Telos Evo, Ikos Evo or Sentinel?

Sleeping mats and usable space
The Telos Evo floor tapers towards the feet, so compare the foot width with your mats as well as the wider head end. Contoured or tapered mats make better use of this layout. The rectangular Ikos Evo floors provide more consistent width along the sleeping area. Peak height measures only the tallest point; roof structure and wall angles also affect sitting room.
Understanding weight and weather protection
Packed weight is the useful starting point when planning what you will carry. Minimum trail weight describes a reduced setup, so check the linked product for included items and add any footprint or extra accessories you intend to carry. All models include dedicated poles.
Waterhead measures fabric resistance to water pressure. Fly and floor ratings are listed separately. Sentinel is rated 3+ season, while Telos Evo and Ikos Evo are rated 3 season.
Specifications and sources
This guide covers the eight Sea to Summit tent models listed by Ultralight Gear on 5 November 2026. Product listings are cross-checked with the manufacturer's Australian Telos Evo, Ikos Evo and Sentinel specifications and floorplans.
Floor lengths refer to the sleeping floor, rather than the larger external fly footprint. Where published figures differ, this comparison uses the manufacturer's current 134 cm Telos Evo TR2 head width, Sentinel floor areas of 2.09 / 2.86 / 3.96 m², Sentinel XP1 minimum trail weight of 1,463 g, and polyester Sentinel inner specification. Peak heights follow the Australian specification tables. Check the linked listings for current availability.
