Hawaiian vs. Button Down
Both styles come in the same print and fabric. They differ in the collar and the placket, the strip that holds the buttons.
Hawaiian Shirt: A camp collar, also called a Cuban collar, lies flat with an open notch neckline. The placket has extra fabric that folds under. The Hawaiian Shirt is preferred for relaxed days.
Button Down Shirt: A traditional collar that stands upright, with a top button, for a dressier look.
Pocket or no pocket: Either style has the option of coming with or without a pocket, and the print continues across it uninterrupted.

60-Day Print, Quality, and Delivery Guarantee
We offer a 60-Day 100% money back guarantee for damaged, misprinted, or faulty products or even packages lost in the mail.
The 60-Day window starts on the date the order has been delivered. In only very rare circumstances will we ask for the inconvenience of returning defective products, and defective products may be kept or given away after confirming with our team.
Our delivery guarantee covers lost packages once confirmed lost from an investigation from the carrier and a claim has been approved, typically confirming that the last package scan was at the wrong location. We will remake the products or refund orders that meet this condition. Geek Tropical is not responsible for any stolen or delayed packages or lost packages that were the result of an incorrect address on the order.
Button replacement: In case products' buttons were damaged during shipment or during the first wash, we would be happy to mail replacement buttons on request.
Returns & Exchanges
|
Ready-to-Ship / Retail (For products prefixed with "Ready-to-Ship") With exception to products marked as clearance, you may return unused, undamaged, and unwashed merchandise back to our address in the USA within 30 days of purchase to qualify for a product exchange or refund. The hang tag must still be attached to the item. Shipping costs for returns and exchanges are the responsibility of the customer. If the item is in a condition such as being previously worn, washed, or damaged, preventing us from reselling it, we cannot issue an exchange or refund. Should the customer wish to receive the item(s) back, they are responsible for covering postage costs. Ready-to-ship items are clearly marked as such in the product title or on the product page. Ready-to-ship items labeled as clearance or final sale are not eligible for return, exchange, or refund. |
Made-to-Order Although the typical made-to-order policy is no returns and exchanges, we are pleased to offer a 30-day return and exchange policy for our handcrafted-to-order fashion. This window is extended for purchases made between November 1st and December 31st where purchases are eligible for a size exchange until January 31st the following year. The 30-day return and exchange window starts from the date the order was delivered. Postage for the return back to our U.S. address is the customer responsibility, unless the item(s) arrived defective. A 15% stocking fee applies for items made-to-order when returning for a refund. We expect you to understand the material used for sublimated products, shipment timelines, and the sizing charts to make sure your order will be as expected. Because each item is handcrafted exclusively for you, returns and exchanges—while available—generate unnecessary waste and environmental impact. The postage for the return and exchange to return to us is paid by the buyer. Any size exchanges are then shipped out to you free of charge. Please ensure that the item is in a new, unworn, and unwashed condition with the hang tags still attached. We reserve the right to refuse any exchange for these reasons. Before inquiring on a sizing issue or size exchange, we encourage you to double check the sizing on the products received and check them against our size chart. If the product falls outside of the stated tolerances, please reach out to us with images clearly showing the inaccurate sizes with a ruler. This is covered by our guarantee and may be replaced or refunded per customer preference. |

Disclaimer: Due to the handmade and hand-measured nature of our products, measurements may vary by 1–3 cm.
Tip Compare these to a shirt you own. If you’re between sizes, choose based on your preferred fit (roomy vs. tailored). Please see instructions below.
Fit & Tips
- Runs slightly big: The chest and length has extra room for flexibility and comfort. In most cases, order your normal unisex size.
- Fabric note: Our material is a four-way stretch, but we don't recommend you to take that into account. Additionally, the material does not shrink after washing and drying.
- For simplicity, our button ups and Hawaiian shirts have the same sizing, but please note that curvy shirts are completely different.
How to Measure Yourself
- Chest: Wrap measuring tape under your arms at fullest part. Divide the chest measurement by two to get the side-to-side width.
- Shoulder: Measure the width of your shoulders from one shoulder blade to the tip of the other while keeping the tape taut.
- Length: Starting from the base of the back of your neck, measure down your back to the point where you want the shirt to end.
- Sleeve: Starting from the tip of your shoulder, measure straight down your arm.
How to Measure a Flat Shirt
- Chest (Width): Lay the shirt flat and smooth out wrinkles. Measure straight across from one armpit seam to the other. (This number is already the half-chest width; double it if you want the full chest circumference.)
- Shoulder: With the shirt flat, measure from the tip of one shoulder seam straight across to the tip of the other shoulder seam.
- Length: Place the measuring tape at the highest point on the shoulder (where the shoulder seam meets the collar) and measure straight down to the bottom hem of the shirt.
- Sleeve: Start at the top of the shoulder seam (where it meets the sleeve) and measure along the outside edge to the end of the cuff.

Customer Reviews
Overall rating: 4.8 / 5 from 65 reviews.
I really like this shirt. I have a hard time finding shirts that fit me right, since I am short and round. To those who are coming from other brands, this shirt feels like the same fabric as RSVLTS Kunaflex, and the 3X fit me great in the chest and shoulders, just like the other shirt I just mentioned. The sizing chart was perfect, except the length, it was longer than i expected, but not awkwardly long. I am definitely going to order more.
Soft, fits as expected, and the colors pop. Very, very happy with this.
Super cool shirt. The green is a bit dark for me, but, it’s still a big hit. I’ve gotten so many compliments! Again, I will reemphasize, these shirts run large compared to US men’s sizing
Fits great. Maybe my favorite shirt. 6’, 250 lbs. size 2x
Hello! My name is David Mills, and I am the 4X fit model for Old Navy and Ariat. I love that your fun, eye-catching shirts are light and wrinkle-resistant. Your 5X shirts fit well, with a little room to spare! The pocket is well placed with a match to the shirt pattern. This attention to detail deserves praise! I did have a couple of notes - more buttons appear to be needed. When sitting in certain positions, the space between the buttons open up exposing the skin beneath the shirt, as well as perhaps a little too much chest being exposed at the top. Also, with the lapel open, the white backside of the fabric is exposed - and I'm not sure an extra button on top will fix that. Perhaps a small patch of pattern fabric could fill in the void. I love the two shirts I purchased, and I hope to buy another one very soon. Thank you for this opportunity to provide feedback to you. Sincerely, David Mills.
intended as a Christmas gift for my brother who is states away and planning to ship to him. color on the physical shirt is quite bolder than i had anticipated from the image on my monitor
Christmas gift to the man, who is in love with it. said it is the best shirt he has ever been given. Thanks
It's not for me but l know he's going to love it. Can't wait to see him in it. Love the feel of the fabric!
Bought it for my father for Father's Day, and he absolutely loved it. & it fits perfectly.
I have received many many compliments about this design and my VP even loved it
My husband loves Geek Tropical ahirts and this pattern looks so great on him. 10/10. Super comfy, durable, easy to clean, will contonue to get his shirts here for sure.
My husband got lots of compliments on his shirt.
Great shirt! I loved it!
As I grow in sizing, I keep wearing this shirt. It's super cool, the green is the perfect color
Looks great in person! Bought it as a gift and he's gonna love it!
Such a classic shirt, and one of the few circuit board shirts with high quality!
Seems pretty good quality and the pattern is as pictured. He hasn't worn it yet so I'm not sure about durability but it fit well when he tried it on.
Got it for my husband and he loves it! Great fit and design!
I love wearing this shirt. People think it is from Tron. LOL
These shirts are so comfortable. I am wearing it over a teeshirt because my classroom is so cold, but I know I will be able to wear them comfortably without that. My students think they are cool, and I get to be a bit nerdy. The computer circuit pattern is what I wear to our ESPort matches.
Fits like a 3x not a 4x

Store owner replied: Thank you for taking the time to leave a review, Douglas. We're sorry to hear the sizing wasn't what you expected. This is the first we've heard about our updated sizing being too small for the 3XL-5XL range. Could you please measure the width of the shirt and ensure it falls within our sizing tolerances? As our products are handcrafted and measured, discrepancies are very rare but can occur. If the shirt measurements do fall outside our stated tolerances, we'll certainly replace the item or offer a refund, without requiring a return. Your satisfaction is important to us, and we want to ensure you have the fit you expected.
Bought this for my husband who works in IT. He loves it! Very soft and breathable
I love the design on this shirt.
Live the circuit board
The label said 4XL but it’s more like 2XL for a little person. I wouldn’t recommend this item. Save your money and go somewhere else.
Green Computer Circuits Button Up Shirt
Store owner replied: Thank you for sharing your feedback with us. We're genuinely sorry to hear about your sizing concerns. Our sizing is a relaxed version of the U.S. standardized regular fit, and most U.S. customers that have a sizing issue claim that the fit for them is on the larger side. We do advise checking our size chart or utilizing our WAIR tool, which offers automated sizing recommendations based on your measurements. We understand that sizing can vary from person to person, influenced by personal preferences and previous experiences with other brands. It's important to note that geeks come in all shapes and sizes, and we strive to cater to this diversity. It's very disheartening to receive multiple 1-star reviews from you over sizing, as we would have been more than happy to assist you with personalized sizing advice had you contacted us. We hope to have the opportunity to serve you better in the future as we're here to ensure you have the best possible experience with our products.
Perfect

This shirt is very comfortable. The fabric is soft and light, and the design quality is very good. It is perfect for warm weather and should keep you cool at the beach or by the pool.
We love the shirt! it was not the right size to fit my husband so we had to do an exchsnge for a different size, and they made the process very easy. Highly recommend this company
