Rogen 2

Which tent are you talking about? My 2P Allak weighs a smidge over 3kg and is a geodesic, not a dome tent (a dome has two poles, hence a geodesic weighs slightly more). Yeah it’s too heavy for me to do solo hiking trips with, but when I’m with my partner, or when I’m kayak camping, it’s fine. It’s definitely overkill for summer camping though. But Hilleberg do “summer” (their Yellow Label) tents, of which there’s two dome tents: the Niak (1.6kg, but only one entrance so tricky for two people, but possible) and the Rogen (1.8kg) which are fine for almost all British weather, all year round. But the OP’s budget wouldn’t extend to a new Hilleberg anyway, so it’s not really relevant anyway 🙂 Hillebergs are worth considering if you camp a _lot_, otherwise there are plenty of more suitable options. Edit: as usual, I cannot fathom why I’m getting downvoted when I’ve posted a few basic facts here.

As the other user mentioned, Fjallraven makes good tents, and you can find them secondhand at good prices. Also, Terra Nova make good tents, and they're not as expensive as Hilleberg. You can sometimes find Hillebergs at good prices on eBay. Personally I own a couple of Hillebergs and have found them totally worth the price tag. I see them as a long term investment. But I also understand why people don't want to spend that kind of money on a tent.

While I don’t have experience with the specific tents you’re looking at, my advice would be to go with Hilleberg if price isn’t a differentiating factor. I’m sure either would work great for you - beautiful products from both companies.  I have a Slingfun Portal and I absolutely love it, but Hilleberg design is in their own class. I’ve spent probably 40-50 nights in a friend’s Hilleberg, vs. maybe 30 in my newer Slingfin, and the small details of the Hilleberg win the day. Slingfin’s design is top notch and they have great attention to detail, but Hilleberg takes the same care, attention, and no holds barred approach to quality but you know that every detail has been refined through an order of magnitude more cycles of use and abuse in absurd conditions. All the cool details that sound like a great idea on paper but don’t fully pan out in the real world have been weeded out by Hilleberg leaving an absurdly refined design.  A hardware product developer by trade, I can only aspire to that level of design quality. 

Hilleberg is solid but damn those prices hurt. If you're not doing serious mountaineering the MSR Hubba series is way more reasonable and still built like a tank

People shit on hilleberg prices till they use a hilleberg in less than ideal weather. I’ll tolerate the price for the long life and ability to handle some nasty weather. Most places in the states below tree line don’t need one though.

Came here to say this… I get the ultralight thing, but if I’m going somewhere that’s a possibility I’m just gonna take my Hilleberg.

That can happen in any tent. Happens in both of my Hillebergs.
