The Seedhouse and Taddy are two different animals. The SL2 is a super light 2 person backpacking tent. Very light materials, mesh inner and rapid erection (!)
The Taddy is a light weight 2 person backpacking/bike packing tent that’s more durable than the SL2. The materials are heavier and the tent more capable of dealing with winter conditions. The DL variant has a full nylon inner instead of the mesh inner of the standard model. This is again a bit better for winter conditions when the mesh one can be a bit draughty. I’ve had both variants and the DL is better for UK conditions.
Either tent is fantastic and very similar in size it just depends if you’re into super light backpacking (SL2) or 3-4 season ‘standard’ backpacking/bike packing (Taddy DL).
