Merlin UL 30 Sleeping Bag

No frills here; just an ultra efficient slim cut, premium 950+ fill power goose down insulation combined with the light materials. The result is the epitome of warmth to weight ratio for three season hiking. The addition of Pertex® Endurance® shell fabric makes a light bag even lighter! A favorite of ultralite and thru-hikers.

UL: Ultralight. Pertex® Endurance® 10 denier water-resistant/breathable fabric.

Primary sleeping bagReview by Kyle S
This is my primary sleeping bag for the past 5 years and is still doing great. This sleeping bag has kept me warm on treks in Argentina, highlands in Bolivia and Ecuador, as well as throughout the USA. It packs down super small which helps when traveling carry-on to other countries. Continuous baffles work well to maintain down on topside to keep you warm when the temperature dips around 30 or below. Definitely a well made product with quality materials. (Posted on 10/28/2018)
