Description

The Black Diamond PROJECT MUSCLE TANK is the essential tank top for female climbers and sportswomen looking for a garment that is simple, robust and comfortable.

Designed in a heavyweight organic cotton (220 g/m²), it offers an exceptionally durable feel while remaining very comfortable against the skin on hot days. Its sleeveless muscle cut and slightly short design allow natural ventilation and total ease of movement, ideal for a series of technical moves on boulders or crags.

Beyond its minimalist style, this tank top relies on eco-responsible design thanks to the use of certified organic cotton, reducing environmental impact without sacrificing performance. The addition of a touch of elastane provides the necessary elasticity so that the garment follows your rotations and extensions without ever getting in your way.

Whether it’s for an intense session at the gym or chilling out afterwards, the Project Muscle Tank combines casual and technical with Black Diamond’s signature efficiency.
