A Classic Loved for Over 80 Years! Here’s Why J.E. Morgan’s Thermals Are the Top Choice

Founded in 1945 in Pennsylvania, USA, J.E. Morgan earned a reputation for its thermal wear that perfectly balanced durability and comfort. The brand even has a history of supplying underwear to sports teams and the U.S. military. The signature of J.E. Morgan is its waffle knit. In an era where countless high-tech performance fabrics are available, we delve into the enduring appeal of this classic thermal material.

"Thanks to the popularity of American casual style in the 1980s, the name J.E. Morgan became synonymous with thermals in Japan."

Although production in the U.S. eventually ceased, the brand’s high performance and enduring popularity led to a mission to revive the "サーマルパックT". Researchers studied deadstock and vintage pieces to reproduce the materials, fit, construction, and even the packaging as faithfully as possible. The result is the J.E. Morgan we know today.

The Waffle Weave: A Masterclass in Breathability and Insulation

The brand’s signature waffle-weave fabric might look like a simple, low-tech material at first glance. However, it conceals a brilliant design logic honed over many years.

The most significant feature of the waffle knit is that the fabric itself is structured to trap a layer of air. Its textured, grid-like pattern minimizes contact with the skin. This creates a micro-gap between your body and the garment, which acts as a passive layer of insulation.

"The knit's three-dimensional texture allows it to create an air layer all by itself. When you wear a size that fits snugly, that air layer is warmed by your body heat, boosting its insulating properties."

Unlike trendy high-performance fabrics that use moisture-wicking or heat-generating technology, J.E. Morgan’s thermals rely on the knit structure and the wearer's own body heat to provide warmth.

"What's more, the tiny gaps between the yarns make the fabric highly breathable, which helps prevent you from overheating."

This dual ability to trap heat when it's cold and release excess heat when it gets warm makes it a perfect fit for modern city life, where we constantly move between different temperatures and find it hard to regulate our body temperature.

Evolving for the Modern Era While Honoring Its History

The fabric's textured surface also provides excellent stretch, allowing it to conform gently to the body for a soft, comfortable feel.

"Beyond our loyal fans who appreciate it as a timeless American classic, we're seeing more and more newcomers discover J.E. Morgan. They fall in love with the lightweight, warm, and incredibly comfortable feel of the waffle material and become dedicated users."

While J.E. Morgan is well-known for its 'Pack T's,' recently the brand has been expanding its lineup with a wide variety of colors and designs that showcase the material's excellent qualities.

"Our thermals used to be seen primarily as underwear, but recently, our thicker items have become popular. They can be worn casually like a sweatshirt or styled elegantly like a sweater.

The waffle knit has such a distinct texture that it also works great as a layering piece. I recommend letting it peek out from under a shirt or jacket."

Even the classic Pack T's have been updated for the modern era.

"We've stayed true to the brand's philosophy of creating insulating innerwear, so we've kept the traditional longer hem. However, we have repeatedly re-evaluated the silhouette to find the perfect fit for a base layer. We've adjusted the sizing of various parts multiple times from the original imported design.

For our heavier-weight items, we use a blend of 80% cotton and 20% polyester to help prevent the stretching and loss of shape that can be typical of waffle knits. Our flagship item, the "Big Waffle Crewneck", is designed with a slimmer silhouette than standard sizing for a cleaner, more streamlined look."

While preserving its long-loved thermal wear, J.E. Morgan continues to evolve into a comprehensive lifestyle brand, offering casual apparel and accessories.

"We still get questions from customers asking, 'Don't you make them in the USA anymore?' While it's become difficult to source the exact same fabric as we used to, we believe the waffle knit is a material that will endure. Just like jersey T-shirts and French terry sweatshirts, it provides excellent insulation without requiring any special processing or advanced spinning technology."

J.E. Morgan's thermal wear, beloved for over 80 years, is an indispensable item for the upcoming seasons of fluctuating temperatures. We invite you to experience for yourself the power of a material that has stood the test of time.
