Product Details

Our patent pending TempSync T-Shirt Bra is the world's first thermoregulating bra. Better than a breathable T-Shirt bra, the innovative 37.5® Tech fabric is infused with natural minerals to actively balance body temperature before you get hot. This is the best cooling bra for menopausal hot flashes and begins working before you ever start to sweat. Includes everything you need in an everyday T-shirt bra: foam cups for shape, flexible wire for support, adjustability for a perfect fit, and no annoying tags.

  • The first-ever intimates collection featuring 37.5® Tech, engineered to fight hot flashes.
  • Breathable, perforated cups for shape
  • Wear 2 ways — adjustable straps change to x-back
  • Adjustable back closure
  • Flexible, poke-free underwire
  • Scratch-free tagless label

Bra Size Calculator & Chart

Thirdlove offers over 60 bra sizes from 32 to 44 band and bra cup sizes from AA to H cup, including our exclusive half cup sizes. Using your current bra size as a starting point, you can refer to the bra cup size chart below to refine your fit.

Bra Size Calculator & Chart

How To Use The Bra Size Chart

When using the chart to find your bra size, keep in mind:

  • The band size increases as you move from left to right. Move left or right within the row if your band doesn't fit.
  • The cup size increases as you move from top to bottom on the chart. Move up or down the columns if your cups don't fit. In between cup sizes? Go up or down a half-cup! And keep in mind if you want styles that are full coverage or not!
  • Bra sizes that share a row are sister sizes, meaning they share the same cup volume (though they have different cup letters). For example, at a glance they’re all just different bra sizes. However, the row with bra sizes 36C, 38B, and 40A have something in common: they all have the same cup volume but have different band sizes. The same goes for the row with bra sizes 38H, 40G, 42F, 44E, 46D, and 48C.
Bra Size Calculator & Chart

Measure snugly around your rib cage (underbust) and around the fullest part of your bust, in inches. Step 1 gives your band. For step 2, subtract your underbust from your bust and find the difference in your band's column. These are the sizes our Bra Size Calculator gives.

Step 1: Band size by underbust measurement (inches). Each range excludes its lower value and includes its upper value.
Underbust (in) Band size
24.9 – 28.5 30
28.5 – 30.5 32
30.5 – 32.5 34

34.5 – 36.5 38
36.5 – 38.5 40
38.5 – 40.5 42
40.5 – 42.5 44
Step 2: Bra size by band and by bust minus underbust (inches). Each range excludes its lower value and includes its upper value.

The calculator only gives a size for an underbust over 24.9 in, up to 42.5 in, with a difference of up to 13 in. Blank cells and measurements outside these ranges have no size in the calculator.

    Stays cool and super comfortable

    Very happy with this bra. The first one I got was a little off on size for me but the return process was easy and the next one I got was a perfect fit. I sometimes have to work outside for my job and this is great for keeping cool, comfortable and keeping down sweat. Definitely buying another!

    This is a very comfortable

    This is a very comfortable and breathable bra. It deals with heat well, though I may prefer another bra for very high heat and humidity weather. I find this more supportive than the other TempSync bras and only wish it was wireless. I might take out the wire to try it--just a personal preference-- as this bra is actually the most comfortable wired bra I've ever tried.

    New go to bra

    A very comfortable bra! I like that it does not have the ruffled strap like the classic Tshirt bra I have gotten in the past. It is a little more likely to pill though if your drawer is not deep enough. Other than that that,
    Amazing bra. My go to.

    Wanted to love it

    The fabric is nice and soft. The fit, not so much. The bands in the side would not lay flat and initial wear, the cup was fine but as the day went in, the space in the cup widened as though the material stretched or my boobs shrunk.

    Perfection

    38DD. I love this bra so much. I live in Texas (near Dallas) and this saved me this summer. It is much more breathable than your average bra. I love that you get thin straps that are easy to hide in a tank top but still get the 3 hook band. Also, the quality of third love really is worth the money. I’ve been wearing their bras for 8 years. I haven’t even had to buy many of them because they last so long. Like literal years of wear.
