Looks to me like the Pocket Wing is more of a cross between a kite and a mini parachute ie won't go upwind , maybe go cross wind but definitely more designed as a downwind specific item. Too scooped to go upwind, not aerodynamic enough.
I think the concept of a Wingfoil upwind - deflate/ pack up into backpack - pocket wing back downwind is definitely doable though, keen to try this on my mini DW 105L board
Yes on designer Sam Nokoi's instagram he did say it doesn't go upwind properly but does go well on a reach. Would be great for downwind runs if you could get up straight off the beach and not have to paddle out into the bumps but seems like a one way only thing. I am wondering why they didn't make a more aerodynamic version with more of a foil kite style leading edge then possibly it could go upwind properly.
