The women’s Opedix Core-Tec 2.0 offers a scientifically engineered base layer in the form of comfortable compression shorts. 
Opedix makes several garments that are intended to promote dynamic alignment and optimal join function. Opedix uses a patented design they call Torque Reform Technology to enhance core stability. Basically by improving alignment, athletes will see reduced pain and be able to perform for longer.
This compression technology was a first for me but I decided to put it to the test. As I suited up in the pre-dawn hours for the five-mile hike up Hayden Peak I put on the form-fitting Opedix shorts as my base layer.
I was skeptical of the fit at first, as they seemed rather snug. I was worried my movement would be inhibited and I would overheat. But the four-way stretch material made them effective and versatile without being restrictive. The material is also moisture wicking and breathable so they were comfortable for the entire day, not to mention the anti-odor fabric will come in handy over time.
The shorts consist of twenty-six panels woven together, stretching from my lower abs over my quadriceps, for optimal fit and 
function. There are essentially bands sown into the fabric that spiral up across the hips, which provides improved control and neutral pelvic alignment. This design is intended to reduce co
re muscle fatigue and I was pleasantly surprised to find that my hips and lower back were much less sore than usual for a steep hike of this length.
I can see how the Core-Tec shorts provide performance improvement over time. I find that when I hike my posture suffers- I lean forward to compensate for the heavy pack and the steep incline, which fatigues my back muscles. The shorts compress my hips into alignment with my back, making me stand up straighter and my back pain becomes minimal.
