Buying Guide

Check the UPF rating

Look for garments labeled UPF 50+ to ensure fabric blocks the majority of UV radiation during prolonged sun exposure

Prioritize moisture-wicking fabrics

Fast-drying, breathable synthetics help move sweat away from skin to prevent chafing and keep you cooler on runs

Consider fit and mobility

Choose a snug but non-restrictive fit with four-way stretch to allow full arm swing and comfortable layering under outerwear

Evaluate sleeve length and coverage

Long-sleeve designs offer maximum sun coverage for morning or midday runs; sleeve cuffs and seams should be flat to reduce irritation

Assess value vs. durability

Compare construction and fabric weight against price—durable flatlock seams and colorfast treatment extend usable life and justify higher cost
