Intentionally designed and constructed to be highly packable.


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.

Base layer

I bought my son these for Christmas and he is currently visiting his brother in Alaska and they were absolutely amazing. By far the best base layer out there and well worth the money.


Comfortable, do a great job

Blew my expectations away!

I bought several items for the last hunting data of the year in WA state, and it was cold and rainy and wet and miserable - except the Beyond clothing thermals and rail layer were absolutely outstanding - small I say, BEYOND?! 😂

Really amazing performance and quality. Truly worthy of the name.


Is comfortable and light weight I am six foot three with a thirty three inch waist They are not too loose and plenty long
