Multi-Down Insulation Fill:
Why? Trying to balance the Pro's and Con's of down vs. synthetic fill is the never ending debate of the outdoor world. While there isn't an exact answer, in short: Typically Down is Warmer but Synthetic performs better in Wet Conditions.
So we asked ourselves - Why not use both! By using both we're maximizing the benefits of both materials while aiming to limit their imperfections
How? The M-3D's outermost top and bottom layers uses StratusLoft to maximize it's performance in wet conditions. The 650-Fill-Power Down uses it's amazing heat trapping ability in the layer closest to your body. A win/win!
