Decathlon (Forclaz) - MT900 Ultralight 3-person Tunnel Trekking Tent

If you are using trekking poles, the Forclaz MT900 Tarp Tent from Decathlon makes a very good argument. It is what I've been using right now and I've been pretty happy with it. 1.3kg, and properly wind tested. In any case they also have self standing (1.95kg) and tunnel (1.65kg) MT900 versions still under 300€.

The decathlon mt900 tent is pretty affordable and is almost the same as some of the MSR tents. It’s pretty light too, only downside I’d say is maybe don’t take it out in really really bad winds because the poles are pretty light. If you need smth more durable, maybe not the one. It’s roomy enough to fit two, but snugly. It’s a really nice spacious one person tent though and you can sit up fully in it

Decathlon's trek 900 series is actualy amazing for the price - their 900g down sleeping bag is around €120, their 40L pack is under 1kg for €80, and they've got those MT900 tents listed in OP's comment that are solid trekking pole shelters.
