This feed bag is perfect for feeding horses in groups while still ensuring each horse gets their own individualized diet. Plus, the price can’t be beat! The canvas is heavy duty as described, and the bag is plenty large enough to hold a full grain meal. My horse is a bit of a hoover and had no issue adjusting to eating out of this feed bag rather than the bucket he was used to. I have not had any problems with the strap loosening while my horse is eating, and I machine washed and dried this without a problem. This is a practical and affordable feed bag that I foresee holding up to many feedings to come!
