I have several derby hay bags. I bought these because of their good price point. Once they arrived I realized they are made of a thick nylon material with big knots which I'm not a fan of. They hold 4-5 flakes which is great. Overall if it's not used as daily hay bag it seems fine.
The size was very good and my goats have no ripped it. Would recommend
My horse ripped a huge hole in the net not even 3 days later of having the hay nets..... she ripped the top and the bottom and a part in the middle..... they shouldn’t be able to rip that easily
