The Go Programming Language T-shirt - Mashup edition

The Go Programming Language T-shirt - Mashup edition

The best model you can find, top printing quality and a paired sticker for free

Continuing on our efforts to make you a happier unix lover, we're proud to announce this awesome t-shirt for every Go developer or not! The number of t-shirt models and print variants that we tried is countless, but we're now happy and relieved to be introducing the top-notch result.

The Go Mashup T-Shirt

The t-shirt model

We literally tried tens of different models before settling on this one. We like thin necks, great texture and precise sewing. Colors must be bright without looking fake, the texture must be soft but not too heavy. Finally, style can't be that of the '60s, we care about body and sleeves of the right length, fit that's not too large nor too thin, neck of the right thickness.

M 50cm / 19.69" 70cm / 27.56"
L 52cm / 20.47" 71cm / 27.95"
XL 54cm / 21.26" 73cm / 28.74"
XXL 60cm / 23.62" 74cm / 29.13"


The t-shirt print

There are many ways for transferring a design onto a t-shirt, but when you want quality and durability serigraphy is the choice. This technique uses a frame with actual liquid paint being poured on it. The result looks and feels great and lasts forever.


The texture, Black melange (100% cotton)

The t-shirts are made from extra-soft peached-cotton at 140g/m2 (not too heavy, not too light), nothing in common with many plastic-bag t-shirts you can find on the market.

A free sticker with every t-shirt

Every t-shirt comes with a free sticker with the same design and color as the T-shirt. We couldn't resist: wearing the Go Mashup t-shirt is already nice, but wearing it with a paired sticker on the laptop feels really like another level :P
