Yes. Every piece in this collection is sourced through authorized brand channels — Illadelph supplies retail accounts directly from its Philadelphia operations, and Mothership Glass tightly controls its apparel distribution out of Bellingham. Both brands are heavily counterfeited online; unauthorized prints typically use cheaper blanks (Gildan-grade), exhibit off-register printing (visible double-lines on the Illadelph script, off-center nebula on Mothership graphics), and skip the brand's standard interior labeling. Pieces from this collection carry correct labels, correct print registration, and were ordered direct from the brand.

Standard US adult sizing across both brands — sizes typically run from S through 2XL on the screen-print Illadelph tees and the Mothership Yellow Nebula. Available size run on a given listing depends on what's currently in stock at the time of order; if a size shows as out of stock on a specific tee, restocks happen on Illadelph's regular production cycle (the brand keeps the Signature and Camo Logo in continuous production) but Mothership pieces are tied to limited drops. Check each product listing for live size availability before ordering.

The screen-printed Illadelph tees (Signature, Camo Logo, Rasta) fit true to standard US adult sizing on a heavyweight cotton blank — closer to the streetwear midweight cut than to a slim fashion tee or to an oversized skate cut. The two All-Over Print Illadelph tees run slightly relaxed because the dye-sublimation process requires a polyester blend cut in a looser pattern. If you wear a medium in the Signature, the same size in the AOP will feel a touch roomier through the body and sleeves. Sizing up on AOP is rarely necessary.

The Yellow Nebula Shirt is part of Mothership's drop-based apparel program rather than continuous production. It's not a one-time numbered edition, but Mothership does not aggressively restock its tees — when a size sells through, the brand often moves to a different graphic or colorway in the next cycle rather than reordering the same SKU. Effectively this means treating any Mothership tee in stock as a limited window. At $55 the Yellow Nebula sits at the upper end of glass-brand tee pricing, justified by higher-stop screen-print production and the brand's collector cachet.

The Signature is a clean Illadelph wordmark — chest-centered, single-color screen print on a solid base. The Camo Logo takes the same script lockup but lifts it from a military camo background printed across the front of the tee, which gives it a more streetwear-aligned read. The All-Over Print tees (white and black) carry an edge-to-edge sublimated Illadelph graphic that wraps the entire garment including the back, sleeves, and through the seams. Signature is the daily uniform piece; Camo Logo is the streetwear flex; All-Over Print is the statement.

Mixed by design. The Mothership Yellow Nebula and the Illadelph Signature, Camo Logo and Rasta tees are screen-printed on cotton blanks — durable, slightly textured graphics that sit on top of the fabric. The two Illadelph All-Over Print tees (white and black) are dye-sublimated on polyester-blend blanks, with the graphic bonded into the fiber itself. The technical tradeoff: screen-print gives you cotton hand feel with a localized graphic; sublimation gives you a smoother synthetic hand feel with edge-to-edge coverage and a graphic that physically cannot crack or peel.

The Mothership Yellow Nebula is the strongest single-piece gift in this collection if the recipient owns or follows Mothership Glass — the matching tee to a brand whose rigs go for four figures carries real signal. For an Illadelph collector, the Camo Logo is the most universally wearable. If the recipient is a generalist heady-glass enthusiast without a specific brand allegiance, the Black All-Over Print Illadelph reads loudest and works year-round. Pair any tee with a piece from cleaning supplies or dabbing tools for a complete kit-style gift.

Screen-print and sublimation behave differently. Screen-print graphics (Signature, Camo Logo, Rasta, Yellow Nebula) gradually soften and lose a small amount of opacity over hundreds of wash cycles, but the print remains intact if you wash cold and skip the dryer. Heat is the primary fade accelerator — tumble drying a screen-print tee shortens its visual life by years. Dye-sublimation graphics (the two All-Over Print Illadelphs) physically cannot fade in the conventional sense because the dye is bonded into the polyester fiber. They can lose some vibrancy through fabric pilling over time but the graphic itself does not wash out. Cold wash inside-out, hang dry, no bleach for either.

Both brands print in the United States on standard apparel blanks. Illadelph operates apparel printing out of its Philadelphia base; Mothership produces apparel through partners in the Pacific Northwest near its Bellingham glass studio. The blanks themselves are sourced from US apparel manufacturers — typical heavyweight cotton for screen-print tees, polyester-blend for sublimation. Country-of-origin on the blanks may vary by production run, but printing and final finishing happen domestically. This is part of why authorized retail tees cost more than overseas knockoffs of the same graphics.

Cold wash, inside-out, gentle cycle, mild detergent — no bleach and no fabric softener (softener can degrade polyester fibers over time). Hang dry rather than tumble dry. Sublimation graphics will not crack or peel under normal washing, but the polyester blend is more sensitive to high heat than cotton, which can cause subtle warping of the print at temperatures above what a household dryer typically delivers. If you must use a dryer, run it on the lowest or no-heat air-fluff setting. Skip ironing the graphic area entirely.
