Tents can get quite expensive, I touring on a budget so buying an expensive tent was not in the cards. So I got the Marmot Tungsten 2 on sale at REI at the time for $140, off sale it's $200, it does weigh 5 pounds but I didn't find that unacceptable for loaded bike touring. And the fabric used on this tent is a bit tougher and thus thicker and heavier than most other hiking type of tents, some reviews I read said that it could be a 3 1/2 season tent and one reviewer said he had used it in blowing snow and cold and didn't have any problems with it, I don't camp in those temps but I do know from hikers I know that thin lightweight tents aren't lasting and some leak when it rains hard, mine hasn't leaked at all. The only tent that I would buy if I wanted a lightweight tent cost around $600 from ZPacks and it uses a very tough material that lasts virtually forever and only weighs 1 1/2 pounds but the cost was prohibitive for me, so I gave up the weight in favor of keeping more money in my pocket. My hiking friend bought a $350 tent and during the first use it rained and it leaked like a sieve, he returned it to REI who sent him an upgrade tent without any extra cost, he hasn't had a chance to test that one yet, his tent weighs about 2 pounds he didn't want a tent like mine on his back.
I could have bought the Tungsten 1 which would have been lighter but I wanted the ability to bring my panniers into the tent along with whatever else I wanted, I couldn't do that with the 1, the 1 is so small it's barely enough room for one person not alone a small bit of gear and I couldn't spread out if I wanted to, so the 2 is more comfortable and accommodating.
