I bought this at the end of summer last year, so I had it for fly season this year. I decided on the 'Black Ice' color, which looks great on my chestnut horse. The 78" runs true to size and fits my horses length and chest perfect. He has no rub marks on his shoulder or chest at all! First I was afraid it would be to hot for our humid Pa summers, but my horse didn't sweat at all! My horse also goes out at least 12 hours a day if not more with numerous heard mates. It's now September my horse has worn this all summer and it has one tiny hole started. He will be able to wear it again next summer. I will also add that I like if it gets dirty I just take a brush and it comes right off. The only thing I would change is more adjustment in the belly surcingle straps-I have them as small as they will go and they still could go down a little bit more-other than that I love it-and would highly recommend it!
