1. Nudy Patooty Undershirt ($55)
"Say farewell to sweat stains" — and to endless dry-cleaner runs — by adding this "supremely soft" bamboo undershirt to your wardrobe, says Grace Elkus at Real Simple. The special dual-dry fabric in the underarm wicks away sweat. Buy it at NudyPatooty.com.
2. Mission Instant Cooling Towel ($9.99)
Soak this towel in water, wring it out, and the performance fabric cools to 30 degrees below the average body temperature. After a workout, using the towel is "like draping a bag of ice around your shoulders," says Meaghen Brown at Outside magazine. Buy it at Amazon.
3. Milk Makeup Cooling Water ($24)
Infused with caffeine and cool to the touch, this gel stick provides instant hydration to the skin, "chilling it along the way," says Zoe Ruffner at Vogue. Use it in the morning to reduce puffiness or at night for a touch of glow. Buy it at Sephora.
4. Hammacher Schlemmer Cooling Cap ($30)
One of the military's go-to sources for desert wear developed the fabric in this hat. Soak the cap in water for two minutes, and the liner will stay cool and damp for hours. Buy it at Hammacher Schlemmer.
5. Inverse Hair Conditioning System ($299)
"Take cold conditioning to a new level" with this new beauty aid, says Lyndsay Green at InStyle. After you shower, gently pull it through your tresses. Its ice-cold inserts, fresh from your freezer, will lock in moisture and boost shine. Buy it at InverseHair.com.
