OBGYNs recommend natural intimates
Sarah Yamaguchi
MD, FACOG, Board Certified Gynecologist at DTLA Gynecology
I recommend that all of my patients wear all-cotton underwear, because it breathes better.
Suzy Lipinski
M.D., Board-Certified OBGYN
The best fabrics are natural—cotton, hemp, bamboo, and linen. These allow the skin to breathe, unlike synthetics such as nylon and satin, which should be avoided.
Jamie Ivkov
bsn, rn | functional health & nursing
After my own breast implant illness and total capsulectomy, I learned the importance of natural fabrics. Net Positive is my top choice for all-natural intimates!
Anjali Malik
MD, Breast radiologist
Natural fibers support personal and planetary health by reducing chemicals and hormone disruptors, improving vaginal, reproductive, and urinary wellness.
Catherine Ebeling
MSN-PH, BSB, RN
Synthetic fabrics shed plastics we absorb through skin and mucous membranes. Choosing natural fibers, especially for underwear, helps protect sensitive areas.
Morgan Ragland
RN, Fertility, Prenatal Coach
As a Fertility Health coach, RN, and mom of four, I choose Net Positive’s natural fabrics—free from chemicals and microplastics that disrupt hormones and fertility.
Beth Arnold
MD, FACOG, Board Certified Gynecologist at DTLA Gynecology
Some fabrics heal, others hide toxins. As a wellness RN & pregnancy coach, I help women lower toxic burden and boost fertility with natural fabrics.
