Since launching in 2018, Hermanos Koumori has built its reputation on a simple but hard-to-execute premise: running gear that doesn’t have to choose between performance and identity.
The Mexico City brand—founded by Alex Leon and Alex Sandler and rooted in pre-Hispanic mythology and Mesoamerican storytelling—has earned collaborations with Adidas and a global following without losing the cultural specificity that makes it interesting. The Spring 26 capsule is the latest expression of that balance.
The collection covers tops, singlets, hoodies, shorts, and shirts in an earthy palette with minimal branding and technical construction where it counts.
Some collection highlights include:
Dual Pace Stride T-Shirt. A long-sleeve regular-fit tee in washed Winter Moss cotton.. It reads as a recovery layer, something to wear post-run or between sessions .
Koumori Phase Hoodie. A boxy cotton hoodie in Rain Drum with a green-and-white graphic on the front, kangaroo pocket, and relaxed hood. It’s the kind of piece that bridges the gap between warm-up layer and off-day wear without looking like either.
Training Singlet. This is the technical side of the collection in full effect. A perforated technical-blend singlet with deep-cut armholes, 4-way stretch, quick-dry, and heat-transfer branding front and back. Designed for training sessions and moderate distances..
SS Competition T-Shirt. A lightweight, quick-dry performance tee in a regular cut with the same heat-transfer graphic treatment as the singlet. Built for high-intensity work and race days without sacrificing the clean silhouette.

Camp Shirt. A boxy, button-front shirt in a breathable stretch fabric with a hidden zip pocket and minimal HK branding. It has a technical construction beneath a relaxed exterior, the kind of shirt that works just as well on a travel day as on a rest day.
