Questions? We’ve Got You.
How does it fit?
This is a fitted, athletic-cut suit. Compare your measurements to the size chart before ordering. If you’re between sizes or want room to move, we recommend sizing up.
How does the heat-retaining design work?
The sauna-style fabric is designed to hold in body heat, so you warm up faster and work up a sweat from the start of your workout. It’s a warm-up layer to wear during exercise, not a replacement for it.
How do I use it safely?
Start with shorter sessions, drink plenty of water before, during, and after, and stop right away if you feel dizzy, lightheaded, or overheated. Skip it in hot or humid conditions. If you’re pregnant, have a heart condition, or have been advised to avoid heat, check with your doctor first.
How should I care for it?
Wash cold on a gentle cycle or hand wash, and hang dry. Don’t tumble dry, iron, or use bleach or fabric softener, which can damage the fabric.
How long does shipping take?
Orders typically arrive within 10 to 20 days. Your estimated delivery window is shown on the product page before you check out.
What if it doesn’t work for me?
