BLACKYAKSibu Hybrid Down Jacket - Women's

Mutant warmth.

The BLACKYAK Women's Sibu Hybrid Down Jacket combines the lightweight warmth of down with the water-resistant performance of synthetic fill, and it might just be one of the most innovative insulated jackets on the market. The Sibu Hybrid features three different kinds of insulation, which consequently makes it ideal for ski touring, alpine climbing, and training at base camp.

Starting from the top down, the 750-fill down insulation atop the chest provides crucial warmth to sensitive organs. Not to mention, this same down insulation is treated with a water-resistant coating to prevent moisture from compromising your warmth. Next up to bat is the PrimaLoft Gold, which ensures furnace-like fervor when wet. The final part of this insulation trifecta is the Polartec Alpha located all along the back of the jacket: this strategic baffling is designed to provide warmth and breathability, so you don't end up with an over saturated backside, say when you're wearing a pack. The Cordura inserts offer unimpeded mobility, while the elastic bound cuffs and hood provide a secure fit. Additionally, the Polartec Power Grid and Thermal Pro fleece enhances moisture management, dries quickly, and ensures stretch when you need it most.

Gorgeous but Too Restricting

  • Familiarity: I returned this product before using it

This is the down jacket I'€™ve been searching for as far as flattering design and warmth...but sadly, it'€™s very restricting across the chest when I moved my arms. For anyone that may have broader shoulders, this jacket will be too tight for active living. I'm 5'€™7, 125# and I tried a medium. Beautiful jacket, wish I didn'€™t have to return!

fits small

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: large

I absolutely "loved" this jacket - stunning design, colors, finish and smart design. BUT they fit VERY small. I am a large at best, sometimes fit into a medium. The large was too small, in arms and breast - zero room for boobs! Which is a little weird as it is a woman's jacket. Frustrating as it is a stunning jacket.
