Mountain Laurel Designs Duomid

The MLD Duomid weighs approximately one pound or slightly less, depending on whether you choose the silnylon or silpoly fabric option. This is one of the lightest two-person shelter options available, though the total packed weight increases when you add a separate inner bug net or groundsheet.

No, the MLD Duomid is sold as a tarp-shelter without an integrated insect netting enclosure. In bug-prone areas, you will need to pair it with a separate mesh inner tent—MLD sells compatible Solo and Duo inner nets—or use a bug bivy from another ultralight manufacturer.

The MLD Duomid is a single-pole pyramid shelter made from silnylon or silpoly, while the Zpacks Duplex is an A-frame trekking-pole tent made from Dyneema Composite Fabric with integrated bug netting and a fully enclosed floor. The Duplex is typically more expensive but offers better storm protection and all-in-one convenience, whereas the Duomid is cheaper and more modular but requires separate components for full weather and bug protection.

The pyramid shape of the Duomid sheds snow effectively and is widely regarded as a capable four-season shelter by experienced ultralight backpackers. However, for severe winter use, proper site selection, robust staking, and the use of all guyout points are essential, as a single-pole mid can be vulnerable in high winds if not pitched taut.
