Flume 1/4 zip base layer

I am extremely pleased with the high quality fabric and construction. It is comfortable and provides the perfect layer I was looking for. I have worn it on multiple hikes and while mountain biking. It has held up to my rigorous standards. I highly recommend this product for all your outdoor needs. I am so very happy to support a local business.

Flume baselayer

Second baselayer, really appreciate that they come in tall sizes. The thumb holes are pretty helpful too when putting on a jacket or sweater so sleeves don't end up by your elbows.

Very soft, well constructed and warm. Nice fit that is not overly tight

New version/fabric is even better

I have the original version and the new one. Both great but I like to new fabric even better.
