The Otter Vortex Pro Lodge Thermal Hub Shelter features innovative technology to keep you fishing comfortably this season. The Otter Vortex Pro Lodge is built with a patented THERMALTEC 600-Denier fabric layering system that traps and retains heat, blocks wind, and shuts out light—everything to improve your success and keep you out on the ice. Featuring an exclusive Ice-Lock anchoring system, you'll enjoy a secure shelter as well as a wider base to maximize the fishable area. Additional highlights of the Otter Vortex Pro Lodge include a carrying bag, reinforced corners, and interior storage options.
