  • Seedhouse SL3 is simple, efficient and classic; it's built for adventures like cross-country bike tours or those weekend peaks you've been looking to bag

  • Walls are constructed of woven nylon mesh, providing excellent ventilation and 360° views

  • All seams on tent body and fly are sealed with waterproof, solvent-free polyurethane seam tape; vestibule stormflap protects zipper from the elements
