Highly Recommend! This was our first time ordering shirts and Jason walked me through the whole process and was patient enough to provide me with shirt options and his honest opinions of which would suit my needs better. Communication was quick, prices were great, and quality is amazing.
Excellent service and great quality!! Also fast service !
I ordered two shirts, white printing on black for the first and black printing on white for the other. The shirts look very good. Sharp and clean. The shirts themselves seem of decent quality.
Many thanks to T shirt elephant. They rushed my order and offered delivery so I could get my summer camp t shirts on time! The t shirts themselves were fun to design and looked great, but the customer service saved the day!
Our experience with T-Shirt Elephant was excellent. The product came just as we were expecting and arrived quicker than we thought it would.

Fabric & Construction
- 100% polyester interlock — lightweight, breathable performance fabric
- 3.8 oz / 130 GSM — ultra-lightweight for maximum breathability and comfort
- Moisture-wicking technology — draws sweat away from the body to the surface for rapid evaporation

- UV protection — polyester provides inherent sun protection for outdoor activities
- Self-fabric collar — clean, modern neckline
- Heat-seal label — tagless comfort

Why Choose Performance Over Cotton for Long Sleeves?
- Moisture management — cotton absorbs sweat and stays wet; polyester wicks it away and dries in minutes
- Wrinkle-free — looks crisp straight out of the bag, no ironing needed
- Odour resistance — doesn't hold odour like cotton after a long day
- Sun protection — full arm coverage plus UV-blocking polyester for outdoor crews
- Lighter weight — at 3.8 oz, it breathes better than a cotton long sleeve for active work
- Colour retention — polyester resists fading from washing and sun exposure
Best Print Methods for the S350LS
- Screen Printing — excellent results with athletic-grade polyester inks. Bold, durable prints for team logos and event graphics.
- DTF (Direct-to-Film) — outstanding on polyester. Vibrant full-colour transfers with excellent adhesion and durability.
- Heat Transfer / Vinyl — the smooth polyester surface provides superior adhesion. Ideal for names, numbers, and team customization.
- Embroidery — works well for small left-chest logos. Use lightweight backing for best results on this light fabric.
- Sublimation — 100% polyester means sublimation is an option for all-over prints on white/light colours.
