Merino wool fishnet long john update: First longer coldish weather ride with the merino wool fishnet top (I don't use the bottoms until around zero). 22˚F starting out, dropping to 10˚F on top with 30mph winds, then warming up to 32˚ F dropping back to home. I continue to be amazed by this system and the dry warmth it allows. Fishnet long johns really are a completely different category and require a completely different method of managing warmth. They give an amazing range of temperature flexibility with far less clothing brought along.
With regular tight-knit long johns they get sopping wet at aerobic activity levels. When climbing, there just isn't airflow to keep them dry unless there happens to be a significant wind (at which point it's pretty cold on the skin, regardless of wool or cotton). It's easy enough to stay warm when wet AND active. Stop? OR head downhill? Or encounter significant winds? Danger zone quickly sets in. Fishnet changes this by allowing vapor to pass through the cotton flannel shirt (could be any kind of shirt). The air gaps on the skin mean sweat is a vapor instead of liquid, and makes it easy for it to escape with ventilation. Still gets a bit wet, but that too is held off the skin, so I stay warm until it evaporates. The harder I work and/or the warmer it is, the more I increase ventilation (include untucking my shirt so movement acts as a billows promoting air flow. The trick is to not get warm when aerobic. Stay slightly cool. Then, when stopping or heading down hill, don the breathable ventile windproof waterproof shell and stay warm, and there's no wet to cool me off. I'm curious to see how just the fishnet top with a non-cinched down ventile jacket (for max air flow) works in rain at lower temps (32˚F to 50˚F), especially multi-day backpacking. That scenario is always challenging and is the second most challenging danger zone (after extreme cold below zero). Anyone have experience with this?
