I bought a Halfords quick-up dome tent last week, which are in their sale for half price, £45.
Didn't intend to, as i went in to buy a headlight bulb.
It doesn't have the smallest packed size but it's not too bad (33"x8"x8" sits across the panniers).
The trade off being it goes up in one/two minutes which can only be a bonus when on expedition
down the Moselle Valley and stopping at a different campsite each day.
It's sold as a 4 man which is creative advertising to say the least, but great for a bod and his kit in
comfort (I like comfort
).
Not tried it in anger yet but intend giving it an airing in spring.
(It says in the link it goes up in 10 min's, but I found this was a vast over estimate. Easily done in one/two minutes).
Worth a punt at £45.
