CNOC Outdoors says:
Fresh, cool, filtered backcountry water just tastes better. The Vecto allows you to easily collect, store and treat water, using your filter of choice.
The Vecto is light, durable and easy to handle. It is easy to fill with just a couple of scoops, carry to a dry camp or filter on the spot with a 42mm compatible filter. Leave more time to really enjoy your hike or just time at camp with a quick and simple filtering system.
