You can't throw something you can't hold.

If the golf swing is a throw - and it is - then your hold on the club is everything.

It's the one connection between you and the clubhead you're throwing. And most golfers are trying to throw while hanging onto a grip that's too thin for them. So the hands tense up and squeeze the life out of it.

Chunky Grips are thicker than standard, with a reduced taper. That extra size does something simple and brilliant. It makes good gripping easier. You stop strangling the club and start feeling it. The tension goes, the feel comes alive, and the club is suddenly a lot easier to just throw - which is the whole game.

The grip the scientists would have designed.

This came out of my years working with biomechanists. Serious movement scientists.

When they looked at a standard golf grip, they couldn't understand why it was so thin. It made no sense to them. A thicker handle is simply easier to hold - and easier to hold means easier to throw. Golf had just never questioned it. Thin grips because thin grips, the same way it does most things.

So I made the grip the scientists would have designed. Chunky.

And here's the part I didn't expect. The reduced taper - a grip that stays thicker down toward the bottom hand instead of pinching in - has become all the rage on the major tours. Tour players have worked out what the scientists knew all along. It simply feels better. You get a great feel of the clubhead, so you can move the club the way it's meant to be moved - freely, with intent, like a weapon. When I first ordered these, I didn't even know my manufacturer already had the reduced-taper mold. When he wrote back and told me, I couldn't believe my luck.

• Considerably larger than standard grips, with reduced taper
• Half-cord - soft feel with genuine grip and traction
• A precise 72 grams each
• Based on scientific study and testing
• Full self-install instructions included

Everyone who tries a set wants one. I use them, my players use them, and the feedback is always the same. Why doesn't every club feel like this?

What you get.

I've seen grips like these sell for upwards of $30 each. That's nearly $400 for a full set. You're getting the lot for $140.

Every order is a full set of 13 grips for your whole bag - plus one extra grip, free. That bonus grip is your tester, and I genuinely recommend using it. Put it on a single club first, go and hit some balls, and dial in your ideal thickness - you can even add a little tape underneath to build it up further if you want it chunkier still. Once that one club feels just right, match the rest of the set to it. Full install instructions come with every order.
