In August 2022, REI Co-op product developer Lauren Bowman requested tons of of drugs testers of all styles and sizes to hunker down in sleeping bag samples. Bowman needed to take measurements whereas precise individuals used the luggage to pinpoint optimum match for real-world backpackers. So whereas testers performed playing cards and skim books within the bedding, she famous the place the baffles pinched, gapped, sagged and bulged. The aim: to create better-fitting luggage.
These match periods have been a part of a complete REI Co-op initiative that seemed critically and exhaustively at how properly this piece of drugs served the rising demographic that wishes to spend time outdoor. Inclusivity motivated the reevaluation, explains Bowman.
Analysis and rigorous testing ensued, in the end informing the design of 9 new genderless sizes for 3 of the co-op’s most technical sleeping luggage—the Magma 15, Magma 30 and Zephyr 25—in a giant transfer away from restricted sizing primarily based on a binary gender mannequin.
“If we are saying the outside is for all, how will we facilitate that by really having luggage that individuals can sleep in?” she asks.
The Sleeping Baggage
Sleeping bag sizing hasn’t modified a lot since their 1876 invention by the redundantly named Welshman Sir Pryce Pryce-Jones (who additionally launched the first-ever mail-order catalog enterprise). For many years, REI Co-op has principally offered its house-brand sleeping luggage in two sizes—common and lengthy—for women and men. Whereas these luggage labored for some individuals, shorter of us ended up with pointless house that value them weight and heat (the additional room compromises thermal effectivity). And since product girths didn’t differ, slender of us tolerated too-big luggage whereas bigger customers weren’t accommodated in any respect.
“We have been listening to from some clients that they have been annoyed looking for the precise match,” explains Bridget Stephas, REI Co-op product designer. The need to create higher sizing led REI to widespread testing and match periods and, finally, the debut of latest sizes for 3 current REI Co-op sleeping luggage.
The Magma 15, Magma 30 and Zephyr 25 are actually every supplied in 9 sizes as an alternative of 4, starting from brief slender to lengthy extensive, and are now not labeled by gender. Importantly, they preserve the identical technical options backpackers count on from these long-standing sleeping luggage, like a water resistant end, considerate pockets and a roomy footbox.
“We need to serve those who haven’t been well-served [by sleeping bags] up to now,” Meade mentioned.
The Sizes
Decided to take a contemporary take a look at a basic piece of backpacking gear, REI designers constructed on the model’s 85 years of expertise. “We needed to make no assumptions,” explains Bowman, the product developer who performed a driving function within the reevaluation.
REI commissioned a consulting firm that makes a speciality of attire match to conduct a large-scale examine of People’ present our bodies. Topics included 150,000 individuals representing various styles and sizes, starting from 25 to 40 years previous. “We obtained this large wealth of body-scan knowledge,” explains Bowman. The outcomes revealed two discoveries.
One was that the present line of REI Co-op premium, backpacking-oriented sleeping luggage solely supplied an optimum match for simply over half of the individuals scanned within the examine. Some couldn’t use them in any respect as a result of they have been too slender.
“To get most thermal effectivity out of a backpacking bag, you desire a close-to-body match that enables some air circulation however not an excessive amount of,” explains Jon Almquist, REI Co-op product supervisor. “That method, you exploit the total advantage of the high-quality down we put within the bag.”

The examine knowledge additionally indicated that match developments didn’t differ a lot between female and male our bodies. “General, males’s shoulders development a bit of wider, however the distinction is so small in relation to how free over the physique a sleeping bag matches that it turns into negligible,” Bowman says. Sleeping luggage aren’t like denims: Even the optimum, body-hugging minimize most well-liked by performance-minded backpackers is forgiving sufficient to skim over slight variations in physique form.
With the body-scan knowledge suggesting that gendered matches aren’t vital, the product creation staff thought-about temperature rankings, which usually differ for women and men. In accordance with take a look at protocols utilized by the International Organization for Standards (ISO), heated mannequins are positioned inside a sleeping bag to guage warmth loss. The calculated outcomes produce numerous temperature rankings: The bag’s T-Restrict ranking signifies the temperature all the way down to which a heat sleeper (assumed to be male) will really feel comfy; the T-Consolation ranking denotes the consolation vary for chilly sleepers (assumed to be feminine). Girls’s luggage usually use the T-Consolation ranking, whereas males’s luggage show the T-Restrict quantity.
In accordance with take a look at protocols utilized by the Worldwide Group for Requirements (ISO), there are two completely different temperature rankings: one for chilly sleepers (T-Consolation) and one for heat sleepers (T-Restrict). Girls’s luggage typically use the T-Consolation ranking, whereas males’s luggage show the T-Restrict quantity.
But match additionally influences insulation, notes Bowman. “A body-hugging match is warmest, whereas a semifitted bag permits extra room for numerous sleep positions however loses some thermal effectivity,” she explains. As an example, the relaxed form of an oblong car-camping bag loses probably the most warmth however emphasizes comfy motion.
The product creation staff due to this fact determined to concentrate on match, no matter gender. Beginning in spring 2024, the Magma 15 and Magma 30 (the co-op’s performance-oriented backpacking luggage full of 850-fill, water resistant down) are available in 9 dimensions every, from brief slender to lengthy extensive. The synthetic-fill Zephyr 25 additionally is available in 9 sizes. Honed by meticulous match periods, the brand new sizing choices present an optimum match for almost all the our bodies scanned within the complete examine.
The luggage nonetheless bear ISO temperature testing, solely now their ranking represents the midpoint between the T-Restrict and T-Consolation figures (that are additionally printed on the baggage for customers who need to see the total vary). Thus, the brand new luggage are barely hotter than earlier males’s and unisex fashions.
“We didn’t simply make a males’s bag in 9 sizes,” says Bowman. “Actually, they’re for everybody, of all physique sorts and completely different sizes.” Girls’s knowledge was simply as influential within the luggage’ creation as males’s enter—a key distinction from earlier merchandise made 40 years in the past, explains Bowman. “We landed on non-gendered luggage by means of analysis.”
The Outcomes
The unified temperature rankings simplify the purchasing course of for women and men. In addition they enable backpackers to decide on the bag that fits their physique form and temperature wants no matter gender: Males who sleep chilly, for instance, now not have to browse the ladies’s choices to get the optimum product. And nonbinary backpackers now not have to start out the purchasing course of by selecting amongst binary gender labels.
As for the largest profit to the brand new genderless dimension vary? Extra backpackers can discover their finest sleeping-bag match and luxuriate in evening’s sleep outdoors.
