What Our Gearhead(R) Experts Are Saying: "This is my go-to multisport baselayer. The Air-Con merino keeps me warm when it's cold and cool when I start pushing hard. The mesh back panel dumps heat perfectly under a pack, and the slim fit layers really well. It's one of those pieces you end up wearing for everything-running, hiking, biking, even travel." We layer up with the Mons Royale Temple Merino Long-Sleeve Shirt when the day calls for lightweight comfort, dependable breathability, and performance that adapts to every adventure. Made with Merino Air-Con 140, this top delivers natural climate control-keeping us warm when chilly winds pick up and cool when our pace increases on steep climbs or fast transitions. Soft, breathable, and naturally odor-resistant, it keeps us comfortable during high-output missions and multi-day travel alike. A merino mesh back panel provides extra ventilation where we need it most, making this baselayer ideal under packs or outer shells. Raglan sleeves boost mobility for everything from trail runs to mountain bike sessions, while thumb loops and a dropped tail hem add practical coverage and stay-put comfort. Lightweight yet capable across all seasons, the Temple LS is built to move with us through every pursuit.
