They did recommend 16oz however which was way off the mark.
These particular Everlast models had good padding for the mentally disturbed power punchers. You couldn't hear a thing in the boxing gym when I did some quick bag work, and my hands were good!! Fine brand.
At the end you still ask the coach, the peeps here recommend, but you have to use your own judgement, and its not hard, all you have to do is ask.
Spacetime day 1:
ST: hey I'm looking to do a trial/join
coach: sure blah blah blah
ST: so how does this work?
coach: here are gloves, you can buy it here or whatever, gym culture blah blah blah
ST: what weight for the gear?
coach: blah blah 16oz, 12oz, whatever
---boom---
first gym I was with it was 12oz, despite research of many peeps saying use 16 in spars and 12 in practice. Doesn't matter, the coach said 12 is fine all around, so I used 12.
New gym I'm at, he laid down the groundwork and said 16oz in sparring, 12oz for other. So that's what I'm doing.
