Although I didn't order a hoodie, the quality of the t-shirt I bought was very good.

The quality of the material was good on the hoodies I bought, very soft and warm without the fabric being too heavy but the printing was absolutely horrible and the prints on both of my hoodies washed out almost immediately. Now I have two soft, warm, entirely useless hoodies that look like garbage and they cost me over $100.

I only ever ordered a t-shirt, phone case, and sheet of stickers from them, so I cannot give a negative or positive about a hoodie specifically. With the shirt though, the fabric was really soft and comfortable, so I assume hoodies would be the same standard of quality.
Like William said though, it's hard to judge the quality of the image, as it depends on the picture the artist used. Like, my phone case looks amazing, but my stickers are kinda sloppy and look fairly pixelated.
If you order and are unhappy though, redbubble seems has awesome customer service and they seem like they are more than happy to work with customers to make them happy

I was disappointed with my order. It was a t-shirt. I ordered one size bigger, was to big in chest area, tight in the stomach and arms. The print was off-centered as well. The material is very soft so I kept it and used it for pj's. Unfortunately I won't be ordering again with Redbubble. The hoodies may be different. Good luck!

The quality is great. I had to originally reorder since my item was a little big. They sent me a new one at no cost. Wonderful customer service

Watch some youtube reviews, thats what i do... quality of shirts have felt different to me at times but i cant say for hoodies since i have never ordered one, they are so expensive

I only ordered a poster. But what i got was exactly what i ordered! Its a great place in my opinion. I was worried after the reviews i read too. But not anymore!

The quality of the print depends on the resolution that the artist uploaded to begin with. Usually it is pretty good or the product would not be offered. The material is good. Redbubble has a 100% money back guarantee so go ahead and order.
