Worked great for summer

So I got one of those Men's Sweat Proof Undershirts, the Original Fit Crewneck. It was getting hot out and I sweat a lot, especially at work. This thing actually worked! No wet spots under my arms, which was a huge relief. I just threw it in the wash with my other clothes. Super easy, no fuss. Glad I tried it.

Good value with the bundle

I was looking for some sweat-proof undershirts and Thompson Tee popped up. I grabbed a V-neck 4-Pack and saved a good chunk compared to buying them individually. The free shipping over $50 was a nice bonus too. Felt like I got a solid deal for the quality. Definitely worth it for the price I paid.

These undershirts are amazing!

I finally got a couple of the Bamboo Viscose Undershirts and they are incredible! I've tried other brands before but these Hydro-Shield ones are just on another level. My shirts stay completely dry all day, even when I'm running around. The bamboo fabric is so soft and comfortable too. I'm definitely going to buy more of these, maybe a multi-pack next time! My old undershirts are going in the donation bin.

Ordering, shipping, and shirt quality

I ordered two Slim Fit Crewneck undershirts on a Monday evening. The website was easy to navigate and the checkout process was smooth. I received a confirmation email almost instantly. The package arrived on Friday morning, which was pretty quick for standard shipping to my area (rural Montana). The shirts themselves are well-made. The fabric feels soft, and the sweat-proof barrier under the arms seems effective. I wore one all day yesterday in warmer weather and had no visible sweat marks. Washing instructions were clear, and the shirts held their shape after the first wash. I haven't needed customer support, so I can't speak to that, but the overall experience was positive.

How long does shipping usually take to like, California? Need some for a trip coming up.

R Rosa Carter 1 month ago

For me, to SoCal, it's usually like 3-5 business days. Depends on if you pick standard shipping.

K Kate L. 1 month ago

I'm in NorCal and it was pretty quick last time, maybe 4 days. If you're in a rush, they might have expedited options.

What's the deal with sizing? Should I go true to size or size up/down? Don't want it too tight under my regular shirts.

L Laura 4 weeks ago

I'd say stick with your normal t-shirt size. They're meant to be a base layer so they're not super baggy.

J James Silva 4 weeks ago

I went with my usual and it was fine. They have a size chart too, you can double check against that.

Is there a first-time buyer discount? Saw something about 15% off somewhere but can't find a code.

K Kevin N. 1 month ago

Usually, it pops up when you first visit the site or if you sign up for their emails. Check your spam folder if you signed up.

P Phil 1 month ago

I got mine by signing up for their newsletter. It's a single-use code though, so use it wisely!

Are these really better than Ejis? I've tried Ejis and they were okay but not perfect.

T Todd Bennett 3 weeks ago

I've only used Thompson Tee, but my buddy who tried both says these are way better for heavy sweating. The pad area is more effective for him.

P Phil 3 weeks ago

I switched from Ejis to Thompson Tee and definitely prefer these. The sweat barrier feels more robust and less noticeable.

Thinking of trying these out, but like, do they actually work for heavy sweating? I've tried other stuff and it's always a bust.

S Shane 1 month ago

Yeah, they totally do. I have hyperhidrosis and these are the only things that keep me from soaking through my shirts. It's a game changer.

S Steve 4 weeks ago

Honestly, I was skeptical too, but they're legit. I wear them under dress shirts for work and no more pit stains. Even in summer.

Hey, thinking of ordering a 4-pack. Do those multi-packs count for free shipping? Or is it only over a certain dollar amount after discounts?

R Rachel N. 1 month ago

I think it's any order over $50, so a 4-pack would probably hit that. I got free shipping on my last multi-pack order.

D David 1 month ago

Yeah, it's usually based on the total before shipping is calculated, but after any discounts. Most likely yes.
