Golf Digest just published a piece on heat therapy for back pain, soreness, and mobility—and for anyone who has spent years chasing relief, the takeaway reads like common sense: heat helps, but only when it is the right kind of heat.

Why most heat products fall short

Reach for a standard heating pad and you will feel warmth almost instantly. The problem is where that warmth stays. Most heat products only reach the tissue near the surface of your skin. It feels good in the moment, but the heat rarely travels to the deeper muscle and connective tissue around your lower back—the areas that actually drive stiffness and limited mobility. Warmth you can feel is not the same as warmth that gets where it needs to go.

What makes Far Infrared different

Far Infrared (FIR) works differently. Instead of heating only the surface, it is a longer-wavelength energy that your body absorbs more deeply. The technology traces back to NASA research in the 1960s and has been studied since for its role in supporting circulation and recovery. That deeper, more even warmth is exactly what Golf Digest's team pointed to—and why the L1 earned a mention as a practical way to put that heat where you actually need it.

Meet the L1

The L1 is a low-back wearable that pairs Far Infrared with topical heat in a design slim enough to wear discreetly under your clothes—on the course, at your desk, in the car, or before you are even out of bed. It is built to support mobility, warm-up, and everyday recovery without bulky pads, cords, or downtime.
