My wife hates her mummy...to confining. Currently she' s using a 20 degree Cat' s Meow by The North Face. Not exactly light by UL standards but the price was right and it's under 3lb. I've been trying to find something a little roomier that's functional and reasonably priced. Campmor has a Slumberjack Super Guide 30 degree Thermolite Extreme...Isn't that a mouthful...(2lbs 5oz) for $60. The stats sound pretty good but I don't have any experience with slumberjack quality, durabilty, accuracy etc,etc.Any feedback or other suggestions would be appreciated.

If you are going to spend the money anywhere, spend it on whatever it takes to make your wife comfortable. Mine has a Western Mountaineering Aspen, but she could have had anything she wanted. In the long run, having her go with you is cheaper than leaving her at home. The Aspen costs a multiple of $60, but it will open flat, and will sleep two with its summer "coupler", and it will double as a quilt in the hammock on your solo trip.
Good luck at your $60 price point. I have my doubts about Slumberjack vs your existing bag.

Wrong assumption.Like you there's not much if anything that I would deny my wife, especially if the alternative is not having her join me on my adventures. I also outfit our 4 children who are also avid hikers. (consider 6 bags at an average price of $150 ea = $900... it adds up quick)I don't have a problem purchasing high priced, high quality gear but when outfitting six it only makes sense to make sure you're getting the best bang for the buck. (why pay a higher price for Tylenol when you can buy acetaminophine for less). I understand of course that this doesn't always translate into the gear world and hense the question about the durabilty, quality,etc of an off brand like slumberjack as opposed to a name brand like Mountain Hardwear who provides some of my favorite gear. Don't mean to sound defensive but I am when someone suggest that I'd skimp on my wife. Thanks for the recommendation of the WM Aspen I'll take a look.
