Rab Syncrino Base T-Shirt

What Our Gearhead® Experts Are Saying:"I wore the Syncrino Base T-Shirt as a standalone layer on a warm approach and then as a baselayer once we hit altitude, and it handled both ends of the day without complaint. The merino keeps odor from building up over multi-day trips, and the synthetic blend dries noticeably faster than a pure wool tee after a sweaty push. At just over four ounces, it earns its place in the pack every time."The approach starts warm, and the summit feels like a different season entirely. What you wear against your skin has to work across that whole range, wicking hard on the climb and holding warmth when the wind picks up at the top. The Rab Syncrino Base T-Shirt is built for exactly that spread, blending merino wool with fast-drying synthetic fibers into a single lightweight fabric that adapts to whatever the mountain throws at you.Rab's Syncrino 125 fabric earns its place by doing two things at once. The merino component insulates, wicks moisture away from the skin, and naturally resists odor through multi-day pushes without needing a wash. The recycled polyester component adds durability, accelerates drying, and keeps the overall weight at just 4.1 ounces for a medium. Low-bulk seams sit comfortably against skin and layer cleanly under a midlayer or shell without bunching. Slim through the body without feeling restrictive, the Syncrino Base T-Shirt is the foundation that makes every layer above it work better.
