Don't worry about Arktis these days, not used much anymore aside from their old chest rigs with are ally as fuck.
To start you off though, here's a good guide for anyone wanting to do a British impression.

I like the classic kits, personally there's nothing more 'SF' then getting some comfortable clothes, toss in some DPM (either trousers or a windproof) and put on your vest overtop. Like I've had hordes of different British rigs, one of my favorites being the HM Supplies chest rig. Issued rigs are top notch too, be it the assault vest, chest rig or even webbing (old but still good). If you need more info on any rigs or opinions/feedback on something that catches your eye, ask away.
Anyway, onto the classic pictures;
Civvy or P85 windproof, S95 trousers, hiking *****, PLCE OPS vest or chest rig.
Civvy shirt, 5.11 trousers, 5.11 vest or similar.
Low drag as fuck...
Tropical hat, shirt, trousers, jungle boots, PLCE webbing (balanced and worked in to user preference).
ALLY AS FUCK!
But if you wanna get a MOLLE rig for the kit...
I'll let you figure that one out
not my cup of tea...
