When temps drop and your hiking gear is soaked with sweat, you're forced to make a tough call—keep going or turn back. These ACG Wolf Grid trousers are designed to keep you out there. The breathable grid-back fleece adapts to changing conditions. It wicks away moisture and stores your body heat to help you stay warmer with less, so you can experience more.

Wolf Grid Construction

The perfect package—warm, dry and breathable. Contouring chessboard-patterned fleece feels soft and light on your skin. The raised square sections help store your body heat for warmth. The low square sections rest closer to the skin to help wick sweat through thin, breathable channels and away from your body.

  • ACG Might as Well Stand for Always Comfortable Gear!

    George

    I've been looking for a pair of pants like these for nearly two years, and I think I've finally found them! I had an old favorite pair of workout pants that I'd worn for years. They were my go-to for just about everything during the fall, winter, and spring, but they were getting worn out and needed to be replaced. Unfortunately, everything I tried was either too tight around the ankles, fit more like tights or joggers, wasn't made from comfortable material, or was so heavy that it was only practical when it was really cold outside. These Nike ACG Therma-FIT pants genuinely check all the boxes I've been looking for. They're incredibly lightweight, stretchy, and comfortable. As someone who tends to get hot easily, I've always found that the best pants for hiking and other outdoor activities are ones that are lightweight and breathable, but can still retain some warmth when the temperature drops. That's exactly the kind of balance I was looking for in these pants. The fit is relaxed without being overly baggy, and there's even enough room to comfortably pull them on over a pair of running or basketball shorts. I also really like the subtle pattern in the material. It's unique enough to give them some character without being too flashy, making them great for everyday wear. I honestly don't have any complaints so far. If they continue to hold up as well as they've performed initially, I'll definitely be picking up at least another pair in black and hopefully some other colors too. I know ACG stands for All Conditions Gear, but in this case, I think it could just as easily stand for Always Comfy Gear!

  • Great Quality but Runs Small

    FitMom2124

    I appreciated the quality of the fabric of these pants. The fabric is thick enough that they keep me warm in chilly weather and I didn’t feel a breeze. They do run a little small. I got the xs based on the size chart and wish I had the small. They are very tapered and were tight in my hips and calves. I did like the slight texture design on the pants. I was able to wear these pants on my trail walks and also while doing yard work. They are comfortable while not being too stiff. If I were to get these pants again, I would order a size up.

  • Lightweight and Warm!

    Sun

    I got these Nike ACG Wolf Grid Men's Therma-FIT Hiking pants in a size XS. My main purpose for these is for trail walking in the fall weather. The XS was a great fit in the legs and in height, although I found the waistband to be a bit more snug than I'd like. The material is great. Its lightweight, breathable, stretchy and WARM! The inside of the pants is lined with a thin fleece material which makes these perfect for the fall or spring season. I like how the two pockets are roomy, and deep enough to hold my phone without it sticking out, and they zip, so if you are jogging, nothing is falling out. The ankle is tapered a bit but not so much that it is jogger style. They are comfortable enough to wear all day, and casual enough to be worn even when not exercising. Overall, I'm really happy with them. The only thing I would change is the waistband to be not quite as snug, and it would also be nice if they had at least one back pocket as well. I definitely recommend these pants if you are active outdoors and need some comfortable flexible, and warm lightweight pants!
