CB14 and CB15 are made from the same high-stretch fabric as the CORE collection, but unlike the CORE binders, they do not have a cotton liner. Instead, we added a stretchy, breathable mesh layer to the front panel for enhanced comfort during everyday wear. They are a great option if you have sensitive skin. Similar to other binders from the FLOW line, these models free you from the 8-hour wear limit, allowing for extended use. • Compression Level: High • Sensory friendly • They liberate you from the constraints of an 8-hour usage cap, enabling you to wear them for prolonged periods (10-12 hours). However, please avoid wearing them while sleeping. • The front panel is made of two layers of high-stretch nylon with a breathable, elastic mesh in between. This design provides compression while allowing for effective airflow, keeping you cool and wicking away sweat. • Breathable and sweat-wicking high-stretch nylon fabric. • Main: 75% Nylon, 25% Lycra; Mesh: 80% Nylon, 20% Lycra
