AquaQuest Pharaoh Bivy Sack — Ultrallight Waterproof Shelter, Olive Drab, 10,000 mm Rainproof & Breathable

The AquaQuest Pharaoh Bivy Sack is a waterproof, breathable outer shell that encases your sleeping bag and pad to create an ultralight, low-profile shelter for wet or windy conditions.

Designed for minimalist campers, bikepackers, mountaineers and thru-hikers who prioritize weight and weather protection, the Pharaoh pairs a hardy 70D nylon shell with high-performance membrane ratings for rain-shedding and vapor transmission. It adds a lightweight layer of weather resistance and some peripheral insulation without the bulk or setup time of a tent.

How does the Pharaoh keep you dry in heavy weather?

The outer fabric has a 10,000 mm hydrostatic head rating, which prevents liquid water from penetrating the shell under typical storm conditions. At the same time, the material is engineered to move moisture vapor outward so condensation inside the bivy is minimized when you’re breathing or sweating.

• 10,000 mm waterproof rating to resist driving rain
• 10,000 g/m²/24h breathability to reduce internal moisture buildup
• Seam construction and elasticated hood to limit water entry points

Will it fit my sleeping bag and pad comfortably?

The Pharaoh is built with a universal, single-person shape that accommodates users up to 6'6" and most standard sleeping bag/pad combinations. Dual-side zipper access makes entry and exit easier and lets you ventilate or reach gear without fully exposing yourself to the elements.

• Roomy internal volume for single sleeping systems
• Two-way zippers on both sides for flexible access and ventilation
• Designed to work with pads to maintain insulation under your body

How lightweight and packable is the bivy for multi-day trips?

Weighing only 1.1 pounds, the Pharaoh keeps your base weight low and compresses into an integrated stuff-sack for easy attachment to a pack or bike frame. Its cylindrical packed size (about 9" long by 5" diameter) tucks into external pockets or strap systems without dominating precious cargo space.

• Net weight approximately 1.1 lb (ultralight for a weather shell)
• Built-in stuff-sack compresses to 9" x 5" for tight storage
• Low-profile shape meant for streamlined carry on long ventures

What features help in severe conditions or overnight storms?

The hood has an elasticated drawcord so you can cinch the opening down against wind-driven rain while still retaining some peripheral vision and ventilation. Durable 70D nylon construction resists abrasion from rocks and vegetation while giving added peripheral insulation compared with a naked sleeping bag.

• Elasticized hood to seal out wind and precipitation
• Robust 70D nylon for abrasion resistance and durability
• Minimalist footprint for quick setup and reduced snag risk

Who is this for? The AquaQuest Pharaoh Bivy Sack suits ultralight-minded adventurers who want reliable, packable weather protection without pitching a tent—backpackers, solo campers, bikepackers, winter day-trippers and emergency-prep kits. If you value compactness, waterproof performance and simple functionality over interior living space, the Pharaoh gives you a stealthy shelter that protects your sleeping system from rain, wind and ground spray while adding minimal weight to your kit.
