"I have several pair of Alpine pants, and a pair of winter Alpine pants. They fit and function nearly perfectly. I've never kept any Alpine Light pants in the past because they didn't fit well; the medium size was too small, and the large size was too loose. This iteration resolved everything. Fabric is tougher, but still very stretchy. Weight is minimal, many color choices. They swapped out the ladder loop for an adjustable bunkle. This is now my primary outdoor and climbing pants. My only complaint is that the length is too long, and occasionally, when I take something out of my pocket, the whole pocket comes out with it. Great job BD team, I'll be getting a few more pair."
"I use them for all my adventures, hiking, cycling and climbing , on cold days or hot days they are always a great option to have!!"
"Great quality and color. Seem quite long vs waist size. But I can deal with that."
"Overall good pant for summer alpine rock/glacier adventures. I’d like a less baggy pant with a pocket on the left thigh as well as the one on the right."
"Been wearing Alpine Light Pants for every hike I’ve been on the last few months. It’s the best technical pants I’ve ever owned and I’d recommend it to everyone to get at least one in the closet for use. Black diamond crushed it with these pants. It’s held up to falls, rock abrasions, thorns, sharp leaves, you name it and the pants have been rock solid. Some how this magical pair of pants is warm when it’s cold and windy, cool when it’s hot and muggy. It’s perfect for pretty much all conditions. Biggest worry was that the pants would be too long BUT they have a drawstring that locks into the perfect length for your legs! The pants are super comfy and stretch but also also aren’t super annoying with the crinkly sound. Black diamond thought of everything with these pants and I’d highly recommend them!!"
"I simply love them. They fit perfectly and move without binding or pinching. They stretch and give in all the right places and situations too! They are very durable. We recently went on a 4 day excursion and they help up over all terrain!"
"Love these alpine light pants. Durability, flexible with comfort and classic Black Diamonds commitment to fashion and comfort."
"Best I have owned."
"Confortable and durable"
"The BD Alpine Light *was* one of my favorite pants, until they deleted the zipper on the back pocket, and added a seam across the back of the pant leg, at the knee. I'll keep an eye on future versions, but won't be buying any more Alpine Light pants as they are now."
