Mountain Hardwear Lamina Sleeping Bag

Traditional sleeping bags use needle stitching that creates small holes, allowing heat to escape and cold air to seep in. The Lamina’s welded construction bonds the insulation directly to the shell, eliminating those seams entirely and removing the cold spots that typically develop at stitch lines.

Yes, it is an excellent choice for damp environments. Because it uses synthetic insulation rather than down, it retains its loft and thermal efficiency even if it gets wet, and the water-resistant shell provides an extra layer of protection against condensation.

The bag is anatomically mapped to better match the female form, typically featuring a slightly different shape in the shoulders and hips to minimize dead air space. By reducing this extra space, the bag can warm up faster and retain heat more effectively.

This model features a left-hand zipper, which is standard for this specific design. Generally, it is not designed to be zipped together with other bags, as the mummy shape and specialized construction are optimized for individual heat retention.

A 0-degree rating indicates the temperature at which the average person should remain comfortable, but it is a baseline, not a guarantee. Factors like your sleeping pad's R-value, your clothing, and your personal metabolism will significantly impact your actual experience in freezing conditions.
