"Love them worth the money!"
"Love it. I love Arc’teryx and the LEAF lineup.. this is no exception - super warm, comfortable. Doesn’t “bind” on me, etc. The lets don’t go down very far towards the ankles, they ride up a few inches - this is by design I’m sure, because this is a base layer, just be aware of it. Also, these are warm - so you need to be in genuinely cold weather for them to be appropriate. They are like a mid-weight fleece basically."
"Warm, soft, true to size, and wife wants a pair."
"This product have great quality and are very comfortable. I like band and now almost every clothes of mine are bought from here. Thank you so much."
"As with everything I have ever purchased from LEAF, top notch quality and it definitely will keep you warm. These run to size and are a comfortable baselayer for me."
"Perfect quality as usual! Comfortable! Long lasting!"
"These are a fantastic pair of fleece long johns. They are super warm. I bought a size large and I am 6’ 1” and 175 lbs and they fit perfect. Their shipping and customer service was outstanding."
"Great base layer. Used them in low 20’s for nearly 8 hours. Remained warm the whole time."
"Comfortable, warm and great quality. Used them in temps down to zero and they performed perfectly. Warm, great range of motion and they breath. I just bought a second pair."
"Great design, feels comfy, and keeps you warm! Great at managing moisture, breathes good, but also helps to block wind."
