Fantastic Thermal Top Layer Review by Jerry Hubka
I purchased this Fleece Top for future Alaska fishing trip this Fall, but I took it with me to Ireland and Scotland in late April and most of May just to test it out. Both countries were having unusually cold and rainy weather for this time of year. I wore this top almost everyday (over a light wool base layer) and it performed way above my expectations! Warm when it needed to be during rain and wind when worn under my light weight rain jacket and cool enough when the sun came out or when I went indoors. I will purchase another as a backup. Great job Simms!!!

The Best Review by Greg
Very warm but not bulky at all....a must have. The fit was just what an XL should be.

Great Value Review by Andrew
I am very pleased with this product. I ordered to use layering for winter fishing trips. I wear it so much I'm gonna have to order a few more. Looks nice enough to wear by itself and serves its purpose as a good mid layer top.

Fantastic! Review by LTC David
I have two complete sets of the Waderwick Tops and Bottoms, and in a word they are FANTASTIC! Very comfortable, well-made, and warm. Ideal for Winter layering and wear alone when it's just cool. I can tell they will last a long time. Any chance of getting them in a dark green???

Best hevy weight base layer the $ Review by William
These are workhorse expedition weight tops for a good price. Warm enough for winter layering and comfortable on cool summer nights outdoors. Last forever and look good.
