I bought a Rab Quantum 250 on steepandcheap for $99.00 free shipping.
I wasn't expecting much for an easy $99 but I am very impressed. I've spent all late spring and summer in my Western Mountaineering Caribu MF which was triple the price at nearly $300.
For a side by side comparison, the RAB feels and appears to have slightly better fabric. In addition, the RAB construction is simple and spot on less the half-zip. I'm actually super impressed with the bag and dumbfounded why others have not bought or given this bag rave reviews for the cost. What a super bag and I'm buying another winter rated bag as soon as I find a similar deal.
