The patented Supacore Coretech pregnancy support short uses the leading medical-grade compression to help alleviate lower back pain, pelvic girdle pain, sciatica, discomfort and pelvic instability associated with pregnancy. Stretch seamless soft flex zone adapts to the growing baby for extra comfort. Anti-chafing technology avoids painful thigh irritation, especially during warmer months. Supacore’s CORETECH™ technology uses patented body mapping engineering to copy the body’s core stability system and provide targeted compression throughout the pelvis and core. Designed by Dr Carolyn Taylor ,an expert in pelvic instability during pregnancy. During your pregnancy, it's typical for your abdomen to expand approximately 1 cm each week to accommodate your growing baby. Weight gain patterns also vary throughout the pregnancy stages: you can expect to gain up to 2 kg during the first trimester, followed by approximately 0.5 to 1 kg per week during the second and third trimesters. Overall, this amounts to a total weight gain of about 12 to 16 kg over the entire course of your pregnancy. As a result, you may find that many of your regular clothes no longer fit comfortably. Please note that the size chart is  a guide and everyone and every body is different. During pregnancy our bodies can change dramatically and some people may need 2 sizes to last their whole pregnancy.  If, during your pregnancy you feel that you need an extra pair let us know we will discount the 2nd pair.
