Thirdlove, the female-founded lifestyle brand known for its inclusive sizing and signature half-cup bras, announced the launch of TempSync, a temperature-regulating bra and underwear collection designed to support women through perimenopause and menopause. The line introduces three essential styles—TempSync T-Shirt Bra, TempSync Wireless Bra, and TempSync Hipster—bringing functional innovation to the lingerie drawer.
“So many women silently deal with temperature swings, night sweats and hot flashes—and most lingerie is not made with that in mind,” said Heidi Zak, co-founder and CEO of Thirdlove. “We designed this collection to meet a real need and help women stay cool, dry and confident—especially during times when their bodies are changing.”
At the heart of the collection is 37.5 Technology, a fabric long used in men’s performance apparel and now applied to women’s intimates for the first time. Infused with natural minerals, it actively balances body temperature to help maintain an optimal core temperature. Lightweight foam and perforated detailing further enhance airflow, delivering next-level comfort through hot flashes, hormonal changes and everyday temperature shifts.
To help break the stigma around menopause, Thirdlove partnered with actress and advocate Jennie Garth, who has spoken openly about her own menopause journey. Together, they aim to encourage open conversations and bring visibility to a life stage too often overlooked.
“I’ve shared my personal experiences with my menopause journey because it’s time we talk about it more openly. We deserve this moment!” said Garth. “Thirdlove’s new TempSync collection has genuinely made a difference for me. This unique fabric works with your body temperature, making hot flashes much more manageable. These intimates are a meaningful step toward normalizing menopause, something we will all go through, and ensuring all women feel seen, supported and confident.”
Available in three classic colorways—black, taupe and air—prices for each style range from $20 to $78. The collection is available for purchase at thirdlove.com and includes:
- TempSync T-Shirt Bra: The high-performance twist on Thirdlove’s 24/7 Classic T-Shirt Bra features lightweight perforated foam cups for shaping, coverage and breathability.
- TempSync Wireless Bra: This wire-free essential has a barely-there feel, adjustable 2-in-1 straps, and a tagless back closure for friction-free comfort.
- TempSync Hipster: This ultra-soft cooling underwear adapts to your body’s temperature to keep skin dry and irritation-free throughout the day.
