Outdoor Research Echo Hoodie

“I have all 3 primary weights of AD hoodies (as well as an oddball 105gsm flex version), as well as an R1 and an R2. Love Patagonia, and the current Airshed Pro is my favorite “shirt” currently. To answer your question, an AD 90 is almost as warm as an R1 in totally static conditions with no wind. An AD 120 is significantly warmer, almost to R2 level. But… an AD 90 lets air pass through so much better than an R1 that with even a light breeze it won’t be as warm. That’s where the Airshed Pro comes in, as it’s incredibly breathable (it’s the same fabric as the out layer of Nano Air at 50-60cfm). It blocks just enough wind to make the AD most effective while not forcing sweating like a rain jacket would. So I keep either an AD 60 or 90 with me to pair with the Airshed and I also have a Versalite for rain. The Airshed is super comfy and provides some sun coverage as well as being effective against bugs. I’ve started wearing it as a shirt in place of my OR Echo or Jolly Gear UL. The weight of the AD hoodie and Airshed together is still significantly less than an R1, so I don’t mind the additional wind layer.”
