What is a 4 Grade Compression Design?

Compression is the main key to consider when choosing a golf ball. 

Trust golf balls have gone through a lengthy development process, based on the PGA compression rating: Compression = 180 – (deformation x 1000).

It is based on calculating the deformation of a golf ball under 200 pounds of pressure. 

Every 0.001 inch of deformation increases the golf ball's compression rating by one point.

Balls never turned up.

Paid for balls, money was taken from my account. Waited 2 weeks balls did not arrive. Emailed them TWICE. No answer. 6 weeks later, still nothing has arrived. No response and no balls.

Trust me

Ball really suits my swing speed and I like the look and feel of them


These balls appear to cut very easily so not sure if I will be ordering again

K8 Bison series golf balls

Extremely happy with the distance obtained using the under 95 mph version. They seem to straighter too, but dead leaves don't help with the search at the moment!

@GolfNuts Review:

"Would I reccomend buying them? Absolutley."

Tour premuim quality.

Tailored to your swing speed

Get the right ball for you by choosing the right compression to match your swing speed.

What customers say:

'My drives averaged 5-10 yards longer than normal.'

I drove the golf ball longer than my usual top name brands and saw no change with any spin around the greens.

What golfers say:

I like the presentation of them! When I tried them out at the range they performed pretty well. They feel slightly lighter than my usual brand, but this seemed to have no impact on their use with driveway irons.

The colour is stellar. Very easy to identify on the golf course. Ball flight: Very good. Feel: Soft as advertised. I like the balls a lot and would have no issue buying more. These are certainly cheaper than Titleist Pro-V1's and V1x's and I would play them hands down rather than spend more on a Titleist.

Why golf ball compression is so important

Compression may be the main key to consider when choosing a golf ball. To get maximum distance, you must select the most appropriate golf ball deformation rate to match your club swing speed

If you choose the ball too hard for your swing speed, it will not compress enough to create a rebound effect. By contrast, if you choose a ball too soft, it will waste energy generated from your swing.

Performance and style

Meeting and exceeding the performance of all other premium golf ball brands


Which swing speeds are Bison Balls best for?

Trust have a dedicated range to fit your very own swing speed for maxmimum performance.

Whats the difference between K5 and K8 models?

The reactive core technology contained in the K8 is the biggest difference between both balls.

The K8 reactive core has a high response which boosts ball speed without compromising softness, increasing accuracy and maximising distance. It is designed to compete against top range models without the associated price tag.

In terms of performance, the K8 models are designed to maximise distance.

The origional K5 balls are designed to outperform all other golf ball models in the £20~30 price range.

Are they approved for competition play?

Yes, Trust Golf Balls are tour confirming to R&D and USGA standards

How do I know Trust golf balls are as good as the major brands?

In addition to being reviewed and approved by the USGA and R&A rules of golf, we had our golf balls tested by Golf Laboratories, Inc., the most respected independent golf equipment testing lab in America.

The distance, trajectory and dispersion of all Trust golf balls were found to either meet or beat the performance of premium balls from the major, name-brands.

What is unique about Bison Trust golf balls?

Our golf balls have great performance and are suitable for all golfers . Every ball we make is a premium, tour-caliber, urethane coated golf ball.

We don't make low-quality golf balls, such as surlyn-coated golf balls. 

With Trust golf balls, golfers no longer need to sacrifice mileage to get a softer hitting sensation and better performance.

If the perform so well, how are they cheaper than the big brands?

Although high quality, the price of Trust golf balls is relatively cheaper than other premium golf balls on the market.

This is because all of our products are manufactured in-house , meaning that Trust controls the entire process of making golf balls (including design, materials, core and cover). 

In addition, our products are sold directly to consumers (without going through distributors/wholesalers) so there are no additional costs to pass on to customers.
