Jack and Sage is expanding beyond premium destination apparel with the acquisition of 100% of the assets, intellectual property, and inventory of sustainable basics label Kastlfel. The deal gives the Colorado company a bigger foothold in the basics and logo wear market across national parks, ski resorts, and specialty outdoor retail.
The transaction also includes a strategic partnership with Kastlfel’s parent company, Ecocentric Brands, which will continue screen print decoration in Denver under the same water based sustainability standards. Financial terms were not disclosed.
A Push Beyond Destination Apparel
The acquisition marks a clear category expansion for Jack and Sage, which has built its name around elevated designs sold in destination driven retail settings. With Kastlfel now folded into the business, the company is moving more directly into sustainable tees, headwear, and knitwear while keeping its premium brand positioning intact.
That matters because logo wear has become more competitive, especially in outdoor and tourism driven channels where product quality and design are increasingly tied to brand perception. Adding a stronger basics platform gives Jack and Sage more room to serve partners that want both custom design and a broader assortment.
Sustainability Sits at the Center of the Deal
Kastlfel products are made entirely from sustainable materials, including organic cotton, recycled cotton, and recycled polyester. The company also says every factory and production facility is certified to global standards covering environmental processes, chemical management, and ethical labor practices.
Alex Biegler, Founder and Chief Executive Officer of Jack and Sage, said, “This acquisition is a meaningful investment into sustainability and product expansion. Kastlfel has built a best in class reputation for responsible manufacturing and trusted relationships with world class outdoor retailers. By integrating their platform into Jack and Sage, we’re able to expand into the sustainable basics market while staying true to our elevated design DNA.”
The emphasis on verified sustainability also carries through in how the combined company plans to sell the line. Marc Conner, Chief Operating Officer, said, “It’s not enough to simply claim sustainable materials. Consumers want proof. Third party certifications like GRS and OCS verify that our finished products contain the sustainable fibers we start with. Every step of the process is certified and transparent.”
A Bigger Product Range for Outdoor Retail
The combination gives Jack and Sage a fuller offer across kids’, women’s, and men’s apparel and accessories, along with premium custom artwork, low minimum custom programs, and immediate access to dozens of additional products. Over the next 12–24 months, the assortment is expected to expand from tees into hoodies, crew necks, beanies, and caps.
Both companies are headquartered in Denver, and the combined business expects growth in hiring across design, production, and wholesale operations over the next several years. That local overlap could help the integration move faster while keeping manufacturing and decoration close to the company’s existing base.
Why It Matters
For outdoor retail, the acquisition reflects a broader shift toward premium logo wear that does more than fill a souvenir rack. Retailers in national parks, ski resorts, and destination stores increasingly want product that combines design, storytelling, and sustainability in a more polished way.
For Jack and Sage, the deal is a scale move with a sharper sustainability angle. Instead of simply widening its assortment, the company is using Kastlfel to deepen its credibility in responsible manufacturing while building a bigger platform for growth in outdoor and destination retail.
