300-mile Saturday loop, sun to drizzle. No cling, no stink, no sunburn. I retired my old base layers after this.
Softer than your favorite tee, best possible sun protection, and keeps you cool under your jacket.
4.2 oz fabric glides under leather, mesh, or textile—no bulk, no shoulder bind. Freedom to reach the bars and check blind spots without your shirt fighting you.
Pavement glare and mid-day UV sneak through vents and cuffs. Helios blocks it with UPF 50—10× the protection of cotton—so your neck, arms, and back don’t pay for the miles.
From helmet sweat to surprise road spray, Helios wicks and dries fast so you don’t sit clammy in the saddle. Anti-microbial tech keeps post-ride coffee stops… social.
Dawn chill to noon heat, the hidden mesh panels breathe when temps rise and layer cleanly when they drop. Works under your jacket in spring/fall and solo at fuel stops.
Colorfast, reinforced seams, and easy care after long rides. Wear it on real miles for 99 days—if it’s not your go-to base layer, send it back.
