Looking at 1-2 person tents

Ranges appear to split along the lines of 20D or lower material or 60D+, e g. Terra Nova V Wild Country

So either shortish lifespan and less durable or heavy.

Does no-one focus on 1-2 tents using 30 - 50 D materials??

What about the Alpkit Jaran 2 ? 40D I think.

Hilleberg red label tents are made from 30 D fabric, their black label 40 D.

They have several 2 person tents of either label. 

Thanks. Didn't know as their tents require a mortgage so never really gave them attention.

Macpac and lightwave both make tents in 30 and 40d fabrics. Unfortunately premium quality tents are in short supply at the moment and both these brands are quite hard to come by. 

I've noted two Terra Nova models but both are out of stock. It's definitely a problem.
