MOUNT HOREB, Wis., Aug. 05, 2026 (GLOBE NEWSWIRE) -- Duluth Trading Co., a leading brand in functional workwear and outdoor apparel, today highlighted its latest collection of cooling clothing, UPF apparel and moisture-managing gear designed to help people stay comfortable through extreme heat, humidity and unpredictable weather. Built for work, travel and everyday life, the collections combine cooling technologies, quick-drying fabrics and sun protection to perform across hot, humid, rainy and dry conditions.
As another summer of record-breaking temperatures grips much of the United States, consumers are increasingly searching for practical answers to questions like "What should I wear in 100-degree weather?", "What clothes keep you cool?" and "Does cooling clothing really work?"
According to National Oceanic and Atmospheric Administration (NOAA), the first six months of 2026 ranked as the third-hottest January-through-June period in the 177-year global climate record, while long-range forecasts from The Old Farmer’s Almanac called for hotter-than-normal conditions across much of the country through August. The result has been prolonged heat waves, high humidity, sudden downpours and stretches of triple-digit temperatures driving increased interest in clothing engineered to manage sweat, dry quickly and provide built-in sun protection.
“Summer weather isn't one-size-fits-all anymore," said Ricker Schlecht, Senior Vice President of Product Development at Duluth Trading. "The people who wear Duluth are getting things done in all kinds of conditions, from job sites and gardens to trails and travel days. We design apparel around real-world use, creating gear that helps people stay comfortable and focused on what they need to accomplish, whatever the forecast brings.”
What Should You Wear in Hot Weather?
Choosing clothing for extreme summer temperatures starts with performance fabrics rather than simply lighter garments. Whether you're working through humid mornings, afternoon thunderstorms or dry heat, apparel should include:
- Moisture-wicking fabrics that help pull sweat away from skin
- Fast-drying materials that stay comfortable after heavy sweating or summer rain
- Lightweight construction that promotes airflow
- UPF-rated fabric to help protect covered skin from ultraviolet rays
- Cooling technologies that reduce heat buildup
- Stretch fabrics that maintain comfort while moving throughout the day
