As one who has slept in this tent several times, I'm happy to help out in any way I can. For one, I absolutely love this tent. I've slept in it several times this year and most recently in Equador at 15,748 ft near the base of Cotopaxi. The night I had it set up, there were roughly 30-40 mph winds with gusts as high as 60 mph! The tent held up well even without guying it out.

There are several things I really like about it. One, it's super easy to set up. Two, I have full confidence that it will hold up to substantial weather (10,000mm coated floor, all guy out points are reinforced with a welded patch of durable nylon, poles (though no different than the standard Hubba) seem to hold up very well to wind, etc.). Three, I really like the interior space although some might thing it's cramped (I have plenty of room to change, but not too much room to clutter up; I'm one who only likes carrying what I need and a two person tent for one person is too much). Four, ventilation (more below). And five, the materials are the best MSR has ever used in a tent (20D x 330 thread count, nylon 66 for body and 20D x 330 thread count, nylon 66 w/ 1000 mm polyurethane @ silicone coated for the fly). The material is incredibly silky but robust.

Speaking on ventilation, there are three 'points' that have been engineered into the tent canopy. They are located on the very top of the tent, on the door at it's apex, and on the doorless side near the top similar to the door. Each of these points have a small swath of mesh (also 20D which is the lightest weight no-see-um mesh in the industry). The door has the standard two zipper sliders which allows you to zip the top slider down just a tad to allow cross ventilation when the tent door is zipped shut. The doorless side uses a 'kickstand' support (a flat, rigid but flexible plastic stiffener) that props the small vent open for cross ventilation but still allows for rain protection. The top mesh is there to allow the rising moist warm air to escape resulting in less condensation. The tent body is uncoated and I found it breaths very well. I find little difference in the standard Hubba and the Hubba HP in regards to condensation buildup.

The standard Hubba doesn't include any vent options in the fly other than the double zipper slider on the fly door. The fact that it is entirely mesh gives it great ventilation, but also means that it will have less capability of trapping heat when it's cold outside.

The upgrades of the HP are significant over the standard Hubba in my opinion. I truly believe it's one of the best one man tent options for early spring, late fall mountaineering and winter camping where heavy snow loads are not expected. The fact that CDI made it lighter than the Hubba is also a huge plus, even if only by a few ounces (Hubba - 2lbs. 13 oz. vs. Hubba HP - 2 lbs. 9 oz. (both minimum weights)). As a result I believe it's one of the most versatile, lightweight shelters on the market.

Just as a comparison, I looked up the weight of an OR Advanced Bivy and it is only 1ounce lighter than the Hubba HP (39 ounces vs. 40 ounces). Not bad!

Hope that helps. <img src="/forums/images/graemlins/smirk.gif" alt="" />
