Alto Light 3-in-1 HS Hooded Jacket – Men’s

What Our Gearhead® Experts Are Saying:

“This jacket is the definition of versatility. The waterproof shell keeps me dry on wet hikes, while the insulated liner adds just the right amount of warmth in colder conditions. I love that I can wear them separately or together depending on the weather. The underarm vents are a must for breathability, and the adjustable hood and cuffs help dial in the fit. It’s an all-season essential for any adventure.”
