Reactor FissionSlightly more overstable than the Hex. After MVP discontinued several older mids, the Reactor is the first to be born from the ashes. The Reactor is a workhorse midrange, designed to follow any line and fill any slot in the bag. It will handle big hyzers as well as big turnovers. Tell it where to go, and it will listen. The Reactor has a "modern" midrange rim, and is the first in MVP's Next Generation of midrange discs. MVP Disc Sports Fission

Great pjs
Size: 10, Color: Under the Sea
Just what my son needed comfy tshirt & short pj combo. These are comfy and 100% cotton. I can say the quality is good after being washed a couple times but as all things the color fades. But overall these have been very useful. Definitely would buy again.

Size up
Size: 6-7, Color: Under the Sea, Size: 6-7, Color: Under the Sea
My 5 year old is at the 50th percentile for weight, and the size 6 fits him perfectly. Almost too perfectly. I wish I would’ve bought a size up, so he could grow into them. Material is soft but strong. Overall happy.

Too tight
Size: 4T, Color: Under the Sea
Very very very small. My 3yo is very skinny and the 4t it is too tight on him. Can't imagine how this would fit a less skinny kid.
