How Does It Compare To Others?
The Rab Ridge Raider Bivy Sack offers you a little more space than its competitors. The upper layer is constructed of a 3-layer 40-denier eVent fabric that is very durable and has good breathability. The floor is made of a durable abrasion-resistant nylon that is good for setting up on rough surfaces.
The bivy sack is equipped with one DAC Pressfit pole that allows you to hang material in the head area that gives you an internal height for a small shelter. You can carry the pole in an external sleeve and the bivy will need stakes to secure it upright. It also comes with six stake loops, plus a no-see-um mesh door that keeps the bugs out.
For lightweight hikers and mountaineers that are interested in a larger shelter than a typical bivy sack, the Rab Ridge Raider bivy sack is a good option that is just a little lighter and smaller than a single person tent. Suitable for backpacking, hiking, climbing, and mountaineering, the Rab Ridge Raider Bivy is a good choice for winter trips.
In comparison to the Helium, the Rab Ridge Raider stands a little higher offering more space and comfort. They both offer good weather protection and condensation resistance, but the Helium is a little lighter and easier to carry.
For a hooped bivy comparison, the Black Diamond Big Wall Bivy Sac is more similar to the Helium in its minimalistic design. It does not have the headroom of some of its competitors, and it does not use a pole system like the Helium.
Instead, it features a sewn-in flexible wire that automatically suspends the material when you unpack the bivy sack making it a faster and easier bivy to set up.
Made of the Todd-Tex waterproof and breathable material, the Black Diamond Big Wall Hooped bivy has good weather protections and decent breathability while lessening the buildup of condensation. The Todd-Tex material is close to Gore-Tex, but differs by using a PTFE membrane that bonds to the face fabric and internal fabric creating a three layer design.
The Black Diamond also features a no-see-um mesh, taped seams, and a dual zipper. For those that prefer a minimalistic design, but also want a reliable shelter for any weather condition, the Black Diamond Big Wall Hooped bivy sack is worth checking out.
It is suitable for climbing, mountaineering, and can be used as an emergency shelter. While it is easier to set up than the Helium, it does not have headroom and space that you find in the Outdoor Research Helium Bivy.
Another high-quality minimalistic bivy is the Rab Alpine Bivy sack. If you need a reliable and lightweight bivy for a demanding trip, the Rab Alpine is a good choice. It is one of the lightest and smallest packed bivy bags on the market and includes a 3-layer eVent material that has good weather protection and breathability.
The Alpine also features a durable floor made of 70-denier nylon for additional reinforcement. It does not have a pole system that suspends material from the head area with this minimalistic design. To fit technical sleeping bags, the Alpine is mummy shaped, but there is little condensation due to the eVent fabric even with such little space.
The Alpine is a good option for alpinists and mountaineers since it works really well in the snow. The Alpine is lighter and smaller than the Helium, plus it works really well in the snow, but it does not have the space that the Helium provides.
Another bivy from Outdoor Research is the popular Alpine bivy sack that is fairly light and provides decent comfort. This lightweight bivy is made of a 3-layer Gore-Tex Respiration Positive material has good abrasion and tear resistance. Condensation is rarely a problem due to the fabric, plus the floor is constructed with improved water resistance and durability.
The Alpine does use a pole to suspend the fabric above your head, and the pole is easy to carry in a sleeve outside the bivy sack which is secured at the bottom with Velcro closures. Also, the Alpine comes with straps for your sleeping pad, an internal mesh pocket, five-stake loops, internal mesh pocket and a no-see-um mesh to keep out the bugs.
The Alpine is a good bivy for hikers that want a reliable and lightweight shelter for backpacking, climbing, and hiking. Like the Helium, the Alpine provides great weather protection and durability, but the Helium has better ventilation with the zippered hood.
Should you buy?
The Outdoor Research Helium Bivy is a good option for those that want to save money and weight in their pack. This is one of the lightest bivy bags with a hoop on the market, so if you prefer a little more room and ventilation, the Helium Bivy will be a good choice.
