Ocelot Windscreens: A Family of Solutions
The Ocelot Windscreen was designed for people who use mugs along with canister topped stoves. These are great, lightweight cooking options as the stoves are compact and can weight less than an ounce. As marvelous as these devices are, the one area that they lack in is wind protection. All stoves (alcohol, Esbit, isobutane or white gas) all need some sort of protection from the wind. Without a windscreen, fuel efficiency can drop like a rock as well as significantly increase the time to heat up water. There have been a few attempts to solve this problem including the Optimus Crux Clip on windscreen and the Giga Peak windscreen plate. To date, there hasn’t been a completely satisfying solution. A few people have tried surrounding the cooking system (canister & stove) with a partial windscreen with occasional disastrous results.
Enter the Ocelot Windscreen! Ocelot consist of a full circle, yet partial windscreen. Ocelot is design to protect the burner head from the wind while allowing ample space to keep the isobutane canister cool as provide an ample supply of fresh air to your stove. The Ocelot Windscreen is actually a whole family of solutions and consist of a Stainless-Steel windscreen along with a stove specific burner plate that matches your stove to our windscreen. We will be expanding our product line as the product matures. Similar to our other cooking gear, the Ocelot Windscreen has been designed to nest inside your mug: like the Snow Peak trek 700. Of course, smaller mugs can be used however; the specific burner plate may not nest inside your mug. NOTE: below, I have included a few niche mugs that are 900 ml or larger and narrow for those who need larger capacities.
The Ocelot Windscreen was not designed to boil water as fast as possible. If that is your objective, go buy a JettBoil. The goal of the Ocelot System is to preserve fuel efficieny in windy environmets. We aim to be able to boil 2 cups of water using 5-7 grams of fuel and it usually takes about 6 minutes to reach a boil. If you need to boil something fast (like melting snow), just remove the windscreen.

A note about the Ocelot Windscreen. This system was specifically design for canister top stove users who are concerned about fuel efficiency. We recommend that you use your canister top stoves at a low burn rate as that is the proven method of extracting as much fuel efficiency as possible. You should be able to boil 2 cups of water using 6-8 grams of fuel: that means that you should be able to achieve about 16 2-cup boils per 4 oz canister.
Ocelot Performance in the Wind
Here are wind tunnel test results from the PocketRcket Deluxe. The test was run at ambient as weill as with and without the Ocelot windscreen. In all test, 2 cups of 70 F water was used and heated until boiling (210 F at our elevation). At 3.5 mph wind, the Ocleot Windscreen saved 5 grams of fuel per boil. In all cases, the stoves were turned to 1/3 power, increasing the power, lowers the fuel efficiency.
Here are wind tunnel test results from the BRS 3000t. The test was run at ambient as weill as with and without the Ocelot windscreen. In all test, 2 cups of 70 F water was used and heated until boiling (210 F at our elevation). When testing the BRS 3000t, we were unable to obtain a boil an had to reduce the speed to 2.1 mph. In all cases, the stoves were turned to 1/3 power, increasing the power, lowers the fuel efficiency.
