The Mountain Hardwear Lamina 20 is a mummy-shaped 3-season synthetic sleeping bag that is cut a little wider at the legs for comfort. Its two-way full-length zip runs smoothly with little snagging. A large shoulder baffle seals in the heat, and the hood, though basic, fitted well. The drawcords for the hood and shoulder baffle are split into tape and bungee, so in the dark you can adjust the correct one. The inner fabric is pleasant against the skin, while the insulation feels warm and soft. The outer fabric has very good water resistance and is very smooth. The weight is good and the bag compresses down well into the supplied stuffsack. It has a small internal pocket and comes with a large storage bag as standard. But the zip has no Velcro tab to hold it secure at the hood, and rather than a standard-style zip baffle, the main zip has a channel of insulation sewn in such a way that it partially covers the zip.

Verdict: The Mountain Hardwear Lamina 20 is a warm and comfortable 3-season synthetic sleeping bag that’s light and packable enough to carry into the hills. Potential cold spots at the zip let it down slightly. It won ‘Best in Test’.
