As a new buyer I have found Columbia Youth PFG Finatic Short Sleeve to be a great fit for my active boy. It's light, breathable, and comfortable. As a result of using this product, I found that my SON enjoys being outside and active even more. The fabric is durable and holds up well to wear and tear .The only con is that the sizing is a bit on the smaller side, so i suggest buying one size up for a comfortable fit. Overall, a great addition to boys' fashion and activewear..See full review
