This is hands down the best bag I've owned. I'm a big guy as well and it is extremely comfortable and warm down to 15 below. It can be used as a blanket on a bed or hooked up to another bag.

There are so many ways to control the warmth that you can vary the temp inside the bag for summer or winter depending on how you configure the zippers. It's like a fluffy heated cave that has plenty of room for cloths at the bottom of the bag and keeps them nice and toasty.

You will not regret this bag by any means. It is worth every penny.

Once you go Western you won't go back. This is by far the most comfortable bag I have ever owned. I have slept in 20 below with a BA pad and was plenty warm. For a guy of my size (6' 3" 225 #s) this fits me perfectly.

Price Paid: a lot

I purchased this wonderful bag for my son who is 6'2" tall and weighs 225. He loves it, but never gets to use it because I'm using it. I have a -30 bag from Sierra Designs, but prefer his WM hands down!!

Version reviewed: MicroFiber

This is the best bag I have ever owned. I am a large man that likes to move a little during my rest and this bag has plenty room. The 1.9 oz. microfiber is extremly comfortable.
