The Helium bivvy itself uses a flexible fibre glass pole to form a hoop shape above your head with a zippable hood which can be pulled down over the hoop to fully zip up the enclosure if required. In good weather, the hood can be withdrawn and toggled up on the hoop, leaving a net mesh to keep bugs out. The standard LNT practices were developed and promoted in the 1970s and 80s after National Park visits dramatically increased from around 3 million (1958) to 20 million (1967). At 20 million, the impact noticeably threatened the wilderness. Today the number of annual visitors exceeds 300 million, but leave-no-trace recommendations have changed very little.

Ample toilet paper, over sized wet wipe for when you are done, odor proof transport bag and as they say peace of mind.The details. Adjustable ventilation panels, various ways to set the doors, zip flaps, and an outer that reaches the groundmake this tent feel like it was made for mountain camping We recently reviewed the OEX Bush Pro Bivvi and feel we have to include it in this roundup of the best bivvy bag choices. It represents fantastic value for money, and pushes the Highlander Hawk really close for the top spot if you’re looking to spend less. In our view, the hood system is slightly better in the Highlander Hawk, but with the OEX Bush Pro being substantially cheaper, it’s certainly a close run decision. This new version of the Helium, released only this year, comes in 14% lighter than the previous generation, and from what we can see there’s been no downgrade in performance either. In our experience, the external bag (which admittedly, was never designed to hold human waste) opens too easily, such as when stored with gear. Still, we've never had an issue with the internal bag or the outer bag–the ones that actually hold waste.
