Quick answer
The B.O.A Constrictor 2.0 full tight delivers consistent compression for muscle support and warmth, but getting the right size is key to comfort and performance.
Why fit matters more for compression tights
Compression tights like the Constrictor 2.0 are designed to fit snugly without restricting movement. A size too large reduces muscle support and can cause bunching. A size too small may feel restrictive and uncomfortable during longer runs. The goal is a close, even fit that stays in place without digging in.
Key features that affect fit and use
The Constrictor 2.0 includes a back zipper pocket and side drop-in pockets. These are useful for carrying a phone, key, or gel, but the pocket placement means the tights should fit securely around the waist and hips to prevent sagging. The compression fabric also helps reduce chafing, but only if the fit is correct—loose areas can rub.
How to choose the right size and use
- Measure your waist and hips: Use a soft tape measure around your natural waist (just above the belly button) and the widest part of your hips. Compare to the size chart on the product page. The Constrictor 2.0 is sized by waist and hip measurements, not by pant size. Write down your measurements before ordering—don't guess based on your usual pant size.
- Check the inseam length: The full tight extends to the ankle. If you are between sizes, consider your height and inseam. Taller runners may prefer a size up for a slightly longer leg, but the waist fit is more important. If your waist measurement falls between sizes and you are tall, size up for extra length.
- Test the fit before a long run: Wear the tights for a short jog or around the house first. The compression should feel supportive but not painful. If the waistband rolls down or the fabric feels too tight behind the knee, try a different size. A proper fit should stay in place without constant adjustment.
- Use the pockets for essentials only: The back zipper pocket is best for a key or card. The side drop-in pockets can hold a phone or gel, but avoid overstuffing them—this can cause the tights to sag or chafe. Keep pocket contents minimal to maintain the compression fit.
