Work with houseplants 3 hours every week. I have over 25 in my own indoor patio. Was able to identify almost all the plants on my new tee shirt.
I was so delighted when I first found this tee on BecauseTees. This style was something I remembered from my childhood, fun graphic shirts that were also educational. I remember my dad had one about different insects and I always thought it was so cool. But as an adult I really hadn’t seen this style anywhere. So, I had to get it. I’m also not typically a t-shirt person, but the length, the softness of the fabric while still being durable enough to do yardwork and small house projects, and the fabulous dark green color all persuaded me that this t-shirt was the way to go. I have zero regrets and am currently eyeing the other flyway… (I love warblers and used to work at migration banding stations, so these tees are very close to my heart.) Great length. Great fit. Great design. Once I have a job I will be coming back for more.
I’ve gotten a few of these fine tees for myself as well as several close family members. Each one has represented the individual perfectly, soft and comfy, cool critters to choose from, and their purchase gives back to our very own Earth.
When I had to exchange my son’s both Howlin’ Wolf and Papa Bear tees for a different size, it was handled easily through email, efficiently and, I even feel, personally. I’ll probably get more. They’re the gift to match any character in the family!
It was a hit!!! Grandson (age 6) had asked prior if Papa would like to be called Pops!
This was a great Father’s Day gift for my husband who is a new grandfather. He absolutely loved it! It was perfect. Color was great and we love the material.
I ordered the t-shirt in a large, but it truly seems like a woman’s large so I ordered the x-large and even that seems small especially after washing it. It’s for a man that is 5’9 175 so a lathe should fit. Other than the size, we do like it, but definitely disappointed in the size
Our PopPop is thrilled to be able to wear his "most favorite job title in life" on his sleeve, so to speak. Also, the fabric is very soft.
Ordered 2 custom shirts for my husband and I, aka Gran and Pap, for a family trip! First time we wore them we got compliments! They’re so cute! They fit perfectly, the cotton is soft. They washed and dried without shrinking or getting out of shape! Loved all the color selections and were really happy with the ones we chose! Feels good ordering from a company that donates to good causes! Will definitely be recommending and ordering again!
Loved it - Perfect for my husband’s 80th birthday party theme “Life is an Adventure “. Good quality tee-shirt.
Matches my plant. The wife loves her shirt and is waiting for her matching sweatshirt.
The shift arrived and fit my boyfriend perfectly! It’s beautiful and the fabric is soft and comfortable. We haven’t washed it yet so not the shirt will hold up its shape over time, but so far I’m thoroughly pleased with the results. It’s absolutely beautiful and the orange colour is perfect.
Color and printing spot on.
But after first wash, theres a frayed thread issue
On front upper left hand shoulder.
It was cute and comfortable. I also liked the message
I gave my husband who is a “Papa” to three granddaughters, and my two sons who have two daughters and one daughter respectively these T-shirts for Father’s Day this year. They loved them -they fit great and are nice and soft. They were great Father’s Day gifts this year.!
Shirts came quickly and as expected. Love the color and the design.
Bought this for my son-it’s his first Father’s Day !
He loves it! I was worried about the fit since he is a weight lifter and quite muscular! It fit perfectly! And soooo soft!! ♥️♥️
I ordered a T-Shirt that says Pop Pop on it for Father’s Day. I was pleased with the thickness of the material and it was shipped very quickly! I also really like the original denim color’
I ordered the olive green t-shirt with the monstera print and when I opened it up, the shirt was okay but the print on the front looks like it's been through a washing machine 150 times already!! Sending it back!

Do your shirts fit true-to-size?
This is a difficult question to answer because everyone has a different body type and a different preference to what is their "ideal fit".
