Thats a great question and one I've been asked frequently. Based on my own personal experience I would say first and foremost the Mountain Pant is a must. Secondly the 90% jacket and for me the Mountain shirt. These 3 items are outstanding.
Understand that the Sitka system really is just that, a complete system designed to keep you dry, and warm without the weight of heavier clothing. With that said you need to decide what type of hunting you'll be doing. Lets say you primarily hunt November tree stands. If thats the case than you'd want to go with the 90% pants and Jacket. Especially in ND!
But if you're more of a spot and stalk September elk and deer hunter than the Mountain pant and Mountain shirt would be perfect. Also consider this. The Sitka clothing that is next to your skin IE: Summit shirt and bottoms, Zip T, etc, all contain ATB-100 silver. I don't want to bash scent blocking type clothing but if you knew the truth you'd be more apt to wear silver impregnated clothing.
So if your wearing a scent blocker type liner you may want to consider going with a silver impregnated lining system instead. But again its a matter of preference and I don't want to trash scent blocking clothing (especially when so many swear by it). But I will just say I don't wear it and I do wear ATB-100 silver lined clothing.
All in all most people eventually buy the whole system. But I understand that for many thats a big chunk of change to lay down at one time. I would strongly suggest that you look into the 90% jacket, Mountain Pants, and Mountain shirt. Than as time goes by you can add a piece here and there.
The Sitka gear products are really that good. I think as you begin to wear them you'll appreciate all that has gone into thier design and function. Jason and Jonathan (the owners and founders) are both hard core, good solid guys who both are avid Traditional bowhunters. They truly understand the demands we as hunters place upon our gear.
In a world where often you get what you pay for I'm certain you'll agree that Sitka is worth the
price.
