Trasnsition bag to the gym .... overkill?

So I got a new tri bag and was curious to see what peoples thoughts were on taking my old TYR tri bag to the gym, is it overkill? I take 2 bags with my in the first place, one for my swim stuff and one for my clothes to change in. I was thinking about using the TYR bag but the thing is huge!

I think it depends on whether you can get past the “poser” factor.

I take two bags as well. A netted bag for the swim stuff and a soccer duffel bag for the other stuff.
