The Arktis A192 Stowaway Shirt is available now at the Kommando Store and here is an overview video they made... "The Stowaway was designed to be as light weight as possible with a very minimalistic design. The shirt snugly fits into a little pouch located at the back of the neck and is secured with a drawstring & toggle. This can be removed if being worn with chest rigs & packs.

Similar to the level 4 PCU here in the states, it's small & lightweight enough to be thrown in a daypack, vehicle glove compartment or jacket pocket. You'll hardly notice it's there, until the weather gets rough and you need that extra layer.

The textile used is a light minirip nylon with a DWR finish, which is showerproof and highly breathable. The whole garment weighs under 200g (Based on size M).."
