Superlight Series tent canopies and bivys are constructed with NanoShield—Black Diamond’s proprietary breathable single-layer fabric. NanoShield is extremely water-resistant boasting the highest water column rating of any breathable, single-layer fabric. This is thanks to our exclusive Silicone Nanocell coating, which allows the fabric to remain light, soft and packable.
