Product Description


The North Face Bastion 4 Tent (4-Person) 4-Season

A High Mountain Bastion of Comfort in this Tent

summit-series-logo-tnf-.jpgStorms can last for days when you're camped on a glacier or waiting for a window of clear weather to make a summit bid in the Himalayas, so a solid and bombproof tent is a must when embarking on endeavours of this calibre. Designed with input from athletes, The North Face Bastion 4 Tent is built to tolerate the kind of weather that will make you grateful that you're safely tucked away in your Bastion back at base camp. "This TNF Bastion is built for weathering the storms - whatever nature can throw at it - and it did on our trip!"

The geniuses over at The North Face were somehow able to trim some weight from the Bastion 4, but still make it stronger and more resilient to high mountain weather and mega-deep snow storms. The fly and canopy are lighter thanks to a 40D nylon material. The fly features fully sealed seams and a PU coating, giving it a hydrostatic head of 1500mm. The cut-in nylon 70D nylon floor is also PU coated and has fully sealed seams, giving it a hydrostatic head of 10,000mm.

Then TNF integrated high-low venting into the design of this double-wall tent to offer adequate ventilation to prevent moisture from accumulating along the inner wall of the tent, while the cold-crack-tested port window lets you to check on the status of the storm from the comforts of your sleeping bag. Realizing that four people and gear can get cluttered, they very wisely gave the Bastion ten interior pockets with multiple internal hanger loops to hang gear and layers from. This tent is even equipped with glow-in-the-dark zipper pulls for ease of use during still-dark alpine starts.

"I needed a tent that could stand up to torrential rains and high wind. This tent fits the bill. I opted for the TNF Bastion 4 because I like to have plenty of room for "stuff", an air mattress, and I like the headroom. It's nice to be able to sit in a camp chair without my head hitting the top while weathering out a storm. I've only had my B4 tent and footprint (sold separately) for a month and its weathered a massive storm with over 220km/h extreme winds. I felt safe, I was dry, and I slept like a baby in a tent that shrugged off that storm like it was nothing. I always stake down both the footprint and tent as well as use all support lines just in case. All I had to do was close the vents, which by the way do a pretty good job. NOW, I can see why mountain expeditions and extreme adventurers use this tent and why people have sworn by The North Face tents for many decades."      [Originally posted on]

  1. A GREAT Tent!

    Posted by Penny on 31st Aug 2018

    TNF Bastion 4 Tent: My husband and I just used this for the first time and were very happy with it. It was very humid during our trip and without the wind cover it was breathable and comfortable (I haven't used the cover yet). It is lightweight and I had no problem carrying it by myself, along with a full 40L pack, on a long hike to the campsite. I haven't found a tent (ever) that would be comfortable with the number of people it is actually rated for, but this tent was way more than enough space for the two of us to move around, change, gear, etc... My husband is 6'1 and did not feel cramped when laying down. The only thing I have had a hard time finding in a tent, was one as durable and lightweight as this that also has a vestibule without the wind cover attached. I liked how breathable the tent was without the cover but the vestibule would have been handy. As far the other pros/cons go, I wasn't able to test the waterproof or windproof features. I wouldn't say it's difficult to set up, but you do definitely need two people to do it.

  2. Pretty Impressive!

    Posted by Mountain Climber on 29th Aug 2018

    TNF BASTION 4 TENT: I needed a base camp for my mountain expeditions. Something amazing. After reading numerous reviews & my own research - the Bastion 4 came home with me. On my second trip into the mountains we had winds at the level of EXTREME (!!!), several of the guy lines snapped (admittedly, I need sturdier lines) and four of the poles bent in the three days storm. We had no rain just wind, but the tent stayed standing. The noise was deafening, my client got knocked flat by the wind when he went outside to stretch his legs. We ended up building a two foot rock wall around the upwind half of the tent to help deflect/disturb the wind current before it slammed the tent. The bent pole in the vestibule created a cup like effect that the wind grabbed on to. As a result it's almost impossible to zip the fly shut now. We splinted one of the other poles in the hopes that it would not snap and bust thru the fly. But. The tent STAYED STANDING! Several times when guy lines snapped the tent folded in on us, we added more guy lines and heavier rope and eliminated that problem. We should have prepared ourselves for that. I don't think any other tent this size would have made it thru. The extra guy lines we used came off a Hilleberg tent that had been shredded by the storm and left on the mountain as someone's trash. Ended up being our treasure. This is an amazing tent!

  3. Great Expedition Tent!
