TheGlitchyOneI'm not sure what a "windbreaker" tent is (Does it serve double duty as a windshirt?) but the X-Mid is a high end tent built at the same factory as many premium competitors who sell tents in the $400 - $500 range. For example, the X-Mid uses premium YKK AquaGuard zippers which are rare even on $450 tents. Throughout it is using premium materials (custom coated high performance Sil/PEU poly), custom cutting edge fabrics, and hardware (e.g. ITW buckles).
As a comparison, the MSR Hubba Hubba is another 2P tent built at the same factory. It lists for $450 vs $280, so the MSR is 60% more expensive while still using basic YKK zippers versus the YKK AquaGuard ones here, plus quite likely lower cost fabrics etc. The X-Mid 2P is a strong value for what you are getting because a lot more of the money goes into actually producing the product, rather than middle men and markup. MSR likely sells the Hubba Hubba to dealers for about $250 and then it gets marked up to $450 to the customer, whereas here Drop can offer you a much lower price by selling direct to the customer. It's a strong value for what you're getting.
