LOOPWHEELER and LOWERCASE Bring Back Sweatshirt History’s Strangest Construction

A two piece hood, sewn on rather than knitted in, is heading back into the LOOPWHEELER x LOWERCASE rotation for fall and winter 2026.

Most hoodies are cut as one piece. The body and the hood come off the same pattern, sewn from the same bolt of fleece, and nobody thinks twice about it. The after hood does the opposite. It started as a plain crewneck sweatshirt, the kind American gyms and mills were turning out through the 1930s, and then a separate hood got tacked on afterward, almost as an accessory rather than a structure feature. The name describes exactly what happened: the hood came after.

 

Vintage examples of the style show up occasional at archive-grade dealers and in collector circles, usually two toned, usual with a kangaroo pocket, and usually treated as a curiosity rather than a wardrobe staple, since so few survived in wearable condition. Collectors and dealers who specialize in the category tend to source pieces from estate sales and old athletic outfitters rather than general vintage bins, since the after hood was never produced in the volume that plain crewnecks were. Survive examples often show the mismatched wear pattern that gives the construction away: a body fade and soften from decades of use, paired with a hood that frays different because it was sewn from a separate, sometimes slight different weight of jersey.

The construction fell out of mainstream production once integrated hood patterns became standard and faster to manufacture, but it never fully disappeared. A handful of Japanese heritage labels, among them Warehouse and Co., Cushman, and Samurai Jeans, have kept versions of it in rotation for years, treating it the way they treat selvedge denim: a period correct detail worth preserving even when it is not the most efficient way to make a garment. Those labels typically frame the after hood as a reproduction of a specific archival piece, down to the stitch count and the placement of the kangaroo pocket, which has turned the category into a small but active corner of Japan’s broader heritage workwear scene, sitting alongside raw denim, chain stitch embroidery, and shuttle loomed flannel as details collectors look for by name.

LOOPWHEELER built its entire identity around one piece of aging machinery. The company knits its sweatshirt fabric on loopwheel machines, a type of circular knitting frame that was largely phased out of Japanese textile mills once high speed knitting equipment took over in the 1970s. A loopwheel machine can only produce about a meter of fabric an hour, working the yarn through without pulling or extending it, which leaves the resulting jersey looser, thicker, and less prone to distortion over repeated washing than fabric knitted at modern speeds. LOOPWHEELER’s founders set out, by their own description, to make the most authentic sweatshirt in the world, and the brand has spent more than two decades since 1999 sourcing what remains of Japan’s loopwheel machine stock to keep that fabric in production.

The brand runs its flagship out of a shh corner of Sendagaya, a few minutes from the Shibuya crowds, where a loopwheel machine still operates in view of customers. That kind of visible manufacturing has become part of the draw. People who buy LOOPWHEELER product are, in large part, buy into the process as much as the finished sweatshirt, and the brand has leaned into that by publish detail notes on yarn counts, knit density, and machine provenance across its collections. LOOPWHEELER also runs stores in Osaka and Fukuoka, each keeping the same emphasis on view process over polish retail show, and the brand’s own newsletters regular walk customers through the specific of a given season’s fabric develop rather than treating those details as trade secrets.

That transparency has made LOOPWHEELER a fixture of a specific type of collaboration, the kind where a partner brand supplies a concept and LOOPWHEELER supplies the fabric science. Over the past several years the company has worked with Champion on a relaxed silhouette sweatshirt designed by N. Hoolywood’s Daisuke Obana, with White Mountaineering on crewnecks and cardigans built from a lighter loopback jersey, and with Graphpaper on a series of oversized, drape heavy sweats that reworked the brand’s classic pattern into something closer to outerwear. Each of those projects treats the loopwheel fabric itself as the constant, with the partner brand’s identity expressed mostly through fit and silhouette rather than through logos or graphics, a house style LOOPWHEELER has kept remarkably consistent across more than two decades of outside collision.

LOWERCASE is the solo label and consulting name of Yoshikage Kajiwara, a former creative director at Beams who has spent the years since building a reputation as one of Tokyo’s earliest cross industry convincer. Kajiwara’s client list stretches from Nike and Motorola to Disney, Lego, Seiko, and Yoshida’s Porter line, and the through line across nearly all of it is a habit of pairing a manufacturer known for one specific craft with a concept most of that manufacturer’s peers would never attempt. His work with LOOPWHEELER falls into that pattern directly. Rather than treating the loopwheel sweatshirt as a finished product to simply rebrand, Kajiwara has spent years pushing the fabric itself into new territory, including a wool blend loopback jersey the two sides nicknamed Woolwheeler, which now returns as a seasonal fixture.

The LOOPWHEELER x LOWERCASE line has run through a rotating cast of Japanese retail partners over the years, most consistently Edifice and Urban Research Doors, with occasional appearances at United Arrows and, in a three way project with stylist and curator Poggy, a run of vintage inspired pullover hoodies that borrowed color blocking straight from mid century American sportswear. That project, credited to all three names, leaned on a double faced fabric construction and a bulky, deliberately oversized hood, with a companion illustration commissioned from artist FACE for its packaging, a detail typical of how Kajiwara tends to layer a collaboration with additional creative names rather than keeping it strictly bilateral.

The two piece hood construction is not new to that partnership either. Earlier Edifice exclusive releases under the LOOPWHEELER for LOWERCASE name have used loose fit pullover hoodies with a similarly separated hood panel, and the line’s wool blend Woolwheeler fabric, first introduced as a limited seasonal offering, became popular enough that LOOPWHEELER brought it back the following year after early demand outpaced the initial run. That pattern, an experimental fabric or construction tested through the LOWERCASE partnership before finding a wider audience, has repeated often enough that industry watchers tend to treat the collaboration less as a one off drop calendar and more as an ongoing research line for the brand. The fall 2026 after hood piece reads as a continuation of that same approach: an idea the two sides have circled before, refined again for a new season rather than introduced from scratch.

The item surfacing for fall and winter 2026 carries the name Exclusive After-Hood Sweatshirt, position as a LOOPWHEELER for LOWERCASE special order piece with an early October rel window. That time and name come from a Japan market release notice, the kind of early trade announce that regular precedes a full product page by weeks in the Japanese connectiom calendar. What the notice does not yet include is a confirmed retailer, a price, or a full fabric and colorway breakdown, the sort of detail that typical follows once a partner store puts up its own list.

Given the connection’s history, an Edifice or Urban Research Doors exclusive would fit the establish pattern, and a loopback or wool blend fabric consistent with past LOOPWHEELER for LOWERCASE hooded pieces would be a reasonable expectation rather than a confirm spec. None of that is stated outright yet, so it is worth treating as context rather than fact until a retailer listing lands. What can be said with more confidence is the construction itself: an after hood, sewn on separate from the sweatshirt body, which puts this release in direct conversation with the vintage pieces LOOPWHEELER has spent its whole existence trying to match.

The early October timing is also worth noting on its own. LOOPWHEELER’s Japan market collide have historic clustered rel around two windows, a late summer push tied to the brand’s own pre order events and a fall entry point aimed at the start of sweater weather, and an early October date sits squarely in that second window. Retailers carrying loopback and wool blend sweatshirts typically want inventory on the floor before the first real cold snap hits Tokyo, which usually arrives in mid to late October, giving a several week runway between an early month rel and the point where customers actual start reach for heavier layers. That timing pattern is consistent across the brand’s past few fall collision, even though it says nothing specific about this particular piece’s price or where it will be sold.

There is a reason heritage focused Japanese labels keep returning to the after hood instead of letting it stay a museum piece. The construction produces a slightly awkward, slight bulky hood attach that a modern integrate pattern was specific design to eliminate, and that awkwardness has become the point. In a market saturated with clean, engineered hoodie patterns, a garment that view shows its seams and its process reads as more consider, not less. It is the same instinct that keeps raw denim, hand knit gauges, and view men in circle among people who could easily buy something smoother, a preference for garments that read as made rather than manufactured.

For LOOPWHEELER specifically, the after hood also lines up with the brand’s founding premise. A company built around slow, low output knitting machinery has an obvious affinity for a hood construction that trades efficiency for a specific, period accurate look. The two ideas share the same underlying logic: both prioritize a particular, historically grounded result over the fastest or cheapest way to arrive at a finished hoodie. That alignment is part of why the after hood has surfaced periodically across the LOOPWHEELER for LOWERCASE line rather than appearing once and disappearing, and why it tends to draw a different customer than the brand’s cleaner, more minimal pullovers do.

Pairing that construction with Kajiwara’s habit of pushing familiar categories somewhere unexpected gives the release a clearer identity than a straightforward hoodie drop would carry on its own, even before a price or retailer is confirmed. Kajiwara’s track record with LOOPWHEELER, stretching from the original Woolwheeler fabric through the Poggy connection double faced construction, suggests the fall 2026 piece is unlikely to be a simple reissue of a past design, even though the current release notice does not yet spell out what specifically has changed. Whether it lands at Edifice, Urban Research Doors, or somewhere new, the early October timing puts it right at the start of the season when loopback and wool blend sweatshirts start doing their most, and gives shoppers a full season to decide either a construction built to look slightly wrong on purpose belongs in their fall rotation.
