I have after all these but positive evaluation, this product chosen to impregnate my Iglozelt. For this I chose a sunny day (which was really), built on the tent and sprayed off. Tent completely impregnated, can still 3/4 full. After then drying the test. Water from such Bolle pearls. Can only recommend the product. Let's see how it holds in use .... but first impression Top !!!
