RidgeNote verdict

The Spark Pro sits at the ultralight end of the down-bag spectrum: 900+ fill power is about as high as production down goes, so it delivers its rating at a weight and pack size most bags cannot match. Buy it if grams are your first constraint and budget a distant second; skip it if you want a roomier cut or a bag that shrugs off abuse.
