Mountain Hardwear ExtraLamina

The synthetic insulation in the ExtraLamina is designed to retain its loft and thermal efficiency even when damp. Unlike down, which can clump and lose its insulating properties when wet, this synthetic fill will continue to keep you warm in humid or misty conditions.

With a temperature rating of 20 degrees Fahrenheit, this bag is well-suited for late autumn or early spring trips, as well as milder winter nights. However, if you are planning to camp in extreme sub-zero temperatures, you may need a bag with a lower temperature rating or additional layers.

No, the ExtraLamina does not include a draft collar. While it is designed for heat retention, you may want to ensure you have a warm hat or a buff to help seal in heat around your neck and shoulders on colder nights.

The shell material is not water-resistant. While the synthetic insulation handles dampness well, you should use a waterproof stuff sack or pack liner to keep the bag dry while you are hiking, and ensure your tent setup protects you from direct rain or heavy condensation.

This model does not include a stash pocket. You will need to keep essentials like your headlamp or phone in your tent's storage pockets or a separate gear organizer.
