I'm in the middle of the fence on this one.  Purchased it to help compress and possible loose some weight through sweat/water loss.  The vest runs a bit small and is thicker than I had thought initially.  It's a bit bulky to wear under anything and it does ride up and need adjusted constantly.  It is very strong neoprene material and compresses as I had hoped, yet the thickness and movement makes it difficult to wear indiscreetly.  For these reasons it hangs in my closet, for the most part unused.  I'm not sure if there's one out there that doesn't have these characteristics, however I thought I'd just throw this out there.  Good luck!  NOTE:  If you appreciated this review please give it a thumbs up/like your helping me to continue to give honest/unbiased insight into products Ive used and you may have questions about.  Interested in a product but don't know enough about it and would like it reviewed?  Please let me know and I'll see what I can do... Thank you
