Outdoor Research Helium Bivy - The Helium Bivy is the lightest bivy that Outdoor Research makes. Made from the same material as their ultralight rain shell, the Helium II Jacket, this bivy weighs in at a feather light 18 ounces! It features a classic, no-nonsense clamshell design and is completely waterproof and breathable. The single shock-corded overhead Delrin pole gives you breathing room at the head while the removable no-see-um netting at opening keeps those peasky biting bugs at bay. Designed to fit thicker sleeping bags, the Helium also offers high volume in the feet area. The Outdoor Research Helium Bivy is your true minimalist bivy for fast and light solo expeditions.
Outdoor Research Camp & Hike Helium Bivy 2428280008222. Weighing in at a feathery 18 ounces and featuring a classic clamshell design and durable 70D nylon floor this storm-proof shelter is ready for season after season of adventuring.
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
Tipping the scales at a feathery 18 ounces, the Outdoor Research Helium Bivy is ideal for moving fast through alpine terrain and wilderness expanses without excess weight slowing you down. However, don't let its minimalist design fool you into thinking it's lacking weatherproof performance or functional features. The Helium Bivy offers total waterproofing and maximum breathability with its Pertex Shield+ 2. 5-layer membrane, TPU floor lamination, and fully taped construction. Ultimately, this means you'll stay pleasantly dry when you're camping out in widely variable conditions, all without soaking in a sauna of built-up perspiration during humid summer months. The Helium features a clamshell design that promotes a restful night's sleep with a Delrin Single-Pole system acting as a stabilizing structure for the bivy itself. The hood unzips during pleasant weather for extra ventilation and impressive stargazing potential. No-See-Um mesh lining keeps biting insects from eating you alive when you're sleeping with the hood unzipped. Other key features include dedicated straps for attaching your sleeping pad, an internal mesh pocket, and stake-down points for securing this bivy in nasty weather.
