The A1 Aether Long John is a high-performance breathable, moisture wicking baselayer built from Polartec’s® super lightweight Power Grid™ fleece. The next-to-skin grid pattern is made up of air channels that help release excess body heat and perspiration. The smooth exterior of the fabric forces moisture to disperse and evaporate quickly. The grid construction also increases compressibility and reduces garment weight. Flat seam construction reduces bulk and irritation when layering. Wear the A1 Aether Long John as a next-to-skin layer for lightweight moisture management during active use.

Best long John bottoms I’ve used. Very thin but very very warm. Fabric and grid pattern also make it some of the most comfortable bottoms you’ll put on. I’ll be picking up a second pair for sure.
