It's not for lack of trying that I tested the odor control claims. I used this garment in very hot, humid conditions over 3 months. I deliberately wore it consecutive days on multi-day trips, without washing it in-between (other than an occasional rinse-down with fresh water). In all circumstances (hiking, paddling, snorkeling, running, and swimming), it delivered. That is, the lack of odor was very apparent in contrast to other garments that I have used in similar ways. I'll go so far as to say that my favorite pair of paddling shorts (which I have to treat as toxic waste after they have stewed in hot and humid conditions under my kayak skirt for consecutive days on long trips), will no longer be joining me for such trips. I will now seek garments that employ this new technology, because it really did make a positive difference to me
Fit & Comfort: The fit of this skirt, or perhaps one would call it a skort, it basically that of a spandex short. Generally I prefer a more loose-fit short for running, as I find spandex shorts tend to creep up too much for my comfort. As expected, the undershorts of the Trails Nine skirt also resulted in a slight-wedgie factor when I ran in them, so this was not my preferred activity for this garment, (even though I still continue to routinely wear it for running.)
I did find the skirt to be very comfortable for many other activities such as hiking, paddling, and swimming. The skirt is very short, so take that at face-value. It could be a positive or negative, depending on your uses and self-confidence. I drew comfort from the security of the undershorts, but it's not always apparent to others that the undershorts are there.
Adjustability: The skirt has one drawstring, which can be tied to tighten the garment around the waist. This is a standard feature of most active-wear, but I found it particularly useless in this case, as the garment is meant to fit rather skin-tight anyways. The drawstring can always be removed or just simply ignored.
Water Resistance, Breathability, Moisture-wicking: Literature on the garment states that the fabric is treated with a DWR (durable water repellant) finish, to ward off moisture from light rain and such. I deliberately got the garment soaking wet on multiple occasions (swimming, paddling, snorkeling), and I didn't really take note of transitory conditions like light rain (does'’t really happen in Miami…it’s usually all or nothing). As skimpy as the garment is, water resistance seems to me to be rather unimportant…if it's warm enough to wear the skirt, you won't care that much about water resistance and thermal control anyways. But I did note that the fabric was reasonably quick-drying and moisture-wicking. For instance, I was comfortable wearing it in a damp kayak cockpit for up to 8 hours a day.
Abrasion Construction & Durability: This garment is very durable. I've put it through the washer/dryer close to 30 times and subjected to a lot of other abuses, with no signs of wear or even fading. While hiking and swimming in the Bahamas, I came in contact with the rough limestone substrate quiet often. There were several occasions where I was sure that the skirt must have snagged and ripped on the rock during my scrambles, but I could never find any damage. The undershorts are made of a thinner material than the skirt but all are made of a quality, stretchy spandex/polyester blend.
Function/features: Other than the odor-control properties, there are few features save for the back envelope pocket and two drop-in hip pockets. I didn’t use the hip pockets (suitable mostly for gels) but did utilize the back pocket to carry my car key for daily runs (I refuse to carry much else when I'm running).
