It’s like you gave my shirt superpowers

In one day, the green Neat shirt stopped the rain when I was outside and then had me looking 100% dry after 6 hours at an all day festival in 90 degree heat.

    It is not sweatproof

    Thank you for sharing your feedback. I’m really sorry to hear that the Sweat Defender Crew didn’t meet your expectations. That’s frustrating, and it’s not the experience we want anyone to have.

    Sweat performance can vary depending on factors like activity level, climate, and individual perspiration, but we absolutely want to understand what happened in your case and make this right if we can. Please reach out to our support team with a bit more detail about how and when you noticed the issue, and we’ll be happy to review options to help resolve this for you.

    We appreciate you taking the time to leave an honest review.

    Fantastic

    The best polos and sweaters I ve purchased.

    The marvel of not having to worry about sweat stains (chest and back) is priceless.

    Now, please, make the world a brtter place and make white polos and sweaters (not undershirts).

    Thank you so much for the kind words,we’re thrilled to hear how much you’re enjoying the polos and sweaters, and that the sweat-proof performance is making a real difference for you. That’s exactly what we aim for.

    We also love your suggestion about white polos and sweaters (not undershirts). You’re not alone in asking for this, and feedback like yours is incredibly helpful as we plan future releases. We’ve shared this with our product team, and it’s definitely on our radar.

    Sweat Defender V-Neck Undershirt

    Literally the best t-shirt of all time

    Whether or not you need/like the sweat-hiding feature, this is the perfect t-shirt in every single way. I've worn a black v-neck t-shirt every day for over ten years and have been on a LONG journey to find the perfect shirt. This shirt is that perfect shirt. I now own 8 of them (and hope to order more but the Large, black v-neck has been out of stock for months). The texture is extremely soft while also being just the right weight. The black stays a deep black even after numerous washes. The sleeves are just the right length and circumference. The length of the shirt is perfect. I'm 6'5" so I worried it would be too short but the Large is perfect. Not too short for me, and not too long for my 6'1" son who I've also gotten these shirts for. The v of the v-neck is subtle - just enough to ease the neck but not super-deep or anything weird. I literally do not have a single complaint about this shirt except for my inability to order more since it has been out of stock for many months. PLEASE restock the Black Sweat Defender V-Neck Undershirt in Large! PLEASE! I promise I'll buy at least 5 more for me, and likely many more for friends and family!

    Wow! Thank you for such an incredible review. Reading this honestly made our day.

    Hearing that this has become the perfect black v-neck after a ten-year search is exactly why we do what we do. The fact that you’ve dialed in every detail — fabric feel, weight, color retention, sleeve fit, length (especially at 6'5"), and even the depth of the v-neck, tells us we got this one right, and we’re genuinely grateful you took the time to share it.

    We also completely hear you on the frustration around the Black Sweat Defender V-Neck in Large being out of stock. You’re definitely not alone there. Feedback like this is being passed directly to our product and inventory team, and restocking this exact style and size is a priority because of customers like you.

    Thank you again for the trust, the enthusiasm, and for spreading the word to your son, friends, and family. We can’t wait to get more back in stock so you can add those next five (and more) to your lineup.

    The feel of the shirt is great. Unfortunately, my underarms was still able to sweat through the shirt.

    Thank you for taking the time to share your experience. We’re glad to hear you liked the feel of the shirt, but we’re genuinely sorry to hear that the underarm sweat protection didn’t perform as you expected.

    While the built-in sweat guards are designed to significantly reduce visible sweat, results can vary based on factors like body chemistry, activity level, and environment. That said, we never want you to feel disappointed with your purchase. Our support team would be happy to learn more about how you were using the shirt and see what options we can offer to help improve your experience.

    We really appreciate your honest feedback, it helps us continue improving our products.
