Slower to dry than traditional polyester/lycra blends
For smaller cup sizes, this is a fabulously versatile bra that is comfortable enough for yoga and supportive enough for running. If you’re not an A cup, however, you may find this bra is not supportive enough for high impact activities. It is ideal, though, for cold weather activities like snowshoeing or skiing.
Comfort The PhD bras were the first wool bras I’ve ever worn. I was a little skeptical at first (I thought it might be itchy), but the merino blend is actually extremely cozy. The seamless construction is also noteworthy.
Fit/Mobility This is a great bra for activities that demand high mobility, like yoga or Nordic skiing, due to the super close fitting, supple fabric. Sizing is standard XS-XL with no adjustability options, so my size M was a little too snug, even with the flexible material.
Functionality This is a standard over-the-head, tug-it on style bra, with no bells or whistles.
Support As a 34B, I didn’t find this bra to be supportive enough for high impact activities like stair workouts, running or jumping. Although it is built like a traditional compression bra, the fabric allows too much “give” to be truly supportive. It’s ideal for medium or impact activities that require a lot of movement.
Breathability Merino is naturally absorbent, but because it is full coverage with no mesh, I did feel sticky after long workouts. Because merino is my top choice for warm-when-wet insulation, though, I thought this bra’s niche was cold weather sports such as skiing or snowshoeing.
Value This was the most expensive out of the 20 bras we tested at $70. Although it is high on the versatility scale, it lacked the necessary support to give it a high score here.
