Solo and Custom Duo Sizes

2004 MLD Innovation: The first DWR top SuperLight Backpacker Bivy with a net window. Still The Best!

• Pro Level SuperLight Bivy™
• MLD Mountain 10D 3X DWR Top
• Pro Silnylon OD Green or White .75 Cuben Fiber Bottom
• Deep Side Zipper for easy entry/exit.
• Original Design: First DWR Backpacker Top Style Bivy with a Net Face Window.
• Oversize for zero sleeping bag loft compression plus extra head room for some gear inside.

This is the bivy used by Andrew Skurka on his incredible 4700mi Alaska -Yukon Expedition. -


What are the main functions of a water resistant (not waterproof) bivy like the SuperLight Bivy?
1: Part of the total sleep heat retention system - adds 5 - 15 degrees of warmth - especially if any slight wind at all get under/around your shelter.
2: Bug Protection
3: Built in Ground Cloth
4: Protects from any blown or splashed rain /snow that nets in under your overhead shelter.
5: Saves weight from the total shelter system. It's a 7oz multipurpose piece of gear that allows a lighter sleeping bag, no need for a ground cloth or a separate bug protection system. Allows the use of a smaller overhead shelter.
6: Can be used alone for night temps above about 65 degrees when you do not need a sleeping bag but do need some wind/ water protection, a bit of warmth like a sheet and bug protection.
7: Can be used alone with no overhead tarp for cowboy camping.
8: Pairs perfectly with a backcountry style quilt to limit warm air venting during night moves.
9: By putting your sleep pad inside the bivy you increase the sleep pad/system thermal efficiency by limiting convective heat loss.

• #3YKK zip with two dual sided pulls extends to waist for easy entry and exit.

• Least expensive truly Ultralight High Performance bivy made.

• Large Half Moon bug net window over the face is large enough for good ventilation. We've tuned this window size just right to for the right balance of ventilation, low condensation and heat retention.

• Optional all bug net head- recommended for primary use in warmer climates and warmer seasons with night temps mostly above 45 degrees. This is also a better choice for very rainy and extra humid conditions and can lower condensation inside the bivy when you sweat or are forced to wear damp clothes while sleeping.

• Mummy shaped with large volume head and foot area.

• Overhead hang loop positioned over the face. Clip it up under your tarp/shelter to create more air flow around the head.

• Four drying hang loops- NOTE: THEY ARE NOT STAKE OUT LOOPS!!! if you use them to stake the bivy use small bungee cord and stake loosely...they are not intended to function as the corners like tent bathtub floor.
