Great question! Right now we carry sizes S through 3XL.
Unfortunately, our company can only offer to our customers what our dropshippers offer to us. We have to rely on what they offer (and what their suppliers offer) and as of now they tell us there is not enough demand for them to carry inventory of additional sizes.
That being said, know that this can always change in the future - we have had both requests for smaller sizes like XS and XXS and larger sizes like 4X and 5X and we do take all customer feedback into account when requesting new product!
Thank you for your patience and please continue to check the site for updates.
