Merlin 30 YF Sleeping Bag

No frills here; just an ultra efficient slim cut, premium 900+ fill power goose down insulation, and light yet durable Pertex® Y Fuse shell fabric. Far from basic, the result is a 30 degree sleeping bag that epitomizes the beauty of a great warmth-to-weight ratio for three season hiking.

The Merlin has the slimmest cut of our 30 degree mummy bags.

Our YF line of sleeping bags feature a lightweight, 100% nylon Pertex® Quantum® shell that uses yarns with unique Y-shaped filaments to create a fabric with increased downproofing and water beading properties, even after years of use and washing.

YF: YFuse. Pertex Quantum® 20 denier mini-ripstop fabric treated with a DWR (durable water repellent) finish.

great light weight bagReview by scottmc
I used the Merlin 30 YF for my 2018 Colorado Trail through hike, and it was just right; light weight and not too hot or cold. A lot of loft for the weight. I expect to be using this bag on future trips for many years. (Posted on 9/26/2018)
