Sometimes, the strongest statement is the simplest one. The Basic Black Helnium Arm Sleeve is designed as the essential counterpart to every Crystal Arm Sleeve. Its minimalist silhouette allows the scientific artwork on the opposite arm to remain the focal point, creating the distinctive asymmetrical identity that defines Helnium. Clean, technical and timeless, it pairs effortlessly with every design in the collection while maintaining a refined performance aesthetic. Whether you're running, training, playing volleyball or tennis, cycling or simply wearing it every day, this sleeve delivers understated elegance with technical performance.
Premium minimalist design
Lightweight compression fabric
Breathable and moisture-wicking
Comfortable stretch fit
75% High Quality Polyester + 25% Spandex
Handcrafted in Italy
Made to order
Every Helnium arm sleeve is sold individually. Rather than wearing two identical sleeves, Helnium was designed around a simple idea: one arm becomes the artwork, the other creates the balance. Pair your Basic Black Helnium Arm Sleeve with any Crystal Arm Sleeve to create the complete Helnium silhouette. This asymmetrical approach has become the signature of the collection, clean, unique and immediately recognizable.
Each purchase includes one (1) arm sleeve only, not a pair. To recreate the complete Helnium look shown in our visuals, combine one Basic Black Helnium Arm Sleeve with one Crystal Arm Sleeve of your choice.
