Two bikini briefs, two very different fabrics
The CX01MD Modal Brief and the CX16N Supplex Bikini Brief share a similar low-cut shape, but they are built from different materials with distinct strengths. The CX01MD uses a 96% Modal / 4% Lycra blend that feels silky and ultralight, while the CX16N uses a 92% Supplex / 8% Lycra blend that mimics cotton with advanced fibre performance. Your choice comes down to whether you prioritize a soft, barely-there feel or a more structured, cotton-like hand with a wider waistband.
Both briefs include the Cocksox enhancing pouch and unlined construction, so the main differences are fabric behavior, waistband design, and available colors and sizes. Neither is inherently better—each suits a different preference and routine.
Fabric feel and moisture handling
- CX01MD Modal Brief: Modal is a natural and sustainable fabric derived from beech tree pulp. It feels silky soft against the skin, wicks moisture away from the body, and is described as ultralight—like wearing nothing at all. It is fully breathable and dries faster than cotton.
- CX16N Supplex Bikini Brief: Supplex offers the feel of cotton with the benefits of advanced fibre technology. It draws moisture from the body, is fully breathable, and holds its shape after many washings. It also provides long-lasting softness and durability.
Cut, coverage, and waistband
- CX01MD Modal Brief: The CX01 cut is the original Cocksox design—a skimpy high-cut brief with the Original Pouch. It has an internal elastic waistband for extra comfort and support, and a flattering, unlined cut for maximum style.
- CX16N Supplex Bikini Brief: This bikini brief keeps you covered out front and back, but the sides are open. It features a 32mm waistband with the Cocksox logo and a soft feel. The pouch keeps your goods in place, and the waistband wraps right around to keep the briefs on.
Sizing and color availability
The CX01MD Modal Brief comes in sizes S, M, L, and XL, but color availability varies by size: Arctic Blue is offered in all four sizes, while Moss and Maple are only listed in XL. The CX16N Supplex Bikini Brief comes in sizes S, M, L, and XL across three colors: Schwarz, Monaco, and Capri. If you want a specific color in the CX01MD, check which sizes are in stock before ordering.
Key catalog facts for each brief

CX01MD Modal Brief - CX16N Supplex Bikini Brief: Composition: 92% Supplex, 8% Lycra; fabric offers the feel of cotton with advanced fibre technology and faster drying than cotton. Gives a cotton-like hand with performance benefits, useful if you prefer a more traditional fabric feel.
CX16N Supplex Bikini Brief
Care that keeps either fabric in shape
Both briefs carry pad-print care labels (no scratchy tags) and share the same recommended care: turn the garment inside out or place it in a wash bag before laundering to avoid friction with abrasive surfaces. Use a gentle cycle or hand wash in cold to warm water with a mild liquid detergent, ideally eco-friendly. Line dry in the shade to maintain fabric integrity. These steps apply equally to Modal and Supplex, so neither fabric demands a special routine beyond gentle handling.
Which brief fits your routine
Choose the CX01MD Modal Brief if you want an ultralight, silky-soft feel for everyday wear, prefer a high-cut skimpy cut with an internal elastic waistband, and value the natural, sustainable fabric story. Choose the CX16N Supplex Bikini Brief if you prefer a cotton-like feel with a wider 32mm logo waistband, open sides, and a fabric that holds its shape well after repeated washing. Both offer the Cocksox enhancing pouch and unlined comfort, so your decision rests on fabric hand, waistband style, and the colors and sizes available in your preferred option.
