anything better than a Terra Nova Zephyros (£100)

I think you’ll be pushed to beat that based on price. The Force 10 Helium tent weighs 1200g and costs ~ £160 new. A little small, but it’s a great one person tent mind.

Criteria?

How about a highlander blackthorn 1?

Comes in at 1.5kg with stock steel pegs but 1.3kg once replaced with alloy ones.

Wild Country (Terra Nova) Coshee micro. Similar to the Zephyros but with two poles so a little more sturdy and a shorted rolled pack size (which was my main criteria – from memory the Zephyros is >42cm when packed, the Coshee is about 35cm. Bought mine recently for £80.

mainly for 1-2 night solo usage and maybe the occasional wild camp.

would be nice if it could fit my daughter in too.

How many times have you pitched the coshee ed? I’d check the poles for fractures if I were you.
