Great product

Nice yoga mat. Perfect thickness for me. Love that I can roll it up and put it out of the way. Gives great knee support and the material is comfortable.

Our grandson is beginner and we bought this set for him and he loves them. He’s 13 so he can’t drive the cart and these are light and easy to carry if he is without a cart.

Good set of clubs for beginners to find out if golf is their game! You'll need a putter, though.
Hand Orientation: Right, Color: Blue/Black
This nice inexpensive set is great for a beginner at golf, which is me--never played before. I don't evem know if I'm going to like playing, but at least I have a set of clubs so that I can give it a try...it's the exercise from walking the course that appeals to me. My son says he can teach me, even using mens clubs. I figure if I like the game, I can get a nicer set of ladies clubs and pass this set to my grandson. If I don't like the game, I can still pass the set along to my grandson! My son thought these clubs were decent weight and quality and well worth the price...the only thing missing was a putter, but we found a cheaper one to add to the set.
