Comfort
Both my fellow tester and I thought this bra was very comfortable. The stretchy polyester/elastane fabric didn’t chafe or rub, even on long runs. Another plus: although this is a racerback style, the straps didn’t dig into my neck.

Fit/Mobility
One tester wore the TechFit Bra x-country skiing, running, and to yoga, and reported favorably in this category. I thought this bra moved well with the body, even for dynamic activities like yoga. The downside to fit is that the bra only comes in S/M/L sizing (pretty typical for a sports bra) so there is no customization.

Functionality
This style is customary for sports bras: over-the-head racer back. No bells or whistles, and no adjustability.

Support
The Techfit has average support. Although this bra (or any other for that matter) would be fine for A/B cups, our C cup tester reported that the Techfit provided her only minimal support. As a B cup myself, I found the compression style fine for road running and mellow trails.

Breathability
This is a full-coverage bra (read: lots of material) so the mesh back was a welcome detail when it got steamy.

Value
At a mere $25, this bra is certainly a great value for B cups, but C cups may have better results putting their money elsewhere.
