The Mountain Hardwear Lamina 20 is one of the lightest sleeping bags on test and, as a result, it packs down small in a good stuffsack. There’s a great two-way zip that doesn’t snag, and a substantial baffle alongside to eliminate cold spots. The hood is big but feels extremely cosy when pulled tight, and both on this and the generous shoulder baffle you get drawcords split into cord and bungee to make sure you pull the right one at night. There’s also a very small pocket on the outside. The bag feels large and roomy, which will suit some, but smaller people might prefer a snugger fit. But when done up tight, the hood ended up covering my nose and made breathing difficult. The drawcord enclosures are also insulated, meaning they felt bunched up when tightened. These two niggles are drawbacks that nudge the Mountain Hardwear Lamina 20 down the rankings a little.
