Questions? We’ve Got You Covered
Who is AlphaCore designed for?
Any man who wants his shirts to sit better and his silhouette to look sharper the moment he gets dressed. It works under a t-shirt, a dress shirt or a suit
How does the AlphaCore tank work?
Targeted compression zones are knitted into the fabric: firmer across the midsection and chest, lighter across the shoulders. The result is a smoother line under clothing while you wear it.
Is this a medical or therapeutic product?
No. AlphaCore is a garment, not a medical device or a posture brace, and it isn't intended to treat, prevent or relieve any condition. It doesn't cause weight loss — the shaping effect is visual and lasts while the vest is worn. If you have a back, chest or circulation concern, see your doctor
Is it visible under a shirt?
It's designed not to be: flat seams and a no-roll hem mean no ridges showing through. Under a standard t-shirt or dress shirt it stays out of sight. Under very sheer or very tight fabrics, the neckline may show — same as any undershirt.
Can I machine wash it?
Yes. Cold gentle cycle, no fabric softener, lay flat to dry.
