Norrona svalbard wool T-shirt is a lightweight yet durable t-shirt with a regular fit. It can be used as a stand-alone or as a layering piece. Comes with three different printed graphics. A cool feature is the interior glass wipe cloth at the bottom hem, which you can use to clean your even cooler sunglasses with. This is your first choice for the longer hikes due to its natural anti-odor properties.
