Please use this add on to add length from merino jersey collection sleeves only. Make sure to use the "customize" box for the article you are adding length onto and write in the customizations box how many inches you are adding on AND please make sure to pay for that many inches. For 5" you would add 5x 1" add on to your cart.
Please read through the description of the product before adding sleeve length. For instance, it is not possible to add length to the Alba long sleeve due to restraints of the fabric width.
