I bought this product a couple of weeks ago and I am more than happy that I bought it...
Very useful for long rides. The bag is stylish, easy to strap on, and very spacious. Earlier I had a simple waist pouch and used to struggle to take out / put back my wallet / other things while sitting on the bike. But after I got VIATERRA Thigh bag, taking things out of the bag and even putting them back has become super easy. I used to keep my cell phone else where, but now I am keeping it in my Thigh bag. The zips are smooth and easy to operate....I am yet to ride in heavy rain and so cannot comment on the waterproof effectiveness of the bag. I have used other VIATERRA products and those products have withstood the tests those are intended for and I am sure that this product will also do so....
I would recommend this product to riders or even trekkers or travelers..
