Description

The L1 | 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.

Awesome layer

I wear these all the time. The power grid material is pretty sweet. I haven’t had a pair of long Johns that breath this well before. Definitely recommend. They’re great for higher output activities too!

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.

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.

A1 - Aether Long John

Super versatile piece of clothing. It’s thin enough to layer under just about anything, including athletic clothing, and provides an exceptional amount of additional warmth. The XL Tall fits my 36” inseam (a rare thing) and fits close. It also fits nicely under the Krios Long John for an extremely warm set-up. It’s now an essential part of my fall/winter layering system for living in Montana.

Perfect base layer for activity in cold to mild weather

Had a chance to test these a few times now. Training in the mountains with temperatures ranging from about 20F to 45F. Climbing rocks and trekking with about 40-50lbs of kit. Never got too hot or too cold. Sweat began wicking immediately. Craftsmanship makes it well worth the price and best of all...Made in USA.

A1 Aether Long John - the best

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.

Holy cow, these are warm!

These are a great long john's. They are much warmer than the cottons type. And the inner, gridded lining is quite soft.
I can promise that you'll hardly take these off, outdoors or indoors, during the cold months.
