Warmth Without Weight

Ask any traveler, backpacker, alpinist, or anyone crazy enough to measure their pack in grams - every piece of weight matters. Countless hours of design went into making the Mayu lighter than anything else on the market while always prioritizing ethical materials and sources, because we wanted to build a piece that had no tradeoffs.

• Extremely Lightweight: At around 7oz for the vest and 9oz for the jacket, it weighs next to nothing. That's less than most people's lattes and one less thing to worry about when getting your pack together. 
• Unbeatable Alpaca Warmth: PAKAFILL® insulation overperforms when you need it most, achieving a CLO value (the industry standard for measuring clothing warmth) of 1.6. Details like an interior cinch system at the jacket hem keep heat from escaping.  
• Recycled Materials: Built with a recycled nylon shell and lining without any intentionally added PFAS, it's wind and weather-resistant. Plus, it layers perfectly in case you need to slip it under a waterproof shell. 
• Built for Movement: Designed with set-in sleeves for easier movement and reach, along with two convenient front zip pockets that open with ease, even with gloves on. 
• Function Over Fluff: Small but intentional details like using a kissing welt zipper instead of a bulky storm flap and lightweight cord locks and zipper pulls cut down on weight without giving up durability. 
• Pocket Packable: Both the jacket and vest can be packed into the interior chest pocket, taking less space in your pack and making a great pillow for camping or travel.

To launch this new collection, we’ve partnered with hikers, travelers, and even paragliders to put Mayu to the test where weight matters most. Follow along at @paka to see their adventures this fall.

“The jacket was surprisingly just as warm as my 800 fill down jacket, while being more breathable as well. It didn’t restrict my movement, and I could hardly tell I was wearing it.”

~ Michael Niedrich, Paraglider

This isn't our first jacket to use our PAKAFILL® insulation (check out the Apu collection), and it certainly won't be our last. Its performance speaks volumes, and the science backs it up with PAKAFILL® testing warmer than any synthetic insulation. And more than that, it's sourced from free-roaming alpacas in the Andes, eliminating the cruel practices of goose feather down.

We recently received our very first patent for PAKAFILL®, which was an amazing moment in the history of our brand. Thank you to our community for supporting PAKAFILL® over the past couple years.

We can’t wait to hear what you think of the Mayu collection! Please leave us your thoughts in the reviews and tag us @paka in your Mayu adventures on social.
