A modern classic made even lighter, the Prism Ultra Jacket is a slimmed down version of the Prism Jacket. Offering great warmth to weight with an even smaller pack size. Wear as a warm mid layer as an outer layer for any fast and light mountain activities.

Montane says:

Using lightweight and windproof BARRIER LITE RS combined with 25g/m2 PrimaLoft® Silver insulation, the Prism Ultra Jacket is our lightest insulated jacket and is designed to live unnoticed in your pack, perfect for providing warmth as a layering piece or as an outer layer for any fast-paced activity.

Montane's Prism Ultra Insulated Jacket is basically a slimmed down version of the original Prism Jacket. They have removed or simplified some of the features to make it lighter and even more packable. It's not as warm as the Prism Jacket, but obviously it's not meant to be. It's filled with the same Primaloft Silver insulation but just less of it, making it an ideal jacket for those who just need a super light insulated layer they can throw on when needed.

Like I mentioned above the feature set is simple but effective. Elasticated hood and cuffs to keep the cold out, 2 decent sized hand pockets (one doubling as a stuff sack) and a draw cord adjustable hem to trap the heat in. An ideal piece for someone who wants a warm yet super light jacket that won't take up much space in your pack.
