The Montane Prism jacket is one of the lightest insulated jackets with a full hood, competing with the MontBell UL Thermawrap parka, which weighs in at nearly the same weight. Our sample jacket is a size large and weighs 12.9 ounces. The Prism has a Pertex Microlight outer shell, two hand warmer pockets and a full insulated hood. The insulation is 0.9 ounce (25 gram) PRISM synthetic insulation. The full zipper is backed by a storm flap. The Prism also features a drop tail, elastic cuffs, reflective flashes, draw cord hem and a beardguard at the chin.
The hood can be rolled up and secured with velcro around the neck. The hood is comfortable, but will not fit a regular size climbing helmet (Black Diamond Half Dome). The hood has a separate draw cord and cinches up tightly and easily. The underarms are designed with Montane’s Enhanced Breathing Panels.
The Prism has a lot of features for a synthetic insulated jacket at this weight, but the insulation is lighter and has less loft than some heavier jackets. This will of course reduce warmth, but perhaps make the Prism usable during more strenuous activity. The hood and full zipper will also contribute to making this a versatile layer. I’m looking forward to getting it into the field. As of the publication date, this jacket is not available from a US distributor.
Complete loft measurements and more details on the PRISM insulation will be included when we publish a full review after field testing.
