This is a delicate fabric and must be treated as such! It will snag easily, so keep it away from Velcro, dog claws, and definitely don’t bushwhack in it!

Im totally in love with this mock neck. It is absolutely perfect for a cool night. I recommend it 100%. It looks good to!!!
It's everything I've wanted in a hiking fleece. The material is insanely light and very breathable but still warm, especially when you layer with a wind layer. My only complaint is that I wish it had something to cinch it at the bottom. All in all, it's something I can feel confident throwing in my pack whenever I head out on the trail.
I love this layer! It's warm as soon as you put it on, yet incredibly light. The fit is perfect, and I love the option of having a zip-neck.
I wear this 1/2 zip all the time, one of my favorite pieces of gear from SamBob. The fit is true to size, the zipper is smooth and the color is so cool- it changes with what your wearing, reflective like Sea Glass!
What perfect timing you had coming out with a 3/4 zip fleece. I was beginning to think I would have to make my own, and even though I can do it I didn't want to, lol. It has performed very well on my trip to Ireland and then to Greece. Thanks again!
