Lake Ontario Mammoth Heavyweight T-Shirt | Navy

82,15 kr. DKK

A clean, understated take on the Mammoth Collection.

The Lake Ontario Mammoth Heavyweight T-Shirt features the Lake Ontario mammoth design with “EST. 9000 BCE” printed over the left-chest area for a subtle, heritage-inspired look. The shirt uses a heavier 5 oz fabric with a regular, slightly relaxed fit that works well for everyday wear and casual streetwear.

Details:
• Lake Ontario Mammoth graphic printed at the left chest
• Gildan 5000 Heavyweight T-Shirt
• 100% cotton on standard solid colours
• Heavyweight 5 oz fabric
• Pre-shrunk jersey knit
• Regular fit
• Available in sizes S–5XL
• Printed on demand
• Made to order

Part of the Soundmark Vibe Mammoth Collection, the smaller chest placement lets the prehistoric Lake Ontario design function more like a brand emblem than a large souvenir graphic.

Inspired by Lake Ontario’s glacial origins and created amid the 2026 “Lake America” naming controversy, the Mammoth Collection gives Great Lakes identity a prehistoric twist.

Whatever the map says, the vibe is Lake Ontario.

Soundmark Vibe — Great Lakes energy, prehistoric roots.

Our suppliers provide the measurements. There may be a deviation of up to 2 inches (5 cm) in the product dimensions.

A useful tip! Compare measurements with a product you already own at home by measuring it and matching it to the sizes in this guide.

A Length

Start the tape at the collar's top next to the shirt's highest point on the shoulder. Extend the tape to the shirt's bottom.

B Width

Begin at the seam just under one sleeve and extend the tape across to the seam under the other sleeve.

C Sleeve length

Start measuring from the back center of the collar, follow the top seam of the sleeve to the shoulder, secure the tape at the shoulder, and continue down to the end of the sleeve.
