Aruta: Built to Alter
We’re a Singapore-designed climbing brand creating gear for the ASEAN fit—wider forefoot, secure/narrow heel—so comfort and precision show up from day one.
Athlete-tested, data-led, and community-built, Aruta focuses on real performance in humid gyms and slick stone. Fewer products, higher standards. Change what needs changing—climb the rest.

Kumo Chalk
KUMO is Aruta’s chalk line—built for ASEAN humidity and modern movement. Whether you prefer silky, ultra-fine coverage or the tactile control of breakable chunks plus powder, KUMO keeps friction high and dust low so you can focus on flow, not moisture. Consistent from bag to bag, additive-free, and packaged to refill.
How to choose (quick guide)
-
Pick Powder if you want the fastest, cleanest re-chalks and ultra-even coverage.
-
Pick Mix if you like tactile grip with fewer full re-chalks during longer burns.
