Adidas Outdoor 37.5 Half-zip Long-Sleeved Shirt Review

Adidas Outdoor 37.5 Half-zip

The purpose of Cold Outdoorsman is to document my experiences with gear that might help me overcome my battle with Raynaud’s syndrome. If I can overcome the cold, I’ll be less reluctant to get outdoors and will be able to set a better example for my kids. At least that’s the theory. My adventure’s about a year old, so I still feel self-conscious at times about wearing warmer clothes when other people aren’t. The Adidas Outdoor 37.5 Half-zip shirt let me break that barrier.

Like many clothes from Adidas Outdoor, the 37.5 Half-zip is billed as a technical athletic piece. The biggest feature is right there in its name. The long-sleeved shirt uses “37.5” material, which incorporates activated carbon to wick away moisture and keep you dry. The material is super light, as the entire shirt weighs just 5.7 ounces. This combination of wicking and weight is marketed as important to keeping you cool, which it is. But staying dry can also help keep you warm, which is what most intrigued me.

Unlike the shirt’s billing, I’m neither technical nor athletic. Instead, I turned the Adidas Outdoor 37.5 Half-zip shirt into my own sort of Raynaud’s camouflage. Whether I was hiking, camping or kayaking, I never felt self-conscious about wearing this long-sleeved shirt. Because it’s lightweight, it was easy to play-off its technical advantages. Because it has UPF 25, I could say I was monitoring my skin’s health. I certainly appreciated both of those technical aspects. But I predominantly wore the shirt because it offered a stealth base layer for my outdoor pursuits.

The shirt is black, so I was worried it might actually overheat in full-sun activities. It didn’t, probably because the 37.5 material is so breathable. I especially appreciated that while kayaking on Mt. Hood’s Frog Lake, where the breeze kicks up in the afternoon and sends me scrambling for some insulation. The Adidas Outdoor 37.5 Half-zip shirt is hardly a parka, but it provided just enough wind protection to take off the edge.

My only issue with the Adidas 37.5 half-zip is ironically tied to its athletic billing. Again, I’m no athlete, and I have about the farthest thing from an athletic figure you’ll find in Portland. The shirt is light and tight, so it grips areas a self-conscious person might not want to have gripped. Like, say, moobs and love handles. It took me a while to get used to the combination of lightweight material and trim fit, and I won’t say I ever really got emotionally comfortable with it. But I was able to bite the bullet because I appreciated the benefits the shirt provided, including the ability to wear long sleeves without getting sideways glances.

I can’t imagine the Adidas Outdoor 37.5 Half-zip shirt offering much in winter, but for outdoor pursuits from late spring to early fall, there’s no question it’s a good option.
