The best thing you can normally say about a sweatshirt is that its nice and comfortable. And the 100 Year Sweatshirt does that bit brilliantly its super stretchy, breathable, and lined with ultra-soft fleece. But its also windproof, abrasion resistant, water repellent, fire resistant, and can withstand temperatures 4x hotter than the sun. So its fair to say its an upgrade.
The sweatshirt combines 4 different layers of technology. The inside is made from an incredibly dense fleece thats 4x more windproof than a regular fleece, while the outside of the fabric is a blend of modacrylic and aramid fibres for fire resistance. On top of that there are two coatings. One is a fluorocarbon-free treatment that helps it shed rain and snow. The other fuses high strength polymers directly into the fibres to make the sweatshirt highly abrasion resistant.
