The short version
If you don't want to read three minutes about hat fabric and color, here's the take. Dark caps show sweat. Light caps don't. Mesh-back trucker hats breathe better than baseball caps when it's actually hot out. The embroidered patch on a Places Moments cap doesn't care either way, it holds up clean.
That covers most of what customers ask me before they pick a cap for summer. The rest of this is the operator's version of why.
Which Places Moments hats show sweat the most
The dark ones, honestly. The black Dirty Martini, the blue Côte, the Nixon cap. Those are the colorways where a band of sweat across the front panel is going to read on the fabric. That isn't a Places Moments thing, it's a dark-fabric thing, the same way a black T-shirt tells on you in July.
If you wear a darker cap on a 90-degree day, you'll see it. The patch itself stays sharp, the stitching doesn't move, but the crown fabric around it will say something.
Which ones hide it (and the one I'd grab first for summer)
The cream Côte cap. That one is a great summer hat. It hides sweat the way a lighter shirt does, which is to say almost completely, and it's actually one of our most popular drops. Nobody buying the lighter caps has come back with a sweat complaint, and that isn't survivor bias, it's just lighter fabric doing its job.
If you're picking a cap for July or August and you don't want to think about it, go light. Cream, off-white, anything pale on the crown is going to outperform a black one in heat.
Mesh-back trucker or baseball cap when it's actually hot
Mesh-back trucker, every time. The side and back panels are mesh, air moves through them, and the foam front panel sits a little forward of your forehead instead of pressing against it. It breathes better in a way you can actually feel.
A baseball cap is still a good summer cap if you prefer the silhouette or you want something dressier. But if the question is purely "which one stays cooler when it's hot," the trucker wins. If you haven't seen them, here's the mesh-back trucker collection.
What about the embroidered patch?
The patch is fine. It's high quality, it's stitched in tight, and a sweaty crown doesn't change its behavior at all. You won't see wicking, you won't see color transfer onto your forehead, you won't see the thread loosen. The cap can be washed and cleaned. The embroidery isn't the part of the hat you need to think about in summer, it's the fabric around it.
One thing to know before you wear a new cap in 90-degree heat
Just know it's going to get dirty. Same as a shirt. If you want to keep one pristine, don't take it out in real heat.
What I wouldn't do: play golf in a baseball cap (a trucker, maybe), or jump in the ocean with one. Normal stuff, not complicated. If you'd hesitate to do it in a shirt, hesitate to do it in a hat. If you jump in the water with a shirt, it's going to get wet, and a hat behaves the same way.
If you're picking one cap for summer
Two simple calls. Go lighter on color, or go with a mesh-back trucker. Do both and you've solved the problem before you wear it. The cream Côte is the one I'd reach for on a hot day if you want something low-maintenance, and if you want airflow on top of that, look at the baseball cap collection for lighter colorways or grab a mesh-back. Drops sell out, so if there's a specific colorway you've been watching, don't sleep on it.
