The new COREEX Winter Compression Tights combine deep-warming ThermoFleece™ with medically inspired compression zones that noticeably relieve your legs throughout the day. They keep you warm from 50°F down to 14°F without overheating, and stay perfectly in place thanks to the anti-slip waistband. The 3D shaping structure naturally sculpts your stomach, glutes, and legs, while the ultra-opaque material makes any outfit look elegant. Ideal for the office, everyday wear, and winter walks — for anyone who wants warmth and comfort without compromise.
Model's height: 5'5"
Model wears: M
Material: 72% polyamide, 28% elastane. Four-way stretch knit with graduated compression zones and a bonded, non-roll high waistband. Breathable and opaque enough to wear on its own.
Care: Machine wash cold on a gentle cycle with like colors. Do not bleach, do not iron, do not tumble dry. Air dry flat to protect the compression fibers. Skip the fabric softener — it coats the elastane and shortens the life of the compression.
Shipping: Free standard shipping on every U.S. order. Orders placed before 2pm ET ship the same business day, and delivery usually takes 5-7 business days. The leggings will be produced especially new for every order. You'll get a tracking link by email as soon as your parcel leaves the warehouse.
Returns: 30 days from delivery. Items need to be unworn, unwashed and in their original packaging with the tags attached. Size exchanges are free — email help@trycoreex.ch with your order number and we'll take it from there.

No. COREEX is a registered business with a real support team behind it. Every order is confirmed by email, ships with tracking, and is covered by our returns policy and money-back guarantee. The reviews on our site come from verified buyers only.
Most customers say their legs feel lighter and less tired from the very first wears. Changes in how the skin looks build up more gradually with regular use, and how quickly that happens differs from person to person.
Our leggings use graduated compression: firmest at the ankle and gradually easing toward the waist. It is supportive enough to feel noticeable all day, without being so tight that it becomes uncomfortable during normal wear.
Measure your waist and hips and compare them with the size chart on the product page. If you fall between two sizes, choose the larger one for all-day comfort or the smaller one if you prefer a firmer, more sculpting fit.
Yes. The knit is engineered to stretch and recover across a wide range of body shapes, and the high waistband is shaped to stay put rather than roll down. Check the size chart for the range that matches your measurements.
Graduated compression applies gentle, structured pressure along the leg, which supports circulation and lymph flow. That is what most wearers describe as their legs feeling lighter and less heavy at the end of a long day.
Each product page covers materials, fit and care, and you can read more about how the leggings are made further up this page. If something is still unclear, our support team is happy to help — just get in touch.
