TOP 3: What is it? Well, aside from one’s next to skin layer, it’s clothing that is worn on top. Yes, I know some people have shorts, gaiters, merino leggings, sleep clothes and pants, etc, but for my purposes I only wear pants (which I wear to bed) and trail runners. The real secret sauce is how do you layer for anticipated conditions and unanticipated conditions? For instance, I never go on a jaunt without a proper rain jacket. In my case I pack a Timmermade Silpoly Megazip pullover. Despite all the wonder jackets out there that cost upwards of 1000 bucks, it has been proven that when one is expending energy, be it just walking or laboring uphill, eventually the jacket will wet out when it is no longer able to move the body’s moisture through the membrane and outer layer, especially in high humidity. Silpoly is a non permeable fabric, 100 percent waterproof. The key to it, and any other top piece, is ventilation. I’ve spent entire days in rain with a DCF poncho, but my core was dry because of the venting options on it. The Megazip lives up to its name in that there is a zipper on each side running from wrist to hips, along with a quarter zip in the front. Now I usually plan my short 3 day trips over good weather, but in 2024 I was trying to pull off a YoYo and the weather was just not cooperating. That Megazip was on and off constantly, especially in heavy mist where it’s not technically raining but everything is wet. It functioned well as long as I kept on top of the venting. This, of course, is also valid for a wonder jacket if it has good side and front zips, but the Megazip is a mere 5 ozs, packs very small, has a roomy fit (most pullovers are wider than zip jackets) and long to cover my hips.
