Hans Global Textile
Creative Tech Textile, also known as Hans Global Textile, announced a newly developed fiber blend explicitly made for the United States market. The Taiwanese producer’s latest blend comprises 40 percent of its signature Seawool and 60 percent cotton, made intentionally to “balance cost-effectiveness with sustainability.”

Made from discarded oyster shells and recycled ocean plastics like PET bottles, the company’s proprietary, patented material offers odor resistance (compared to that of pure cotton garments) as well as thermal regulation, with oyster-shell powder working as a low-thermal conductor.
“Seawool is our ‘emerald from the ocean’—a sustainable material born from upcycled oyster shells and engineered for everyday comfort,” said Eddie Wang, founder and CEO of Hans Global Textile. “Our new 60-40 blend [shows] that circular textile innovation can scale globally to empower our U.S. customers while creating new possibilities for today’s consumers.”
The company reportedly repurposes some 500 tons of oyster shells a year, annually producing 2,500 tons of Seawool—what’s allegedly a 10th of the cost of down and 20th of the cost of high-grade wool.
Revoltech x Leica
German startup Revoltech has partnered with premium camera manufacturer Leica on a plant-based mechanical watch strap, made with LOVR: Revoltech’s circular material that stands for “leather-like-without-plastic-vegan-residue-based.”
“This is a meaningful moment for us,” said Lucas Fuhrmann, co-founder and CEO at Revoltech. “Leica represents timeless design and precision engineering. Seeing LOVR used in one of their products shows that new materials are ready for applications where quality and longevity matter.”
Made from European hemp and plant-based additives, LOVR contains no plastic, no polyurethane (PU) and no polyvinyl chloride (PVC). The strap was developed for Leica’s mechanical watches and produced in Hesse, where both companies are based; now integrated into Leica’s official accessories lineup, the strap is available online for $160.
Cotton Incorporated x Lisa Says Gah!
Cotton Incorporated and Lisa Says Gah! have launched the holiday announcement tees collection: a limited-edition capsule by the Californian cult-followed brand made with 100 percent cotton. The cheeky collaboration underscores one consumer commonality during the celebrating season: concerns over conflict.
“These tees give people a comfortable, breathable way to show up as themselves, and have a little fun doing it,” said Anne David, director of advertising, Cotton Incorporated. “There’s no better fabric for staying cool under pressure than cotton.”
According to the 2025 Cotton Incorporated Lifestyle Monitor Survey, 71 percent of consumers choose cotton when shopping for holiday gifts “because it’s comfortable,” while, tangentially, over half (56 percent) said they choose cotton “because it feels good.”
“The holidays can be a lot, so we wanted to design something that brings both levity and comfort,” said Lisa Bühler, founder of Lisa Says Gah. “This tee does both—a conversation starter and a diffuser, all wrapped in soft 100 percent cotton.”
Nearly nine in 10 (89 percent) of adult Americans shared feeling stressed out during the holidays, according to the results of a 2023 poll by the American Psychological Association; 58 percent cited spending too much or not having enough money to spend as primary stressors.
