That looks like the pockets are fairly streamlined, and you may not be able to get much into them (nice jacket, by the way). I'd guess that you'd be limited to either a #1 or #2 travel stuff sack. (#1 is really small; Lani has a picture showing it compared to an iPhone). #2 is about the size of the Clear Quarter Packing Cube, but the travel stuff sack can crush down in size. Take a look at the pictures in my
post in the
Windbreaker/light rain jacket in Dyneema pouch? thread. I might also try one of the Eagle Creek Specter II quarter cubes of silnylon, which is slightly smaller than the #2 travel stuff sack, lighter weight, and really smooth to fit into otherwise tight spots. There's a small handle on top to help you pull things out. Conversa talks about using the Specter cubes in the recent "One bagging with the Synapse" thread:

There are links to Lani's Travelite blog review of the travel stuff sacks in my above linked post.
