Care
Machine wash cold on a gentle cycle. No bleach, no fabric softener — both break down the elastic fibres. Do not tumble dry; hang to dry to keep the compression.
FAQ
How tight should it feel?
Firm all over, with the strongest hold around the stomach and waist. It should never pinch, restrict your breathing or leave marks. If it does, go up a size.
Can I wear it all day?
Yes. The knit breathes and wicks moisture, so it works under a shirt at the office as well as under a T-shirt on the weekend.
Does it show under clothes?
No. The low crew neck and flat seams sit invisibly under a shirt, polo or T-shirt.
Which size should I choose?
Go by body weight using the Size & fit guide, not by your usual T-shirt size.
