Great Product

I purchased the slimming Titan undershirt. When I received it the left seam was torn. Contacted customer service and was asked to send a picture of the seam. I did and was told they would send a new one asap. I received it within 2 days!! Love the shirt and customer service is excellent. I will be buying more. I would recommend this product.

Confidence Booster

I love these undershirts. I Initially had the XL and it gave me a big confidence boost whilst I was at the early stages of losing weight. They're very comfortable and not restrictive at all. I've lost enough weight to drop down to the L size and it's just as good.
