The Black Diamond Big Wall Hooped Bivy is a climbing-specific bivy that is durable, easy-to-use, and functional for various conditions. With plenty of space to comfortably lay down inside of the bivy, climbers can stay dry and warm in wet and windy weather.
The Black Diamond Bipod Bivy is warm, sturdy, and very weatherproof, and you can feel secure when hunkering down in even the most unpleasant weather. Although the headspace in this bivy is generous because of the pole, the footpace can be a bit tight, especially when using highly insulated sleeping bags or pads, or when side sleeping. The Bipod is also not the most packable or lightest option on the market, although this could be because of its generous headspace and durability.
