GSM: what fabric weight actually tells you
GSM (grams per square meter) is the most useful single number on a blank spec sheet. It tells you how dense the fabric is, which translates directly to how the garment feels, drapes, and holds a print.
- 140-180 GSM tees: light, breathable, drapey. Good for giveaways, athletic wear, and hot climates. Can feel thin if you want weight.
- 180-210 GSM tees: the midweight standard. Balanced feel, prints well, the default for most merch.
- 230-255 GSM tees: heavyweight. Structured, substantial, holds its shape, the weight class behind most streetwear tees.
- Fleece weights: hoodies, crewnecks, and sweatpants. Around 215 to 290 GSM is often lighter fleece, 320 to 380 GSM is often midweight, and higher weights usually feel denser. Construction, fiber content, and brushing can change how two garments at the same GSM feel.
- Very heavy fleece: availability and cost vary substantially by supplier and color. If a particular weight matters, include it in your quote.

Fits: classic, relaxed, and cropped
Weight and fit together define how a blank reads. A classic fit is the straight, familiar cut that works for the widest range of bodies, the safe call for clubs, teams, and company merch. A relaxed or boxy fit is wider in the body with a dropped shoulder; paired with heavyweight fabric, it's the contemporary streetwear silhouette. A cropped fit shortens the body and is a deliberate fashion choice rather than a crowd-pleaser. If your audience is broad, lead with classic; if you're building a brand look, relaxed heavyweight is usually where to start. Compare cuts side by side in our styles catalog and check measurements against the size guide.
Fabric content: cotton, blends, and what "ringspun" means
100% cotton is the workhorse: it prints well with every method we offer and ages nicely. Within cotton, the spinning process matters, ringspun cotton is spun into a finer, smoother yarn than basic open-end cotton, and combed ringspun goes a step further by removing short fibers before spinning. The result is a noticeably softer surface that takes fine print detail better.
Cotton/poly blends add softness, drape, and wrinkle resistance, and they're common in fleece. The trade-off: high polyester content can cause dye migration under screen printing on dark garments, and DTG strongly prefers cotton. If your decoration plan is set, choose the fabric with it in mind.
Construction details worth checking
Two spec-sheet details separate budget blanks from premium ones. Side-seamed garments are cut from flat panels and sewn, producing a consistent, tailored shape; tubular garments are knit as a tube, which is cheaper but fits less precisely and can twist after washing. Shoulder-to-shoulder taping, a fabric strip reinforcing the neck and shoulder seams, keeps the collar from stretching out and is standard on better blanks. Neither detail shows up in a product photo, but both show up after ten washes.
Matching blank tier to the job
There's no universally "best" blank, there's the right tier for what the garment has to do. For a giveaway or event tee, a light-to-midweight basic is the rational choice: people are getting it free, and budget goes further on quantity. For club and team merch, a solid midweight with side seams hits the durability-to-cost sweet spot. For a retail-quality brand drop, anything people pay for, heavyweight, combed ringspun, side-seamed blanks are worth it, because customers judge the garment before they judge the print.
One order can mix tiers. Manicule's conference run paired relaxed tees and long sleeves with four 500 GSM premium hoodies, spending the heavier blank only where it counted. Pairio went the other way and ordered a single tier, three heavyweight fleece quarter-zips for the founding team.
