Down bag washing….

Western Mountaineering's washing tips:

I especially like the dryer refresh idea. 5 minutes in the dryer on low heat seems to perk up my down after a trip.

edit: defer to Pan's instructions

Zak,

The summer JRB quilt you refere to is a sew thru so there are no baffles to be damage (FTR, in the thousands of JRB quilts in customer hands, there has never been a reported baffle failure)

As to clumping, once down is thouroughly dry it will not reclump unless it recieves a another significant wetting.

Two to three cycles of low to moderate heat will normally dry a summer quilt afterwashing assuming a routine front loading washer's spin cycle…. tennis balls are not needed. Check between cycles, break any large clumps felt in early cycles by hand.
