Milk storage bag recommendations

👩‍
I need milk storage bag recommendations. I THOUHT I liked the Lansinoh ones until I started using bags from my deep freezer. I had 4 out of 7 of those leak!! When I use them from the refrigerator, I have no problems! But I'm having way too many of them leak if they come from the freezer 🙄🤦🏻‍♀️ 
Help! Which ones do you recommend that don't leak even when frozen? 
Edit: Also, each bag only has 2-4 ounces in it. Says it can hold 6 ounces so I know I'm not over-filling them 😕
