This 3-in-1 style jacket has a waterproof outer shell and an insulating down liner. The outer shell is lightweight and extremely compact, made using 2.5 Paclite technology from GORE-TEX. The down liner uses high quality goose down in combination with lightweight fabric. Either jacket can be used by itself and the low-key design doesn't look out of place in a business setting.

About the material: EX Down

World class, high quality down
Montbell's premium down comes from water fowl that live in regions with seasonal temperature extremes. The down balls from birds in such regions are characteristically much larger.
Large down balls hold more warm air, which translates to needing less down to provide exceptional warmth retention.

Lightweight yet warm
When compared by weight to lower quality down, an equal amount of premium down is loftier and has better warmth retaining properties.

Sewn through construction

In sewn-through construction, stitch lines go from the exterior of the garment directly to the lining material to join the two layers, creating small pockets for down insulation. This simple method provides an economical way to keep down in place, while leaving the garment as light as possible.

Maintenance of Down Leakage Warning (38-102)

In the event that small feather spines or down clusters work their way through the fabric it is best to reach behind the fabric and pull the offending down cluster BACK INTO its down chamber. Gentle massage of the area will promote "self sealing" and re-align the fabric threads, while better distributing the down insulation. If at all possible avoid attempting to pull the cluster from the bag or garment. Doing so can cause the exposed cluster to tangle with others and draw them from the chamber.
