"I'm out in the garden most mornings before the heat gets bad. This keeps me comfortable long enough to actually finish what I'm doing instead of giving up after twenty minutes."

"By the end of the day I'm usually exhausted from the heat. Wearing the PhaseCore Pro keeps me noticeably more comfortable, especially during the hottest part of the afternoon."

"I wear it on long hikes during the summer and it makes a noticeable difference. Instead of overheating after an hour, I stay comfortable and can enjoy the trail much longer."
Jason P.
“I work outside most days and wanted something that didn’t need batteries or charging. I freeze the packs the night before, slide them in before work, and that’s it. The vest feels a little heavy at first, but once the afternoon heat kicks in, I’m glad I have it on.”
