From the store
Our lightest PAKAFILL® outerwear yet with a weight-to-warmth ratio rivaling any competitor, the versatile Mayu Ultralight Collection brings easy and uncompromising warmth to all your travel and adventure plans. With the power of traceable alpaca fiber insulation, this packable and lightweight men's puffer vest weighs a mere 7.1 ounces and can compress into its own interior chest pocket (making it a great camping or travel pillow). The recycled nylon shell is water-resistant and wind-resistant, with a tall collar for extra protection where you want it most. Minimal construction keeps the style durable and fully functional without adding bulk or drag, with intentional details like perfectly placed zip pockets with glove-friendly pulls. This easy-to-layer and sustainable puffer vest is more than a must-have, it’s a can-not-live-without.
