Hidden Cult Tank Top – Performance Activewear
Our signature tank top is engineered for athletes who demand performance without compromise. We built this piece with a four-way stretch jersey that moves with your body through every rep, sprint, and transition.
We source a proprietary polyester-spandex blend that balances compression with airflow. The fabric’s open-weave structure allows heat to escape while the spandex content maintains shape recovery after stretching. Independent lab testing shows our jersey wicks moisture 40% faster than standard cotton blends.
Fit & sizing guidance
This tank runs true to size with a relaxed fit through the torso and a slightly tapered waist. The armholes are cut high to prevent gaping while the racerback straps measure 1.5 inches wide for comfortable load distribution under sports bras.
We recommend sizing up if you prefer additional length or plan to layer over a long-sleeve base. The curved hem falls approximately 2 inches below the natural waistline on our fit model (5’7″, wearing size M). Customers between sizes typically find their usual choice works, though those seeking a cropped look often size down one increment.
Care instructions & durability
Machine wash cold with like colors on a gentle cycle to preserve elasticity. We advise against fabric softeners, which can coat fibers and reduce moisture-wicking performance over time. Tumble dry on low heat or hang dry to extend garment life.
The flatlock seams are double-stitched at stress points — underarms and hem — where most activewear fails first. After 50+ wash cycles in our internal testing, the fabric retained 94% of its original stretch and showed no pilling or color fade. Avoid bleach and direct ironing; the polyester blend is wrinkle-resistant and needs no pressing.

Hidden Cult tank top questions
The polyester-spandex blend resists shrinkage when washed in cold water and tumble dried on low heat. Our testing shows less than 2% dimensional change after 50 wash cycles. For best results, avoid high heat settings and remove promptly from the dryer to maintain the original fit.
The 180 GSM fabric weight provides opacity during bending and stretching movements. We tested the tank under bright studio lighting and during outdoor sessions, and the weave density prevents sheerness even when wet. Lighter colors like white and sand maintain coverage, though we recommend skin-toned undergarments for added confidence.
This tank does not include a built-in shelf bra, so we recommend pairing it with a separate sports bra for workouts. The racerback design coordinates with most bra strap configurations, and the high armholes prevent gaping while still allowing ventilation.
The racerback construction eliminates fabric across the shoulder blades, allowing unrestricted overhead pressing, pull-ups, and swimming strokes. The straps measure 1.5 inches wide to distribute weight comfortably without digging in during high-rep movements or long training sessions.
The curved hem falls approximately 2 inches below the natural waistline on our 5’7″ fit model wearing size medium. This is slightly longer than cropped styles but shorter than traditional tunic-length tanks. The side vents add an extra inch of coverage at the hips while improving airflow during movement.
The wicking technology is integrated into the fiber structure rather than applied as a coating, so performance remains consistent through repeated washings. Avoid fabric softeners, which can coat fibers and reduce moisture transfer. Our lab testing shows 96% wicking efficiency maintained after 50+ laundry cycles.
We offer free exchanges within 30 days of purchase for unworn, unwashed items with original tags attached. If you are unsure about sizing, we recommend reviewing our detailed size chart and customer fit feedback before ordering. Most customers find their usual size works well, though those preferring a cropped look often size down.
