Glad you two came out fairly OK.

You crashed at 85 mph off road on a Vstrom riding two up? Man, are you a former Dakar Racer?
I rode former '02 DL1000 90K miles. Rode on and off road in Baja, mainland Mexico, western USA and BC, Canada and all of California numerous times.
Tipped over a few times off road, no major crashes ... but the Strom is not a bike meant to crash well

... you are VERY lucky, IMHO, that you, girlfriend and your Strom came through OK.
Most of the top brands should give decent abrasion protection. IMO, the important factor is ARMOR worn under. Most built in Armor provides only cursory protection and is often OUT OF POSITION upon impact.
For years I've worn dirt bike style knee armor worn under my riding pants, either leathers or ADV type pants or light dirt bike pants for super hot weather. The armor to protect knees and hips goes under.
Up top I usually supplement back protection with better foam pad or a bespoke back protector. I also wear dirt bike style elbow guards as built in ones are rarely in proper position in a fall unless you jacket fits super snug. (I don't like tight fitting gear)
But even the best gear won't save you if you hit something solid or wham into an Armco barrier like I did and have your leg trapped between bike and
guard rail. Not good. Titanium plate to prove it.
Sliding down the road I've seen several top brands jackets and pants get shredded. Yes, even Rukka! (Aerostich being some of the toughest, with MotoPort right up there too)
Custom MotoPort gear, IMO, has the best protection of any gear I've seen. Custom made in So Cal.
Dainese, IMO, make some excellent gear. But many Mesh jackets will come apart in a good slide and tumble. I have a Rev' It Mesh, not crashed it but assume it will come apart. The good news is the Rev'It has good built in armor which is actually in the right place for me! (rare) But would not want to slide down pavement at 85 mph in that Mesh.
I have some nice hot weather ADV pants from Cycle Gear (in house Sedici Arturo brand) which are some of the best I've seen for the money. ($120 USD)
These pants aren't fully mesh and seem well built with just a few Mesh panels.
The KLIM gear is above average, but, IMO, way overpriced for Made In China gear. Like most riding gear, KLIM is ALL made in China. Exception is Aerostich and Motoport ...(even some Aerostich is made in China)
But IMO, brands like First Gear, Tourmaster, Alpinestar and Joe Rocket are not far off KLIM and are HUNDREDS of dollars less ... and ALL made in China. I can afford ANY jacket but ride in my trusty First Gear, my 2nd one. Fallen off many times off road. No damage to me or the jacket. Also own Alpinestar and Joe Rocket, owned Tour Master in the past.
Fieldsheer (originally a UK brand) is now a rather low budget brand, does not sell well (not promoted much)... so you see it at Fire Sale prices. Sorry to hear it let you down.
My point (finally!

) is you don't have to spend $1200 USD on a KLIM jacket to get good protection if you supplement your outfit with proper armor UNDER jacket and pants.
That is "where the human flesh meets the road". It's often that initial impact with the ground or something solid that breaks bones or damages internal organs ... as painful as Road Rash is, broken bones are worse.
Armor can save your life in a big hit. At that point the Kevlar-Cordura does not
matter that much.
