Saves bags from dust and water. Key issue is that height (thickness) is low so you can't have suitcases "standing" - all the suitcases have to "lie down" (i.e the suitcase thickness is vertical) which restricts the number of suitcases you can carry on top. E.g, on my Tata HEXA, I can have 8+9 suitcases on rooftop luggage carrier normally, but with this bag, only 4 can be accommodated. If it's height could be more, it could have been a really great product.
It's the perfect solution to pack luggage on a roof rack , saves content from dust and water completely. The straps given hold everything in place without any extra ropes , Only desirable thing is better clips and cinch hold as every few 100 kms u need to tighten the straps. Overall a very good product
