I bought this for around P350.00(?) at Second Wind Running Store Ortigas last week. Being someone who always suffered from chaffing under "there" and resorting to taping the other parts that can be saved from possible burningly-painful-post-run showers, I can say that after using this product prior to an 11km and then a 24km long run both at easy pace last week, it really works!
Another variant of this product comes with sun screen but it costs about 20-30 pesos more. The product is rather pricey but it's better than not enjoying a post-run shower.
A good buy.
