Fortius 1p Trekking Pole Backpacking Tent

Fortius: the name is reminiscent of "refuge" & "stronghold."  The Fortius Trekking Pole Tent is your ultimate refuge in the wild for intense adventures. Designed to surpass the limitations of traditional trekking pole tents, the Fortius is engineered to withstand the harshest conditions, from violent winds to pouring rain and lightning storms. Here's why it's the perfect companion for your rugged backcountry excursions:

  • Storm-Worthy Design: Unlike other ultralight trekking pole tents, the Fortius is truly storm-worthy. With multiple "storm points" and extra-long detachable stake lines, you have the flexibility to reinforce your shelter against the elements and pitch it in any direction, providing unparalleled protection in extreme environments.
  • Durable Nylon Construction: Crafted from durable nylon, the Fortius offers superior strength over a similar weight polyester. Our field testing has proven that minor sagging issues commonly associated with nylon can be easily resolved by retensioning the tent after initial setup, ensuring optimal performance throughout your adventure.
  • Spacious and Comfortable: Enjoy ample livable space with a large protective vestibule by the door to keep your gear sheltered and secure. Sit up fully and rest comfortably without feeling claustrophobic, thanks to the Fortius' thoughtful design that prioritizes usable space and comfort.
  • Versatile Performance: With a non-tapered bathtub floor, the Fortius can be pitched in any direction without worrying about which end you can lay your head in. The detachable storm points allow you to reinforce against wind & weather in any direction - giving you peace of mind & a better night's sleep.

Experience the full backcountry experience with the Fortius Trekking Pole Tent. With its lightweight design and durability, it's your stronghold against the elements, ensuring you stay sheltered and safe without having to sacrifice pack weight.

Not working out

Sadly, this tent isn’t going to work for me. It just isn’t designed for a humid climate. The fabric saturates and therefore doesn’t breathe. It also has some poor workmanship- a section of the screen has too much fabric and sags- looks like a cheap Walmart tent or something. The stakes I bought are also not good for eastern soil- they pull out of the ground.

Mixed feelings

I want to begin by saying that I love this tent. It is perfectly suited for what it is. The concept for ventilation is good if there is any breeze to create said ventilation. If the air is still, cool, and humid, there will be condensation. That would be the case for any tent. It set up easily. It was roomy enough for me. (I am 5'8") The tent took quite a bit of rain, and I remained dry throughout, with the exception of the interior condensation which is manageable. The vestibule is roomy enough to accommodate all of my needs. All in all, a solid product.

I like this tent because of the weight and size but during a moderate rain it did leak through the fabric

That's not characteristic of our tents. Please reach out to support@outdoorvitals.com & we'll see if we can find out what the issue is!

Love it

Used the Fortius for the first time in the Shenandoah mountains this weekend. Setup is pretty straight forward and it’s plenty of room. Nice work!

Outstanding tent!

So me and my brother and cousin went on 3 day backpacking trip. Before that when I received the tent it was going to rain that day so I set it up to practice and see if it had any leaks that I needed to fix. It was all good, it held up like a fortress lol. Absolutely love the storm point tie outs and I like how they added a backup door latch just in case your zipper fails also you can put a ridge line in the tent to hang up stuff. Very well thought out tent and it's super lightweight. Honestly to tell you the truth I don't have anything really bad to say about it. Before I bought this tent I was worried about it would sag a lot in the rain but to be honest it's not bad at all. I'm glad I just went ahead and bought it if you're on the fence about it just get it. It's a fortress!
