"My favorite piece, period."That's what Peter Whittaker says about the Igniter. He wears it on rest breaks when guiding on Rainier. And in Sun Valley when he's alpine skiing. The PrimaLoft One insulation keeps you warm even when wet. Light and highly compressible, it packs easily. This is the ideal base camp or belay jacket, or your outer layer on ascents of sub-8000-meter peaks. Machine wash. Precision layering.
