Finally ![Robert Lightfoot review photo]()
I have finally found a tank bag that doesn’t get in the way when standing up on the Triumph Tiger 800, small in size but big in uses. The bladder is a good addition meaning I don’t have to use jacket option and the size is perfect for the small shits and bits you need at hand.

Mosko gnome tank bag ![Tommy review photo]()
I did the Oregon bdr and had a couple brands of bags with me I will keep unnamed and all the zippers besides the mosko bag had issues. The mosko bag actually made my ride more comfortable on my Husqvarna 501. The bag gave me something to lean into and take weight off my shoulders and wrists when I’m just cruising. Great product I look forward to trying out other products in the future

This bag is amazing. Gave enough hydration for between stops to and from Sturgis. High quality and very versatile in mounting.

Perfect Size ![Andrew Murray, Lead Instructor with RIDE Adventures review photo]()
The Gnome Tank Bag is the perfect size on my 790R to hold water and essentials and not get in the way for agressive standing positions.
