Here's what other sites are saying:

The Outdoor Research Helium Bivy is a minimalist shelter for solo adventurers. Because if it gets any bigger they'd just call it a tent. This ultralight shelter is made from Pertex Shield+ 2.5L fabric, a 100% nylon with a floor that is tougher than the Upper, for longevity and protection. The single pole creates enough space so your face isn't stuck up against the fabric and you can start catching z's with the no-see-um mesh exposed on warmer nights, watching the stars. In wetter weather, zip the whole thing up for waterproof protection throughout the night. Nobody wants their head getting rained on while they sleep. Features of the Outdoor Research Helium Bivy Waterproof Breathable Lightweight Fully Seam Taped Anti-Fungal Coating on Floor Five Stake Loops; One Guy-Line Loop High-Volume Toe-End Removable No-See-Um Netting at Opening Single Shock-Corded Overhead Delrin Pole Sized to Fit Thicker Mats Sleeping Pad Straps Small Internal Mesh Pocket
