User Review: Mountain Hardwear Men's Lamina 20°

First off, I'm a big fan of Mountain Hardwear (MH) synthetic sleeping bags. I own the Lamina 45, 32, -15 and now the 20.

One of the reasons I stick with this line of sleeping bags is because of their overall comfort and designed compatibility with the MH Conduit SL bivy sack. If I'm going to encounter very wet conditions, I can integrate these bags with the bivy for additional protection and an effective temperature rating of 5-10 degrees lower.

Like other MH Lamina bags, the Lamina 20 is a well constructed bag. At 71" and 200 lbs, I find it offers ample internal volume to assume comfortable positions and rollover. The internal liner has a soft, silky texture that rapidly warms against the body.

I've found the "Thermic Micro" insulation to be highly effective for the bag's weight and to have very good compressibility. I am an increasingly "cold sleeper" but found this bag comfortable throughout the night (wearing a silk weight base-layer) with inside tent temperatures in the low 20's.

Besides effective insulation, MH offers highly compressible synthetic bags. Although not rivaling one of my decent down bags, the Lamina 20 compresses to a remarkably compact package, something I find important when trying to get the volume of my personal gear down, allowing room for crew gear.

It is, in my opinion, a best value sleeping bag. If I could only keep one bag out of the six I own (4 synthetic and 2 down), this would be the one.
