This is a very comfortable knitted fabric top with little branding on it that gives you a very sleek look. Breathable too, so even if it feels midweight, you will be able to do your activity of choice with no problems.

Nike ACG Men's Dri-FIT Mid-Layer 1/4-Zip Trail Running Top is definitely a comfortable top to wear for a run on the trails or any other activity. The soft lightweight texture of the material feels wonderful on my skin. It fits true to size , I'm loving the optional thumb holes in the sleeves. I like the 1/4 zipper , and when its zipped all the way up it's not touching my face , which I find myself annoyed by the ones that do. I thought the material might be one that will easily get snags but so far I have been proven wrong. Nike did good with the design of this shirt and I see myself wearing this often on the trails.

The Nike ACG Dri-FIT Mid-Layer 1/4-Zip is easily my new go-to for outdoor training. I picked this up specifically for trail running, and it handles the demands of the trail perfectly. The fit is spot on—it is completely true to size and moves with you naturally without feeling restrictive. It is the absolute perfect weight for cool morning runs; it provides just enough warmth to take the edge off the morning chill, but the fabric is incredibly breathable so you don't overheat once your pace picks up. I especially love the addition of the thumbholes, which keep the sleeves locked in place and add that extra bit of coverage for your hands before you warm up. If you need a high-performance, durable mid-layer for the trails, this is worth every penny.
