JETT - Navy Heavyweight Oversized T-Shirt
FEATURES
A proper heavyweight tee. 240gsm cotton with a boxy, oversized cut that hangs the way an oversized tee should. Structured, not sloppy. The ribbed crew neck holds its shape wash after wash, and the weight gives it that expensive drape thin high-street tees can't fake. Wear it on its own, under an open casual shirt, or over shorts on warmer days.
- Heavyweight 100% cotton, 240gsm
- Boxy, oversized fit — size down for a closer cut
- Ribbed crew neck, taped back neck for shape retention
- Side seams and twin needle stitching for a durable finish
- Easy-care, machine washable
- Designed in London, made in small, considered runs
THE JACK MARTIN PROMISE
Distinctive shirts the high street wouldn't dare make. Designed in-house, sold direct.
- Put this next to tees at twice the price on the high street. The quality holds up, the price doesn't!
- Because we design men's shirts in our London HQ and make in our own atelier in Istanbul, you get genuine designer detail without the middleman markup. Machine precision where it counts, handwork where it shows.
- Whether it's the fabric, the cuff, the collar or the fit, every piece carries a detail we've genuinely obsessed over — the kind most brands wouldn't bother with.
Big on purpose! A relaxed, roomy cut with dropped shoulders and extra length for that easy, street-ready drape. Made to sit loose, not fitted. If you prefer a sharper, closer fit, size down; for the full oversized look, take your usual size.
Please note that the measurements in the size chart are the product's own measurements. Do not take the measurement while the item is on. Lay down your favourite piece, measure it and compare it with our chart.
