Mountain Hardwear Lamina 15 - Women's Review

This updated Mountain Hardwear bag is about the same as the previous versions we've tested, with an elevated price tag.

Performance Comparison

Warmth

Warmth is an area where the Lamina exceeds. It is a warm and cozy sleeping bag. The Lamina is rated to 15 degrees Fahrenheit, although we're not sure if Mountain Hardwear EN tests their products, however, we think temperature rating seems accurate. The Lamina is about as warm as other synthetic models we tested. It has more synthetic fill on the top of the bag than the bottom, which is a more efficient use of the materials since we lay on the bottom materials and compress them, making them much less efficient. The Lamina also has large draft tubes and a hood to keep any cold air trying to get in, out.

The Mountain Hardwear Lamina is a bulky synthetic bag that will keep you warm even if it gets wet.

Weight

The Lamina is one of the heaviest bag in this review weighing in at 3.45 pounds or 55 ounces. All the synthetic bags in this review are on the heavier side, but this is over the top and we wouldn't choose to carry the Lamina any distance.

Comfort

This fluffy, warm synthetic behemoth is a comfortable and cozy item. It is a medium fit mummy-shape bag compared to the rest of the field, but not as roomy as the Trestles.

Packed Size

Although this product comes with a compression sack, it is the largest, least-compressible bag of the bunch. Squish all you want; it will still take up a lot of space in your pack. Down products compress much smaller and a better choice when weight and pack space are at a premium.

Two synthetic bags in their compression sacks, the Lamina and Trestles. Neither of which pack down as small as the other down products we tested.

Features

The Lamina is a pretty simple product without many bells and whistles. A new standard feature that many products have added is an anti-snag zipper. We were skeptical at first since these zippers are so huge and bulky, but they definitely prevent the zipper from getting caught on delicate liner materials, and so we are fans.

There is no way your zipper will get caught with the Lamina's anti-snag zipper.

Value

The Lamina has gone up in price recently with its "updates." Unfortunately, we can not call this a screaming deal anymore as other lighter and more compressible synthetic products retail for about the same price or less. It is still cheaper than most down bags in this review with a few exceptions.
