The best selling Helium bivy has been updated and is now even lighter whilst still retaining its excellent features. It has a separate insect mesh 'door' and a front pole that gives the whole thing some structure and stops the fabric from laying on your face.
Outdoor Research says:
Award winning for it's ultralight prowess, made even lighter.
Our Helium Bivy used to be the best-selling, award-winning, lightest shelter offered by Outdoor Research - until we outshone it with this: The newly renovated Helium Bivy. 14% lighter than its previous version, the Helium Bivy is ideal for multiday minimalists who are looking to trade weight for speed, agility, and performance. Thru-hikers and bikepackers love the new Helium for its refined footprint and reduced weight, and trust it for its feathery waterproof and breathable Pertex® Shield+ fabric that doesn't compromise on durability. A no-nonsense clamshell opening is sure to handle seasons of adventuring to come.
Outdoor Research's Helium Bivy, is an extremely lightweight shelter (56g lighter than the previous version) that still manages to retain an insect screen and front pole to give you some wriggle room. There's no rear pole so the leg area is just like a conventional bivy bag.
The groundsheet is made from a tougher material than the shell and is 'bathtub style' to ensure good performance even in very wet conditions. The hood can be fastened back to the pole and you can leave the insect door in place, so on drier nights you can keep the condensation down by leaving the hood open. Although another couple of attachment points would have made tying back the hood a neater proposition.
