We can’t say enough good things about our Men’s Explorer Muscle Shirt. Adding our Outback Offgrid Explorer logo to this got us excited!! Our Men’s Explorer Muscle Tee is made from a soft 100% cotton fabric so it breathes well. It is perfect for long road trips or when you are out and about enjoying life on a hot day. The 160 gsm thickness of the fabric is perfect for the Australian climate and will keep its shape for many years to come.
