The difference between custom gym shirts that sell out in 48 hours and shirts that sit on a shelf for six months comes down to three things: the right blank, the right print method, and the right system for getting them into members' hands.
At Forever Fierce, we've printed custom apparel for over 500 gyms since 2008. We've seen every mistake — and every winning formula. This guide covers everything you need to know about creating custom gym shirts that members fight over, wear everywhere, and keep ordering.
Choosing the Right Blank for Custom Gym Shirts
The "blank" is the base shirt before any printing happens. This single decision affects how your shirts feel, fit, drape, and hold up after dozens of washes. Your blank choice matters more than your design — because nobody wears an uncomfortable shirt twice, no matter how cool the graphic is.
Here's what to consider:
Fabric weight and feel. For gym apparel, you generally want something in the 4.0–5.3 oz range. Lighter weights (4.0–4.5 oz) feel premium and breathable — ideal for workout tees. Mid-weight (4.5–5.3 oz) works better for everyday wear and holds up to more aggressive printing. Anything over 5.5 oz starts feeling heavy and boxy.
Fabric blend. 100% cotton gives you the best print quality and a classic feel. Cotton-poly blends (like 60/40 or tri-blends) are softer, more fitted, and resist shrinking better. Tri-blends (cotton/poly/rayon) have that premium retail feel members love. The tradeoff: blends can be slightly trickier to print on, especially with lighter ink colors.
Fit and cut. The days of one-size-fits-all boxy tees are over. Your members want options — fitted cuts, relaxed fits, cropped styles, tank tops, long sleeves. Offering variety across drops keeps things fresh and gives every member something they'll reach for.
Brand matters. Bella+Canvas, Next Level, and Comfort Colors are the most popular blanks in the gym apparel space right now. Each has a distinct feel. Bella+Canvas 3001 is the industry workhorse for a reason — retail-quality fit at a reasonable price. Comfort Colors brings that garment-dyed, broken-in look. Next Level offers excellent tri-blend options.
Screen Printing vs. DTG vs. DTF: Which Is Best for Gym Shirts?
There are three main print methods for custom gym shirts, and each has its place:
Screen printing is the gold standard for gym apparel. It produces vibrant, durable prints that last hundreds of washes. The ink sits on top of the fabric, giving you bold colors and sharp details. It's most cost-effective at higher quantities (24+ pieces per design). For a deep dive on print methods, check out our screen printing vs. DTG comparison.
DTG (Direct to Garment) prints ink directly into the fabric, similar to an inkjet printer on paper. It's great for photo-realistic designs and small runs (1–23 pieces). The feel is softer since the ink absorbs into the fibers. Downsides: less vibrant on dark shirts, higher per-unit cost at volume, and prints can fade faster than screen printing.
DTF (Direct to Film) is the newest option. A design is printed onto a film, then heat-transferred to the garment. It works on virtually any fabric, produces good detail, and is cost-effective for small runs. Quality has improved dramatically, but screen printing still wins on durability and vibrancy for most gym apparel applications.
The bottom line: If you're running a preorder drop with 50+ shirts across sizes, screen printing gives you the best combination of quality, durability, and cost. For one-off pieces or very small runs, DTG or DTF fills the gap.
How to Design Custom Gym Shirts That Sell
Design is where most gym owners either nail it or miss completely. The shirts that sell out have a few things in common:
They're wearable outside the gym. The best-selling gym shirts look good at the grocery store, at brunch, or picking up kids from school. If your design only works inside the gym, you're limiting your audience and your brand's visibility. Think streetwear, not sportswear.
They use restraint. One strong graphic element, clean typography, and intentional placement. The urge to fill every inch of the shirt with text, logos, and graphics is the number one design mistake we see. White space is your friend.
They tell a story. Whether it's your gym's founding year, a motivational phrase your community actually uses, or a design tied to a specific event — shirts with meaning outsell generic branded tees every time.
They rotate. Running the same design for years kills excitement. The gyms with the best apparel programs plan seasonal collections with fresh designs that give members a reason to buy again. Our full design guide covers the specifics of what works.
The Preorder Model: How Smart Gyms Sell Custom Shirts
The old model of buying 200 shirts upfront and hoping they sell is dead. The gyms crushing their apparel programs in 2026 use a preorder system — and it changes everything.
Here's how it works: You open a branded online store for a set window (typically 7–14 days). Members browse the designs, pick their sizes, and pay upfront. Once the window closes, you place the order for exactly what was sold. No leftover inventory. No guessing on sizes. No upfront investment sitting in boxes.
This is exactly the system Forever Fierce built for gym owners. We handle the webstore setup, design, printing, and fulfillment — the gym owner just promotes the drop to their members.
The results speak for themselves. CrossFit Bemidji runs regular preorder drops and never carries inventory risk. Kingman CrossFit uses the system to build community excitement around every new collection.
Pricing Custom Gym Shirts for Profit
Getting the pricing right is critical. Too high and members won't buy. Too low and you're leaving money on the table — or worse, losing money.
The standard markup for gym apparel is 2x–2.5x your cost. If a printed shirt costs you $12, you'd retail it between $24 and $30. Most gym shirts land in the $25–$35 retail range, which members expect and accept for quality custom apparel.
Your cost per shirt depends on blank choice, print method, number of colors, and order quantity. Screen printing gets cheaper per unit as quantities increase — another reason the preorder model works so well. For a complete breakdown, our pricing guide covers the math in detail.
Don't forget the revenue potential. A gym with 150 members running 4 drops per year, where 40% of members buy an average of 1.5 items at $30 each — that's $27,000 in annual apparel revenue. At a 50% margin, that's $13,500 in profit with zero inventory risk. That's a real revenue stream on top of memberships.
Marketing Your Custom Gym Shirt Drop
You can have the best designs in the world, but if members don't know about the drop, they can't buy. The gyms with the highest sell-through rates follow a simple marketing playbook:
Tease before you launch. Post design previews 3–5 days before the store opens. Show mockups, close-up details, maybe a coach wearing a sample. Build anticipation.
Create urgency. Limited-time windows (7–14 days) and limited editions drive action. "This design will never be reprinted" is a powerful motivator.
Make it easy. One link, one store, sizes clearly listed, simple checkout. Every friction point costs you sales.
Use social proof. When members get their shirts, encourage them to post photos. Repost every single one. Nothing sells the next drop better than seeing real people in the current one.
Incentivize bundles. Offer a small discount for buying 2+ items. It increases average order value and gets more of your brand out into the world. Our incentives guide breaks down what works.

Getting Started With Custom Gym Shirts
If you're ready to launch custom shirts for your gym, here's the fastest path:
Option 1: Full-service partner. Work with a company like Forever Fierce that handles everything — design, printing, webstore, fulfillment. You focus on promoting the drop to your members. This is the lowest-effort, lowest-risk approach and the one most successful gym apparel programs use. See how it works →
Option 2: DIY with a local printer. Find a reputable local screen printer, provide your designs, manage sizing and ordering yourself, and handle distribution. More work, more control, but also more risk if you're guessing on quantities.
Option 3: Print-on-demand. Services like Printful or Printify print and ship individual orders as they come in. Zero risk, but higher per-unit costs, limited print quality, and no community-building around drops.
For most gym owners, the full-service model hits the sweet spot — professional quality, zero inventory risk, and a system designed specifically for the gym space. Check out our portfolio to see what's possible.
Frequently Asked Questions
How much do custom gym shirts cost to make?
Cost depends on blank quality, print method, and order size. Screen-printed shirts on quality blanks typically run $8–$15 per unit at gym-sized quantities (50–200 pieces). DTG and DTF prints cost $12–$20+ per unit for smaller runs. With a preorder system, you're only producing what's already sold, so your cost per unit stays predictable.
What's the minimum order for custom gym shirts?
It depends on the print method. Screen printing typically requires 24+ pieces per design to be cost-effective. DTG and DTF can handle single pieces. With Forever Fierce's preorder system, there's no minimum — we print exactly what your members order.
How long does it take to get custom gym shirts made?
Standard turnaround for screen-printed gym apparel is 2–3 weeks from order placement to delivery. Rush orders can sometimes be completed in 7–10 days. Forever Fierce's standard turnaround is 2 weeks from webstore close, and we offer expedited options for events and competitions.
Should I keep gym shirt inventory or use preorders?
Preorders are better for almost every gym. You eliminate inventory risk, get exact sizing data, and create urgency with limited ordering windows. The only case for keeping inventory is if you want shirts available for walk-in purchases at your front desk — and even then, a small restock of bestsellers is smarter than a big upfront buy.
What designs sell best for gym shirts?
Clean, wearable designs consistently outsell busy, logo-heavy ones. The top sellers across our 500+ gym clients tend to be minimalist logos on the front with a larger back graphic, event-specific commemorative designs, and seasonal collections that feel fresh and current.
