What our customers are saying

Zach Sanders
Wrestling Coach - University of Minnesota - 4X NCAA All-American

"With a family full of chiropractors and being a high level Olympic hopeful wrestler I have always had an interest in health and wellness, especially if I feel it can give me an edge over my competition. I became interested in Lambs underwear as a way to protect myself from modern environmental factors such as EMFs."

Ryan Smith
MMSc - Professional Coach - Walton, KY

"As someone with 30 years in the health & wellness industry, I originally chose Lambs for the protection from EMF and cell phone radiation. Once I started wearing Lambs, it became my daily wear, not just for the protection, but because of the comfort whether I am working out or wearing a suit and tie."

Jesse Chappus
Podcaster - Windsor, Ontario - ultimatehealthpodcast.com

“I try and minimize my exposure to EMFs whenever possible but in today’s modern world that only takes me so far. It’s nice to know I have a layer of protection when wearing my Lambs underwear! Helping safeguard my privates is a no-brainer.”

Adrien Lancelot
Key Account Manager - Paris - France

"I've been using Lambs underwear for almost two years. I wear them every day and I can keep my phone in my pocket knowing that I am protected. They are really comfy and feel even softer than my previous regular underwear."
