Short Sleeve Layer: The Seamless Base Layer for Warmer Days

The Short Sleeve Layer is UNDR's seamless base layer built for warmer days and warmer climates, offering torso support and heat management without the additional coverage of a full vest or bodysuit.

Not every day calls for the same level of structure. A hot summer day, a warm-climate business trip, a golf round in July — these ask for support without the added warmth of more fabric. The Short Sleeve Layer is built for exactly that gap: real compression support through the torso and chest, in a construction that breathes.

What makes it seamless

Raglan shoulder construction removes the seam lines that typically run across the shoulder and upper arm on a standard T-shirt — the seams most likely to show as a ridge under a fitted dress shirt. The result is a layer that stays genuinely invisible under lighter summer fabrics, not just under a heavier suit jacket.

When to reach for it

Warmer months, warmer climates, or any day where the Support Vest's heavier structure would be more warmth than the day needs. It's not a lesser version of the vest — it's the right tool for a different kind of day, built with the same support principle in a lighter package.
