I know this base layer is made for winter, but it also works perfectly for me in the summer too. I guess I wear some of the same gear in the winter as the summer, the base layer mesh and then this 2nd layer mesh over top, and then over that just a simple birds eye mesh long sleeve shirt and it is nice and cool in the summer heat and it just works for keeping me cool and the sweat dries fast. Best of all, bugs simply cannot get through this three layer system I'm wearing during summer and they can't feast on me, so it is also a great mechanical bug layer too. I do treat my outer layer and 2nd layer with permethrin as additional protection. It's been an absolute horrible buggy season up in the mountains and it's hot too, and because there are so many bugs I need to cover up completely, but I find this system works well for me and keeps me nice and cool and best of all, no itchy bug bites!

I have been using this second layer mesh over the base Wiggys mesh. Over all this I just wear a simple and cheap long sleeve polyester shirt, and it works great for hiking in the sub freezing cold. Recently it was in the teens and I wanted to go for a hike and I decided to start off cold and with this basic setup out and I still found myself at times quite hot, and noticing I was keeping very dry and not once did I ever get too cold and the sweat was mitigated almost instantly. Stopping for lunch I did put on a lightweight wind breaker and I was perfectly at temperature until it was time to go hiking again, when I peeled off the wind breaker and was back to just wearing the poly shirt and these mesh layers. Overall, I find its quite a comfortable setup for an active cold weather hiking session and I simply can't believe these mesh base layers aren't more wide spread and known amongst the ultralight hiking community. I weighed my second layer mesh at a mere 4oz, my base layer mesh shirt was just 9oz, unbelievable! What a great technology and I'm so glad I found this clothing and best of all it's made right here in the USA. I've had issues with other wicking fabric and feel quite cold spots such as when I take off my backpack and feel a very cold spot on my back due to the sweat or cold forearms and underarms, but with these layers, I am just always warm all over and when I do sweat, I'm still warm and if anything, I'm actually feeling hot to the point where I feel like I need to open ventilation zips on my outer layer. Even my merino layers get cold when wet, but when I get these mesh layers wet, I'm just warm and comfortable and, well dry!
