REI’s New Approach to Sizing, Design Raises Bar for Outdoor Industry Inclusion

The Seattle-based outdoor outfitter has adopted one of the industry’s widest sizing ranges, which has knock-on benefits as it works towards its own set of environmental and social goals.

If you step into any of REI Co-op’s 181 US locations this fall, you’re bound to see a broader range of sizing across several technical categories — in a first for an industry that’s short on, well, short sizes and has largely stuck to a model that mostly caters to “typical” bodies and builds.

“(Early on), we took a pretty big bet on sales and inventory investment; and now we’re starting to see both of those turn,” REI divisional VP of merchandising April Zito told Sustainable Brands® (SB).

In 2018, REI released an initial batch of a broader range of sizes in response to customer feedback — it began a multi-year journey to figure out how to build a product structure that better supported a wider range of bodies while also eliminating excess and increasing efficiencies. A big milestone was in 2021, when the co-op analyzed more than 150,000 data points from consulting partner Alvanon to conceptualize what the size and fit of this larger range would look like. It’s not a finished science; but today, a customer can walk into an REI store and find no less than ten different sizes in popular apparel items (such as jackets) and nine different options in sleeping bags.

“Hike, camp and snow are where we spend a lot of time creating the right product assortment,” Zito adds.

REI carries more than 1,400 brands in addition to its own; and all of those brands must adhere to a lengthy list of Product Impact Standards — which, among other things, detail sizing and accessibility requirements.

Nani Vishwanath — senior program manager for racial equity, diversity and inclusion (REDI) — told SB REI understands that not all brands can instantly adapt to these new requirements in size, scale, etc; but some of the company’s findings are open source. (A co-op spokesperson added that REI is happy to share insights on its own-brand approach, but companies should base their research on their specific brand’s fit and size standards.)

REI holds workshops where brands can learn some of this knowledge and trade best practices. They’re also important for communicating updates, such as REI’s upcoming requirement for headwear and helmet manufacturers to introduce products that support high-volume and textured hair. As Vishwanath recently shared during a panel discussion at SB’24 San Diego, this is also in direct response to consumer feedback.

She added that the outdoor outfitter has expanded the conversation around gender and whether specific, gender-based sizing and releases are really the path forward — as gender-neutral clothing and shared dress across “men’s” and “women’s” clothing become more popular. In response, REI recently introduced Active Pursuits — its first non-gendered apparel collection.

Furthering the co-op’s sustainability goals

Like most outdoor and outdoor-adjacent companies, REI has a set of goals related to carbon reduction, waste reduction and other key climate-action targets.

Waste reduction is where Zito sees the most potential in an inclusive sizing line. Creating a broader size range of clothes that consumers will actually buy leads to less stock and waste on the shelf — and perhaps will encourage consumers to choose a more durable, activity-specific item versus heading outdoors with something that’s not built to withstand those conditions.

“We were not 100 percent efficient when we launched, but we’re at a new place now (with more efficiency),” she says.

Traditionally, sizes XXL and above would have an extra cost — due to the thinking that they required more materials or special production lines. But the co-op says last year it achieved price parity across all its brands and products — regardless of size — which bodes well broader industry adoption of more inclusive sizing*.*

According to Zito, Fall 2025 products will look similar to this season. REI will invest in color and inventory with a larger focus on outdoor technical products compared to the broader lifestyle category, which has dominated the outdoor apparel space for the last several years.

“Not every brand has the capability to service all sizes, and we understand that,” Zito says, “but what we don’t want to do is put the fit out there that isn’t right.”
