Are you saying that these strings were on the bass from new? It's worth noting that in this case, they may have been on the bass for months before arriving at your own paws

Try a set of XT coated strings from D'Addario  

@Dood do you use them? If so what’s the lifespan like? I’m assuming you’re usually a busy man… 😁

Ive had Elixirs in the past, impressed with those.

Funnily, I've been using them on my teaching basses (thus no sweaty evenings lol) but I've recently put a set on a gigging bass rather than my usual Pro Steels. I have a gig tonight that might be a hot one, so I'll have some ideas over the weekend! 
Obviously with all the cold weather = no sweaty mits, strings have been lasting ages, but, I do have hands that kill strings quickly after long drenching 2 hour gig sets, so I'd expect a hit on string life generally.

I've been using D'addario for many years and there's certainly other brands I have used that have died significantly faster. 

Elixir are good strings, a good choice too.
