If you’ve fallen in love with golf this sum­mer and are keen to im­prove your game over the win­ter, these new ul­tra-for­giv­ing clubs from Call­away could be a very good place to start.

The Big Bertha OS irons in­cor­po­rate a de­sign that Call­away has called an Exo-Cage. It is a light­weight and strong frame­work that has al­lowed Call­away en­gi­neers to dis­trib­ute yet more weight around the edges to in­crease for­give­ness.

The Exo-Cage also helps the face spring more ef­fi­ciently and closer to the le­gal lim­its for more ball speed across the face, boost­ing dis­tance.

The new con­struc­tion is joined by a wave-shaped tung­sten in­sert that low­ers the cen­tre of grav­ity (CG) to make it eas­ier for in­con­sis­tent play­ers to launch shots higher and fur­ther.

Pro­gres­sive CG po­si­tions fea­ture through the set, so weight is moved lower in each head, from the high­est­lofted to the low­est-lofted, to make the long-irons eas­ier to launch and the short-irons eas­ier to con­trol.

The Big Bertha OS irons will be joined by a match­ing hy­brid that has also been cre­ated to of­fer new lev­els of for­give­ness.

It is longer from heel to toe and deeper from front to back com­pared to tra­di­tional hy­brids, which gives you a wider area to make con­tact and more sta­bil­ity if you do miss the mid­dle of the face.

An aero­dy­namic crown de­sign then helps im­prove air­flow to en­sure the larger head doesn’t come at a cost.

To round out the hy­brid, Call­away’s Op­tiFit hosel lets you choose from eight loft and lie set­tings to re­ally fine-tune your tra­jec­tory and shot shape. Plus, you can al­ter it as you im­prove over the sea­son, too, so it al­ways does the job you need it to.

The irons come with True Tem­per Speed Step 80 steel shafts (RRP £849, seven-piece set) or UST Re­coil ES 460 graphite shafts (RRP £1,099) and are on sale from Septem­ber 30.

The hy­brid (£229) has a UST Re­coil ES 460 shaft as stan­dard, and comes in 3H (19°) to 7H (31°) lofts.
