Reproduction Belgian Armed Forces equipment, made in Australia.

Available in AUSCAM (DPCU) & NAVY

Re-designed, tested and manufactured in Australia, this Bivy Bag features exceptional design qualities, heavy-duty construction and premium materials.

The original vintage MK1 Belgian Army Bivy bags are now almost impossible to find in serviceable condition. Originally designed and manufactured by Seyntex for the Belgian Army, these Bivy bags were incredibly popular with outdoor enthusiasts and military personnel over the past 30 or so years. Incredibly light-weight the MK1 Belgian Bivy was cutting edge kit for its era. Simple design with the ability to act as a bed-roll, they are still prized possessions of recreational hikers, climbers, hunters, etc.

Highly sought after by European customers, we sold hundreds of these to both Australian and International customers but ran out of stock when we bought and sold the last pallet of surplus stock from the European warehouse.

We now offer this limited-edition listing of re-production / improved MK1 Belgian Army-style Bivys with some modern touches.

We replaced the old light-weight weather-resistant cotton & Seyntex material with modern waterproof breathable technical laminate fabric. The fabric draw-strings and ties have been replaced with heavy-duty nylon equivalent with quality barrel locks.

The new & improved Mk1 Bivy features Velcro™ tags to hold the storm flap in position and a loop to lift the material up off your face. Improvements also include full seam sealing to all internal stitching & joins to deliver a 100% waterproof unit.

Unlike the original weather-resistant version, the Improved Mk1 Bivy Is now suitable for use in all-weather types and conditions thanks to the high-tech laminate fabric and seam sealing.
