VIPER 640 M-9 MAINSAILWith the same shape and twist profile as the M8, the M9 introduces a high tech aramid fiber layout inside the laminate film. Aramid is a stronger fiber so not only will this 2019 World Championship winning sail give you an advantage in durability, it will stretch less in big breeze and when you wail on your control lines making the sail more controllable.

Smaller than expected
Size: Football, Size: Football
My dog likes it; but I thought it was going to be bigger than it is. It is the blue ball pictured on the right compared to a normal size soccer ball on the left.

My dog’s favorite toy and mine!
Size: Basketball
My Min Pin loves this ball! It’s durable, chewable and (my favorite) toss able in the house! Since it’s soft, it doesn’t make noise when it bounces across the floor or hits a wall or the door. Best indoor throw toy ever!

Puppy loves it! We have had hours of fun with it.
Size: Billiards
My puppy loves it! It’s soft, squishy and squeaks. I would have given 5 stars but some threads on the 8 started to come out (not completely) after a few days, but it still seems well made and we have had had many hours of fun with it.
