— Vinny G. (4/5)
"The baselayer bottoms fit really well and make a big difference when wading in 40 deg water temps."
— Jason F. (5/5)
"Wear them nearly daily in the winter whether it be on the water, the slopes or to work. Fantastic pair of base layers."
— Stuart (5/5)
"Perfect fit and exactly what I hoped for. Extremely warm and comfortable, also. All you need underneath. They have plenty of room, so order whatever size you wear. Very good purchase!"
— William M. (5/5)
"These pants are well made and fit well. My only comment is that they're not really that warm for winter fishing, which is disappointing. I'll wear them in the shoulder seasons (fall and spring) but not in winter."
— flyfishpatriot (4/5)
"Great for the cold days when layering up to head out on the water. Not the skin tight fit that some brands have and allows for long periods of warmth"
— Sean M. (5/5)
"Haven't used them yet, but fit & feel excellent. Am expecting great results."
— John S. (5/5)
"Nice, but I can't wear them. Too big"
— Alejandro E. (5/5)
"Amazing"
— James C. (5/5)
