieldsheer creates clothing to keep you warm. Its Mobile Cooling label creates technical clothing designed to keep you cool. The company considers itself a technology company first, rather than a garment maker because it owns and operates the entire supply chain that creates everything from the Mobile Warming vest’s battery to its heated panels and the Bluetooth MW Connect app that controls the vest’s warmth.

By controlling the supply chain, Fieldsheer can also reduce its environmental impact. That’s why I’ve chosen to review its vests on my eco-focused website.

Over the last year, I’ve had the opportunity to test both a warming and a cooling vest, and I am impressed with the technology in both. Here are my reviews of each type of vest.

Women’s Company Vest

The Company Vest is ideal for travelers like me that don’t like to wear a lot of layers. Since I traveled less last year due to the Covid pandemic, I primarily tested the vest in Southern California and on a trip to Dallas last winter. Since Santa Monica is often chilly on evening walks at the beach near Santa Monica Pier, the Company vest is a perfect layer. Although I initially found myself primarily controlling the vest’s temperature by pressing the 7.4 volt Lithium ion battery’s button, the MW Connect app works well. And most importantly, it shows the battery level. 

In my outdoor walks and commutes, the battery lasted the entire trip, but I was often in and out of the elements, always turning off the heat to avoid burning up indoors. The 7.4 volt battery is rated to last up to 10 hours. Although I haven’t had a chance to test the vest out skiing or snowshoeing, I think carrying a spare battery is a good idea for full days out in the snow.

And beyond its technology, I love the vest’s comfort and design, especially its top zippered pocket where I can stash my I.D., keys and a credit card.

The women’s Backcountry vest retails for $179.99. The men’s Backcountry vest is also $179. Vests usually come in two or three colors. The Company vest is sold directly from Fieldsheer and also via Amazon’s Fieldsheer Apparel Technology store.

Hydrologic Cooling Vests

Over the summer and on recent hot autumn, I tested one of Fieldsheer’s unisex Mobile Cooling Hydrologic Vest. The vest is lined with a activated Hydrologic®’s Super Absorbent Polymer fabric interlining that absorbs and holds water to keep you cool all day. Before heading outside, you activate the vest’s cooling technology by soaking it in water for a couple of minutes. After wringing it out (so you don’t leave the house dripping), you put it on over your clothes. The cooling vest uses evaporative cooling to reduce our core temperature to keep us cool and comfortable even when the heat would normally be unbearable. The vest is great for travelers because it’s light weight and easy to pack.

You can also buy Mobile Cooling ice packs to freeze and drop in the vest’s pockets. I sometimes like to grab my two ice packs and head out in the vest without first soaking it in water.

The unisex cooling vest I tested is on sale for $44.99. And the Mobile Cooling ice packs are $19.99.
