Item is a Lululemon Commission Men's Long Sleeve Stretch Oxfiord Fabric Button Up Shirt in River Blue Enzyme Dye. Size tag has been removed, but measurements (see pics) show this as a size 2XL. Style Code is M3DJOS. 

Shirt is in excellent gently used condition as shown, with some minor signs of being previously washed and worn, but no staining, damage, or noticeable flaws.

To save money for my buyer's, I generally use a lightweight envelope for items like this so I can ship USPS First Class/Ground Advantage. However, if you need something more quickly, I can also do USPS Priority Mail padded envelopes. Both shipping options are provided at checkout - for heavier items or West Coast destinations, I recommend checking the cost of both methods, as sometimes USPS Priority Mail can be less expensive.
