I picked up one of Flat Cat Gear's Snow Leopard windscreens for the Kovea, on EBay. The 1.1oz Snow Leopard works for mugs and small pots, and packs away nicely inside the 700ml -800ml mug/pots, but will interfere with packing an 8oz canister inside. Flat Cat also makes a larger screen for pots, the Bobcat.
Brett919Just wanted to add: Getting a lighter close enough to light the stove (with the windscreen on) can be a little challenging, especially with cold fingers. I used matches, which can be a PITA to get lit in the cold too. Don't know if I want to carry a small fire steel or striker but I may test how it lights with sparks. Everything else about the windscreen I like.
Brett919I think it might be the cold affecting the lighter that might be the problem. Lighter fuel is butane after all. I use an electric lighter with the button switch so I can use it with gloves on but it'll get finicky below freezing. I eventually resorted to carrying a firesteel as a backup and it works great with this stove.
PaperCloudGood point! I was overlooking that. I did purchase an electric lighter some months ago but 1 of those seems to be the same weight as 5-6 butane lighters. The trip after this one I did use a small (~1-1/2") fire steel, it worked but I could probably improve my technique as it often took a few attempts, or maybe a slightly longer fire steel.
