F-LAGSTUF-F x AIR JAM 2026. Pre-order through 31 October, 23:59. Ships late October. Hi-STANDARD’s stadium date is 7 November.
F-LAGSTUF-F opened a reservation window on 7 September at 11:00 for goods made toward AIR JAM 2026. The live card on the official shop is SOX (xAIRJAM), style noted as a house sport-rib sock on the brand’s usual body. Cotton 56, acrylic 24, polyester 13, nylon 5, polyurethane 2. Listed at $12 USD on the English price line. Reservation runs to 31 October 2026, 23:59. Ship window: late October, subject to production. Cap on units. Mix a reservation piece with in-stock goods and the whole order waits for the later date.
That is the SKU that is on the page today. The brief said collaboration items, plural. Treat extra silhouettes as unposted until they sit next to the sock. Official festival merch is a different door: airjam-store.com, which already ran a five-day official-goods preorder in August and said the venue will not sell goods on the day.
Signal. What happened: Flagstuff posted AIR JAM 2026 collaboration product with a 31 October reservation close. Exact product: SOX (xAIRJAM), house rib sock, ship late October. When and where: preorder 7 September 11:00 to 31 October 23:59 JST, f-lagstuf-f.com. Festival: 7 November 2026, ZOZO Marine Stadium. Price: $12 USD on the sock card. Source: F-LAGSTUF-F product page. Why it matters: a Tokyo street label tying a sock to Hi-STANDARD’s first Air Jam in eight years, while the stadium itself will not have a merch tent. Earlier DRIFT: none on this capsule.

huh
Nobuyuki Murayama started F-LAGSTUF-F in Tokyo in 2014. Flag plus stuff. American 80s street cut through a Japanese block. The label lives on collabs as much as seasons: band art, film, other shops. The Air Jam sock is that habit pointed at a stadium date.
The product copy is short. Special collaboration item made toward AIR JAM 2026. Standard Flagstuff sock body. Sport rib. Material breakdown as above. No poem. Ship late October so the pair can exist before 7 November. If production slips, the page already asked for patience. Hit the unit cap and the window dies early.
$12 is a sock price, not a jacket price. That is useful. Air Jam official tees in the August store sat at ¥5,000 for a 2000 commemorative shirt. Flagstuff is selling a foot item that can sit under those tees without competing with the festival’s own rack.
Reservation rules are the Japanese shop rules everyone already knows and still trips on. Buy the sock with a regular hoodie and both wait. Buy two reservation styles with different ship dates and both wait for the later one. No split ship. Free shipping on the shop at 16,000 yen.
If more Air Jam sil join the sock before 31 October, they will use the same clock. Until they do, the collaboration in hand is a pair of ribs.

AIR JAM is Hi-STANDARD’s festival. First edition 1997, Odaiba, punk and skate in the same afternoon. 2000 put it in a stadium, Chiba Marine, the yard now called ZOZO Marine. 2011 came back as relief after the earthquake. 2016, 2018. Then eight years of quiet. On 11 March 2026, during the Screaming Newborn Baby Tour in Sendai, the band said 2026 was on. 7 November. Same stadium as 2000.
Eleven acts. Hi-STANDARD headlines. Japan: 10-FEET, ENTH, HEY-SMITH, HUSKING BEE, KUZIRA, MAN WITH A MISSION, The Cro-Magnons, Maximum the Hormone. United States: Lagwagon, Dance Hall Crashers (back after twenty-one years). Host: Hi-STANDARD. Planning: HS co.,ltd. Production: Live Nation H.I.P. Cooperation includes Pizza of Death.
Official goods ran 8 to 12 August on airjam-store.com. Artist collabs in that window too (10-FEET had its own). The important line from the festival account: no goods sale planned at the venue. If you want a shirt in the pit you order it in August or you wear what Flagstuff mailed in late October. That is why a sock with a 31 October close still has a job. It arrives in the week before the gates, not at a booth that does not exist.
Tickets went through PITPRESS lottery, then general sale in late August. Worldwide copy asked people to come to Japan. The festival is one Saturday. The sock is the object that can leave the Saturday.

scope
Flagstuff has already put Blur, Slipknot, The Pogues, Cowboy Bebop, EVISU on apparel. The method is licensed graphic on a house block: ringer tee, coach, cap, pant. Air Jam is closer to a date than a catalogue. The date is Hi-STANDARD’s. Pizza of Death is the label gravity around that band. Flagstuff is not the record company. It is the shop that made a sock for the reunion stadium.
Hi-STANDARD is the Japanese punk trio that made Air Jam a noun. Ken Yokoyama, Akihiro Nanba, Akira Tsuneoka. The 2000 stadium show is the origin myth this year’s venue choice is quoting. A 2026 sock cannot carry that myth. It can carry a mark into a shoe that will stand on the warning track.
fin
Do not confuse Flagstuff’s reservation with the official Air Jam store. Two URLs. Two calendars. One festival that refused a merch tent. That refusal is the production fact that makes a late-October sock rational.
Pre-order to 31 October, 23:59. Late October ship. 7 November at ZOZO Marine. Eleven bands. One listed Flagstuff SKU today. If the shop adds a tee before the clock stops, the same rules apply. If it does not, the collaboration is a rib sock with a festival name on a page that closes at the end of October.
