Description

The Nash Blockhouse Overwrap is a full heavyweight overwrap designed for the Blockhouse bivvy. It increases warmth inside the shelter and reduces condensation, making it a practical addition for sessions in less hospitable conditions. The Blockhouse itself is built around Nash's patented continuous frame concept, first pioneered with the bank life gazebos. It goes up in seconds thanks to a fold-out and lock-in leg mechanism, and a fitted heavy duty groundsheet is then laid inside, sealing around the bottom skirt to prevent unwanted visitors such as mice and rats from getting in. The updated edition also includes an additional nylon storm porch that can be extended out for extra shade from the sun or shelter from the rain.
