Product Information

Full details

The Rab Ark Emergency Bivi is an essential safety tool for mountain explorers, hikers, and alpinists who need a reliable, ultralight shelter for survival situations. Its primary benefit is its ability to reflect body heat back to the user, providing critical warmth during unexpected weather changes or emergency overnight stays. While it is highly effective for protection, users should note that it is designed as a minimalist emergency aid rather than a replacement for a full-featured sleeping system or long-term shelter.

FAQs

Is this bivi reusable?

Yes, the Rab Ark Emergency Bivi is designed to be durable enough for multiple uses, provided it is handled with care.

Can I use this for normal camping?

It is intended as an emergency shelter. It lacks the breathability and comfort required for a standard tent or dedicated camping bivi.

How do I clean the bivi?

Wipe it down with a damp cloth and mild soap if necessary, then air dry completely. Do not machine wash or tumble dry.

Will it fit over a sleeping bag?

Yes, it is spacious enough to be used as a cover for a standard sleeping bag to add extra weather protection and warmth.

What is the primary material?

The bivi is constructed from a specialized technical fabric designed to be windproof, waterproof, and heat-reflective.

Troubleshooting

Bivi feels damp inside

Condensation is common in waterproof shells; ensure you vent the opening slightly if the weather allows and try to keep wet clothing away from the interior walls.

Difficulty getting back into the stuff sack

Don't try to fold it perfectly; instead, stuff the material into the bag randomly to avoid creating permanent creases or damaging the waterproof coating.

Pros and Cons

Pros

  • Extremely lightweight at only 105g
  • Highly packable size fits in small spaces
  • Effective heat reflection for emergency warmth
  • Fully windproof and waterproof taped seams
  • Simple, intuitive deployment for high-stress situations

Cons

  • Not intended for regular, non-emergency use
  • Minimal breathability due to waterproof material
  • Provides no padding or comfort features

Setup, Compatibility & Care

Deployment is straightforward: shake the bivi out, enter through the opening, and tuck the top edge to minimize heat loss. Compatibility is universal; it works over any standard sleeping bag or over your existing clothing layers. For care, always allow the bivi to air dry completely after use before folding it back into the stuff sack. This prevents moisture buildup and material degradation. Avoid storing it in compressed states for extremely long periods; it is best to pack it loosely into its sack only when heading out on an excursion.
