I've never tried Techwear shirts and I'm sure they are of great quality.
But I've ordered my shooting jersey from G2Gemini and don't regret it.
The jersey is of excellent quality, design and performance, very light, breathable and moisture vicking.
It really keeps you cool in hot days.
I've ordered ready made design for STI with additional logos. Also, good thing about G2Gemini is that they don't need written proof from each of your sponsors with permission to wear they logos, just tick the box in order form.
Design approval took only a week and in three weeks the jersey was shipped.
And good addition is matching hoodye
