I’m a huge fan of wind screens. Even the tiniest breeze can dramatically affect cooking times in the outdoors. and wind screens act both to stop heat stealing wind, as well as reflecting heat, which further increases heating efficiency. When you use liquid fuel or pressurized gas, where fuel consumption is calculated in minutes instead of hours, every tiny bit of heat efficiency is the absolute order of the day.
I have had two other wind screens in the past. This is identical in dimensions when unfolded to my previous versions, but the metal is thinner, which means that when folded, is also less thick overall. It does decrease it’s stability some, but if you find some soft ground to dig in a bit, that won’t be a problem.
All in all, I’d say this is better for backpacking than my older wind screens and I plan to buy more.
If you’re into backpacking and cooking outdoors, this is one luxury that could make a real difference in fuel consumption, and that is worth its weight in gold.
