Six Moon Designs - Skyscape Trekker

Specifics would help. How "severe"? Wind and water resistant are attributes of most tents. Less weight may mean DCF so increased cost. Tarptent makes many quality models. Hilleberg is heavy but a standard for extreme cold, snow & wind conditions. My Six Moons Design Skyscape Trekker survived many high winds, hail storms, 6" of snow and sub freezing temps.

If you can stretch the budget, GG The One is basically the very lightest non-dcf full tent at 17oz w/o stakes (it can take up to 9 lol) 255 dollars already seam sealed. I grabbed one on sale as I’d been eyeing it for a while because of the weight:cost ratio. It has its own drawbacks but I could not resist the 17oz weight. I did a write up a while back on the skyscape trekker, which is the same as the scout, just using a lighter material: https://www.reddit.com/r/Ultralight/s/hHVbwZ93NM The Trekker is 32oz and the scout is 40oz (to freedom!!) Tarp could work. I just got a bunch of ticks so I’m saving the tarp for a different environment/elevation/weather. GG Twinn? Gatewood cape? Anyway, there is no one answer as you can see. A 40oz tent could still be part of a sub 5kilo base if you are careful. ETA in my shopping experience a tarp+bivy, (like full bug inner with floor) while awesome and versatile, is scantly less weight/expense than modern tents.

I brought my Six Moon Designs on a PCT thru hike and absolutely loved it. If you plan on backpacking and use trekking poles, it's a great choice. If you're doing more car camping, I have a cheap pop-up tent from Amazon for that and it sets up in about 1 minute. For car camping, the easier the better IMO.
