Does this tent require seam sealing?

  • No, this tent is fully waterproof from the factory.

Do I need trekking poles?

  • Yes, or we have substitute poles that are available for purchase separately.

Can this tent be freestanding?

  • No, this tent is a non-freestanding trekking pole tent.

Does this tent accommodate tall people?

  • We recommend this tent for people up to 6 ft 6 in / 1.98m. 

Is this tent stuffable?

  • We highly recommend folding and/or rolling the tent and not stuffing it to extend the UltraTNT fabric lifespan, but the carbon fiber struts are easily removed from the fly.

Are there additional tie-out points for extra staking?

  • Yes, this tent comes with apex lines pre-attached, and there are tie-out points along the perimeter hem. Door ties can also double as tie-out points. 

Which interior type should I get?

  • The full solid interior is recommended for colder conditions. Solid interiors block wind and trap warm air, but obscure the view from inside the tent. 
  • The mesh interior is recommended for warm and/or humid conditions. Mesh interiors allow for maximum ventilation, which helps minimize condensation. The mesh is also transparent and allows you to see out of the tent. 

Do I need a groundsheet?

  • Maybe. Use of a groundsheet depends on the ground conditions and floor type selected. Our 15D quadruple ripstop nylon floors are more durable than most ultralight tent floor options, but a groundsheet is recommended for use on highly abrasive and/or sharp ground, such as on sandstone or when pitching on sharp rocks.

How do I avoid condensation?

  • ALL tents suffer from condensation in the right/wrong conditions, but there are steps you can take to limit it. Try to avoid camping overnight in cool, damp environments such as river valleys, meadows, marshes, and next to water. If possible, choose an elevated campsite with a bit of a breeze and preferably under a tree canopy.  Please refer to the Choosing a Better Campsite video to better understand how to avoid condensation.

The StratoSpire 2 Ultra was launched in 2023, but the StratoSpire design dates back 2011.

    Amazing tent, this was my first light weight tent and after using it every weekend since I got it, I have to say it has definitely become a tough decision between it and my hammock that I’ve been using for many years.
