SO trying to decide between the Sitka and the Stone glacier PUFFY PANTS/JACKET Any thoughts? Stone glacier Grumman Jacket is 11.8oz and pants are 12.7 and the Sitka are Hyper down jacket is 1lb 4oz and pants are 1lb 3oz. Anyone have experience with both? Is this one thing that its worth adding a little weight( its feather right, don’t weigh much LOL) Is this. A ford Chevy thing?
