3 trees planted & a portion donated with every order
Over 1 million trees planted and $370,000 donated to Eco non-profits!

This shirt is made with sustainably grown USA cotton and sewn with USA cotton thread, so you can feel good about supporting American farmers. The garment-dyed fabric is preshrunk and soft-washed for extra comfort, and the shoulder-to-shoulder taping ensures a long-lasting fit. The double-needle stitching on the neck, armholes and bottom hem provide durability, while the ribbed collar and cuffs add a touch of style. And because the dyeing process uses 50% less water than traditional pigment dye processes on pigment dye garments, you can feel good about wearing this shirt knowing that it's eco-friendly.

This heavyweight men's shirt is a relaxed fit and fairly true to size for men. Women may want to order a size down.

We use US suppliers as much as possible, e.g., our Heavyweight100% Cotton Long Sleeve Tees are made with sustainably grown USA cotton and sewn with USA cotton thread, so you can feel good about supporting American farmers.

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". We recommend you find your favorite fitting shirt in your closet and measure from armpit to armpit. Then, take a look at our size chart listed on each individual style and compare the measurements. 

Can I return or exchange an item if it doesn't fit?

How should I care for my BeCause Tees shirt to ensure longevity?

To keep your BeCause Tees item looking its best for as long as possible, we recommend the following care instructions:

 

Machine wash cold, inside out with similar fabrics to protect the fabric and design.

Line dry or tumble dry on low to prevent shrinkage and preserve the fabric’s integrity.

 

Following these simple steps will help your item maintain its color, shape, and softness, allowing you to wear your cause proudly for years to come.

How quickly will I receive my order?

We strive to process and ship orders within 1-2 business days to get your items to you as quickly as possible.


 

During peak times, such as holidays or special promotions, production may take a bit longer — around 2-5 business days.


 

Shipping Time: Once your order is shipped, delivery typically takes 3-7 business days within the U.S., depending on your location and selected shipping option.


 

You’ll receive a tracking link as soon as your order is on its way.

Do you have an in-person store?

We hope to someday open a Bricks-and-Mortar shop, but for now, we just run out of our office/warehouse!
