Custom Performance Shirts UK – Fully Sublimated & Manufactured In-House
When training intensity increases, your kit needs to stay lightweight, breathable and durable. Our Custom Performance T-Shirts UK are fully sublimated and manufactured in-house at Brick & Grit, with each garment produced from raw polyester fabric inside our Aylesbury workshop. Every stage — from print setup to cutting and final stitch — is handled under one roof, allowing us to maintain full control over fit, panel alignment and overall construction quality.
Rather than printing onto pre-made stock T-shirts, we sublimate your design directly into the fibres before assembly. This ensures long-lasting colour without cracking, peeling or fading over time. Our custom performance T-shirts UK service operates on a standard production time of 3–5 working days from artwork approval and payment confirmation, with express options available if you need a faster turnaround.
Engineered for Performance Use
These fully sublimated performance shirts are designed for combat sports environments. They are lightweight, moisture-wicking, and built for unrestricted movement.
Suitable for:
- Training sessions
- Fight walkouts and event builds
- Gym uniforms and team kits
- Boxing, Muay Thai, MMA and BJJ clubs
- Independent fightwear brands
Because we control the full manufacturing process internally, sizing and construction remain consistent across every order and repeat run. Many fighters also pair these shirts with custom fight shorts when training for grappling, MMA or conditioning sessions. For striking camps and pad work, athletes often combine them with custom Muay Thai shorts for a full training kit.
Fully Sublimated Construction
Each garment begins as performance fabric on the roll. Your artwork is sublimated across the material before cutting and sewing, allowing complete design freedom across the entire shirt.
Our build process includes:
- Lightweight breathable polyester performance fabric
- True all-over sublimation coverage
- Athletic cut for unrestricted movement
- Moisture-wicking properties
- Reinforced collar and seam construction
- Men’s, women’s, and youth sizing available
Because the ink becomes part of the fabric itself, colours remain sharp even after repeated washing and hard training cycles. We also retain artwork and production specifications for accurate future restocks.

Designed for Team Identity
Performance shirts represent your gym daily in training and under lights on fight night, often worn alongside custom boxing shorts during camps and walkouts. We manufacture with this in mind, ensuring clean finishes, accurate branding placement, and professional presentation.
Since production remains fully in-house, we maintain strict quality oversight before dispatch.

- No minimum order for single custom shirts
- Bulk runs for gym uniforms and fight teams
- Fast UK restocks without overseas delays

What fabric do you use? We use lightweight, breathable polyester performance fabric designed for training environments. The material is moisture-wicking and built for unrestricted movement.
Will the design crack or fade? No. Because the artwork is sublimated into the fibres, colours will not crack, peel or wash away like surface prints.

Starting Guide
Single-piece custom performance shirts start from £45. Final pricing depends on sizing and design complexity. We confirm timelines before production begins — and we deliver as agreed.
