I have this tent: Fjord Nansen Tromvik II. It's very well built and thought-out, lightweight (around 2kg / 4.5 lbs) and is a pleasure to sleep in during summer / early autumn. However, since it's so lightweight and very well ventilated (with outer fly not even touching the ground), in windy conditions it feels almost like sleeping without a tent :)
I don't want to buy a second tent at the moment. Is there a simple / inexpensive way to wind-proof this tent? Shall I buy some cloth and sew it to the external tarp to create a skirt?
