I won't post a bunch of pictures because the other review of this shelter has a bunch of great pics. 

The Ultamid 2 is a two-person shelter, and although there is a good amount of room for two, I have used it only as a solo shelter for me and sometimes with my dog. There is a huge amount of room for one person for the weight of less than almost all solo tents. You have the pole in the middle to contend with (unless you suspend it from a tree), but head and shoulder room is abundant.

The shelter is floorless without any bug protection, but you can buy an insert that has a floor and full mosquito netting. It attaches to the inside of the shelter — at a small weight penalty and with some loss of interior head and shoulder room. I plan to use it only on fall and high mountain trips where bugs are not a problem. You do need to bring a ground cloth for your pad, but the one I use weighs less than 1 oz.

Setup — you have to choose your site carefully and it does take up a lot of room because of the floor size and the guy lines. Site selection took more time than I was used to. I used it on a JMT trip and after a while I got faster at setting it up, but it definitely requires more care and attention than say, a free-standing tent. That is a tradeoff you make for a bunch of weight savings.

I brought six snow anchors/sand anchors, which are lighter than stakes and way more useful in high mountain terrain. They are like little corded parachutes that you can fill with rocks. They worked great with the Ultamid. I also brought four stakes along. It requires a minimum of eight anchors, and can use as many as 12.

When you it set up right with solid anchors, it feels very strong and wind worthy. I didn't get much in the way of strong winds, but I am sure this shelter would be very strong if anchored well.

The pitch is actually flexible — you can vary how high off the ground the walls are. I kept them about 3-4 inches high and that worked great. In a light rain that would be no issue because you can sleep away from the wall. Even in wind driven rain you could keep the lee side elevated for ventilation. That flexibility is nice.

A great thing about Cuben fiber is that it does not absorb any moisture, so once you get the thing tightly pitched, rain or dew will not cause it to sag like nylon. I think Cuben fiber is an ideal shelter material for that reason.

I had absolutely no issues with condensation. There are two peak vents, and depending on how much of a gap you leave at the bottom, there is great airflow. In a really bad storm you would have to pitch it snug to the ground to stay dry — that might change things. But I suspect, because of the shape and size, even then condensation would be minimal.

This would be a great winter shelter. If I were to get into winter backcountry skiing again, I would get the Ultamid 4 for traveling with one or two partners. I think that would be a killer setup — especially compared to the old nine pound North Face tent I carried on those trips years ago.

It does require either two trekking poles or one pole and an extender for setup. I bought the pole extension because I don't always take two poles. It weighs about 2 oz and works perfectly with one trekking pole. By the end of my trip I could set it up in about 10 minutes when I had a good site.

The construction quality and the fittings are very high quality. All tie outs are well reinforced. You can tell the design was well thought out.

If you are not married to the idea of a floor, can deal with more creative pitching, tend to hike in bug-free areas, and want a shelter that is weather tight that provides a huge space-to-weight ratio, this is the shelter for you. It takes a bit of a different mindset than regular tents. Most people look inside, see the bare ground and want no part of it. I often take only a bivy sack, so it is a palace to me that actually weighs the same as my bivy. I am really happy with it and I'm looking forward to using again on a long trip this year.


Nice review, Paul. Thanks for posting it.

The HMG UltaMid 2 is a four-season, floor-less tent…

Rating: rated 4 of 5 stars
Source: received for testing via the Trailspace Review Corps (Sample provided by Hyperlite Mountain Gear for testing and review)


The HMG UltaMid 2 is a four-season, floor-less tent designed for the weight conscious adventurer seeking more coverage than a flat tarp without the weight of a full tent. This easy to set up, lightweight, pyramid shaped shelter is roomy inside and provides adequate protection from snow and wind.


  • Made from Cuben Fiber, a non-woven waterproof fabric
  • Completely seam sealed and reinforced
  • Waterproof door zipper
  • Lightweight
  • Line locks for perimeter staking


  • Needs to be pitched in an open, pretty level area
  • Minimum height requires two trekking poles to pitch
  • No line locks for the body tie-outs
  • Small vents

Equipment tested:

Hyperlite Mountain Gear, UltaMid 2

Key specifications from manufacturer:

  • Fully seam sealed
  • 8 perimeter tie-outs w/line locks
  • 4 body (center panel) tie outs
  • Tie out on cone for hanging the mid from a tree
  • Vents covered with no-see-um netting
  • Guy-line HMG 2.8mm Spectra core line
  • Can be pitched high off the ground or tight to the ground
  • Weight: No Guy-lines 16.6oz - With Guy-lines 17.6 (I measured the weight at 21.8oz.)
  • Width: 83”
  • Length: 107”
  • Height: 64”
  • Square Feet: 63

Shown below is a picture of what you get:


  1. Shelter
  2. Extra cordage for panel tie-outs
  3. Stuff sack

My background and conditions of use:

I am primarily a backpacker/ day hiker and live in the Pacific Northwest. My trips range from coastal temperate rain forest to high desert and alpine mountains, mostly in Oregon.

I received the shelter for testing in winter conditions and was able to get two successful snowshoe trips in. A third trip was attempted but, turned back before making camp after deciding the high wind was too much (50+ mph gusts). All testing was performed in the Mt. Hood Wilderness of Oregon.


The shelter is simple to pitch and took less than 10 minutes to complete.

Lay the shelter out, pull the four corners taut, and stake them to the ground. Since I pitched it close to the ground, I drew the perimeter tie-outs in tight before staking and then let them out several inches for adjustment before raising it.


Unzip the door, crawl in and raise the peak to the desired height with two trekking poles lashed together. It is kind of a nuisance having to lash trekking poles together but, the increased height inside the tent is nice. I used two straps to keep the poles firm, which worked pretty well.   



After the shelter has been raised, go back and draw in the perimeter tie-outs to make the make the structure more rigid.




Out in the field with the UltaMid, I also used the side and rear mid panel tie-outs. It increased stability in wind and provided more roomy feel  inside.  I also found that the shelter needs to be set up in a fairly open and level area when pitching close to the ground or shape is easily deformed and difficult to pitch taut.




The UltaMid also did well in the wind. One night when out, sustained wind was forecast to be 20 to 30 mph. The structure stayed rigid and tie-outs remained taut. I didn’t see a lot of snow, but am confident the steep pitch and slickness of the material would keep the UltaMid from collapsing in heavier snow.   

Not having a tent floor, I did have to make sure I kept track of my gear, especially small items. On the positive side though, I didn’t worry about dragging snow in or knocking snow from my boots.

Overall, the UltaMid is a very well made minimalist shelter. The Cuben fiber fabric is strong and waterproof. All the seams were sealed, has a two-way waterproof zipper, reinforced tie-outs and a snap closure on the door flaps to keep the zipper from opening inadvertently.





One thing I didn’t really get to test was the vents. I kept them closed on my trips due to the cold. They are very small and I am not sure how effective they would be in a more humid situation.  In my tests the overnight temperature was in the low 20s and I only noticed a minor amount of ice crystals that formed inside the shelter. 



In Conclusion:

As stated earlier, the UltaMid 2 is a very well built minimalist shelter that would be comfortable for two +gear and is very roomy for one.  The light weight and small packed size of the shelter helped keep my pack weight down and the amount of bulk I had to carry along with other items needed for winter travel.

I found it very comfortable to move around in due to the height and easy to get in and out of. When pitched with the mid-panel tie-outs, it is very stable and rigid against the elements. I really like the line locks on the perimeter tie-outs and wish they were added to the mid-panel tie-outs.   

My only real concern about the design is small size of the vents and how effective they are in reducing condensation under more humid conditions. Hopefully, I will be able to continue testing the shelter and can update this review at a later date.

After using a flat tarp for a few years and then using the UltaMid, I liked the ease of pitching it and having full coverage from the weather. I would recommend this type of shelter to someone looking to shed weight and reduce bulk from what they carry and still have great protection from the elements.


Nice review. I'd love to get a Cuben Fiber tarp for my hammock, but the price....WOW!

Just curious how it could be a four season tent? I use a similar tent the Shangri-la 5 by Golite and a major snow fall would collapse it. It may work in all seasons if winters are mild with little or no snow.

And my tent while heavy cost less than 1/3 the price. There are other Golite tents that are cheaper as well and weight about as much.

Just a single season in Southern, AZ… Winter! The other seasons are wrought with scorpions, centipedes, poisonous snakes and other venomous creatures. Otherwise, I would love to try a cuben fiber tent.

Gary, While I didn't get to test the tent in heavy snow conditions, the steep pitch of the shelter should keep snow from piling too high on the sides and collapsing it. I believe that is true for all tipi/pyramid shaped shelters. Using the mid-panel tie-outs also keeps the sides from sinking in. As far as the cost, Cuben fiber is a pretty specialized fabric with a very high strength to weight ratio. It was originally developed as high performance sailcloth and now making it's way out to other markets. here is a link to the manufacturers website: http://www.cubictechnology.com/technology.htm

I saw that you were unhappy there were not more line locks. There are knots that can serve the same purpose such as a taut-line or prussic. They are really simple so it seems strange to me that companies actually bother to manufacture line locks, (even though there are some clever designs.)

4 years ago

I agree that there are several knots that accomplish keeping a line taut. For the mid-panel tie-outs, I used a taut line hitch which is very effective. The reason I liked the line locks and where they were placed is that they allowed quick tightening of guy-lines and I think would work better with "dead-man" stakes in deeper snow.

The line locks I use allow me to work with tie outs without having to remove my gloves in cold weather. Nothing more miserable than trying to work with a wet/frozen tarp line in a biting wind with stiff fingers.
