Somebody is just showing off.

I’ve actually been wanting something like this!  We have our first heat warnings here in central IL and it is mainly the sun beating down.  I learned in my time in MS that keeping the sun off you with the right fabric is more than worth the trade off of wearing long sleeves.

I have a pair of skin tone compression sleeves I would wear.  I did not grab them before I left town this week, so I am going to try to wear some of my sun shirts this afternoon.  (My normal summer wear around the house is shirts and a log sleeved sun shirt.)

Any consideration of a long sleeved version, @concertman1971?  It may be too niche, but who knows.

I know long sleeve versions of these would be helpful out in the desert. Some of us old guys have some pretty sun damaged arms. And ears.

I'm in Salem, Mo. watching the Cardinals game and that looks miserable. Feel bad for C.B. today. He's hanging in there.

@umpstu and @The Man in Blue

I do have some "average white dude skin tone" arm sleeves that are SPF 50. 3/4 sleeve from the bicep to the wrist. If interested,  let me know and I can see if I have your size.

Is there a no logo version? I’m interested but wonder if it would feel like a bad neck tattoo

I think it was very tastefully done with the contrast.

It's not a Nike white on black and goes with some of the more tasteful touches an older New Balance line that was a slight contrast and damn near tone-on-tone.

I can appreciate that and not trying to hate. For me, in those pictures, it jumped out. I'm one of those that doesn't want brand logos on anything and takes the badges off their cars.

[MadMax]

I commend and appreciate ya @concertman1971 (Tim!) for bringing these to market. You’re doing something that New Balance was too 🐓 💩 to continue (ended it as soon as they were out as MLBU suppliers), and Nike is too chicken 🐓 💩 to try. 

Yes, indeed, I want someone to ask, “Hey, where’d you get that?”

But..will it come in Red for those cursed to wear Navy in the playoffs? (Cough cough Illinois, specifically, and others)

So, if navy, then why this obsession with red (for undershirt)??! Is it that stooooopid adage that undershirt should match last trim stripe?? 🤨 Ridiculous. By that same logic, then black shirts from that “traditional” period should have been white! And, if we carry this into the panel-style shirts on the umpire scene from 2016 thru 2019/20, then the undershirt for black should be grey. Then, if we carry this into the 20/21 placard-style shirts now wore by MLBU, then the undershirt color should be … sky blue! 😱

Maddening, huh? Kinda silly, kinda petty, kinda pointless, right? 

Well so are those edicts and “rules” that stipulate what we must wear! (Notably and especially when those self-deigned rulemakers didn’t buy or provide them for you!) 

Really… why can’t that mock-t undershirt be navy? Heck, it could (then) be used by softball, too!

Call me crazy but I think I’ve seen some mlb guys wear a sky blue undershirt this year… maybe I’m imagining it though

@Velho If you can see the logo on these, you must shoot 122.7 on Trackman!! LOL Enduro from @DerekGDS looking SHARP over the Locked In Mock

 

Get that Malachi Moore "look"  (not endorsed by him, he just looks sharp in a mock)

I saw the pictures before I read the comment and was thinking how much I had to hunt for the logo.

These views sold me because I do like the product concept (and not just because you mentioned Malachi (whom I've met a few times). Guess I'm just not creative enough to realize that from the bare pictures.

I'll put it on the shopping list - along with new pants after I get back on track with losing some more weight.

Umm.  I wear a coordinated grey under my black panel . . . and I have a coordinated blue for my MLB (which nobody else has, so I never get to wear it).  I really like wearing either of them under my new Davis BFX convertible pullover, depending on what my partner is wearing on the plate.

When I started, I didn't really dig the red undershirt with the navy shirt . . . now I just do it for the disdain when I have an "I only have navy and powder" partner.

The t-shirt doesn't really bother me too much . . . it is guys who can't get the hat and ballbags to match the shirt who bother me.  If you only have navy and (softball) powder, then why the hell do you even own a black hat and/or black ball bags?

Malachi may look quite dapper with it, but I’m after the Super-Smartie, I-Dare-You-to-Debate-Me Dan Iassogna -look.

@concertman1971, how do you recommend sizing this? I wear an XL shirt on bases, plate, and when wearing street clothes. XL? L?

I am 6'4 208 and wear a L. has a very "compression" fit. If you like it a bit looser, go with the XL.
