Why High-Growth Brands (Gymshark, Skims) are Returning to Structural Corrugated

 

Scaling Past the Poly-Mailer: Why High-Growth Brands (Gymshark, Skims) are Returning to Structural Corrugated

Hey, I’m Mark. If you’ve been watching the DTC space closely, you’ve probably noticed an interesting trend happening in 2026: many fast-growing apparel brands are quietly moving away from lightweight poly-mailers and going back to proper structural corrugated boxes.

It might sound like a small change, but it’s actually a big signal of brand maturity. Today, I want to explore why brands like Gymshark and Skims are making this shift, and what it means for the rest of us.

The Problem with Poly-Mailers Most Brands Discover Too Late

Poly-mailers were a revolution for speed and low shipping costs. They’re lightweight, cheap, and easy to stuff in a fulfillment center. But many high-growth brands are now realizing the downside: crushed garments.

When premium activewear, shapewear, or hoodies arrive looking wrinkled, creased, or flattened, customers feel disappointed. That disappointment often turns into returns. Higher return rates don’t just hurt your margins — they also damage brand perception and customer loyalty.

Gymshark and Skims have both grown into household names by delivering a strong unboxing experience. As their order volumes scaled, they started seeing the same pattern: flexible plastic packaging was saving money on shipping but costing them in returns and brand equity. The solution? Going back to rigid, protective corrugated boxes.

Why Structural Corrugated Boxes Are Making a Comeback

Structural corrugated packaging offers several clear advantages that poly-mailers simply can’t match:

• Better protection against crushing and damage during transit
• A premium unboxing experience that matches the quality of the garments inside
• More space for branding, storytelling, and now even digital traceability features (like QR codes or RFID)
• Improved volumetric weight efficiency when designed correctly

This transition from flexible to rigid packaging is a milestone in brand maturity. It shows that a brand has moved beyond just chasing the lowest possible shipping cost and is now focused on long-term customer satisfaction and operational intelligence.

How Leading Brands Are Approaching This Shift

This isn’t just a Gymshark and Skims story. Other big players are making similar moves in their own ways:

• Zara is redesigning its entire fulfillment architecture for 2026, partly to fight high return rates by improving packaging protection and efficiency. You can read the details in my post: The 'Serial Returner' Crisis: Why Zara is Redesigning its Fulfillment Architecture for 2026
• In the luxury segment, brands like Loro Piana and The Row have always understood the power of tactile packaging. Their focus on texture and premium feel is now being combined with smarter structural design.

• On the sustainability front, Patagonia continues to push the industry forward with its 2026 Material Recovery Framework, emphasizing mono-material supply chains that work beautifully with recyclable corrugated structures.

• And as transparency becomes more important, the outer box is turning into a key data carrier. I explore this trend deeply in the pillar post: How Transparency and Digital Traceability are Shaping Secondary Packaging (the main hub of this content series).

Making the Switch Without Massive Overhead

One of the biggest barriers for growing brands used to be the high cost and large minimum orders required for custom corrugated boxes. That’s no longer the case.
