    • Best bag on the market!
I bought this bag 15 years ago and use it almost daily. This bag is phenomenal. The only negative is the price, but like the old adage goes: You get what you pay for! Don't let the price sway you to a different more inferior bag. This bag on Amazon is almost $200 more than what I paid for it 15 years ago, so this is definitely an investment. I've used this bag in below 20 degree weather and it's still super warm and cozy without any drafts cutting through. At first I wasn't nuts about the mummy style, but when it's cold outside it is so worth the tighter fit. Being 6 foot tall I opted for the 6'6" option. That extra 6" is definitely handy because I hate feeling my feet being squeezed. I even use my bag in my house if it's colder than usual outside. I love that it's American made, and Western Mountaineering will refill your bag with down if needed. I'm about to have them do that to this bag. I love how lightweight this bag is. That was my main motive for buying this in the first place. I've gone on several extended backcountry backpack trips, and every ounce counts. If you spill something on your bag, the shell wicks the liquid off immediately and it's easy to wipe clean. I rarely keep it stuffed in its packing pouch unless I'm packing it. I immediately put it in the big bag that comes with it to keep it from being compressed. I hope this review helps someone make the choice to buy a Western Mountaineering bag. They are truly top notch and I don't regret the investment I made 15 years ago. If you take care of it, it will take care of you. Jesus is King! ... show more
