The Umbrella Holster allows you to keep your hands free while protecting yourself from the rain and sun with an ultralight umbrella. It easily attaches to the daisy chain on most backpack's straps. In calm weather you can keep both hands on your trekking poles, while in strong wind or driving rain you can rest one hand on the umbrella to control the angle.

The Umbrella Holster consists of a clip and an adjustable shock cord loop that attaches to your shoulder strap.

Attach the buckle above the sternum strap on your strap's daisy chain and then attach the shock cord loop at the bottom of the daisy chain.

Insert your umbrella into the clip and then cinch the shock cord tight around the umbrella’s handle.

Perfect for use with our Lotus UL Umbrella.
