They definitely help, but I have found that the DWR is never as-good-as-new again. The DWR finish can be restored with wash-in and spray-on treatments like Nikwax TX Direct Wash In. With new restrictions C8 soon taking effect, the lackluster performance of DWR will decline further. Since it is more humid outside the jacket than inside it, moisture is “pulled” through the jacket by the drier air inside. dirt, body oils, sunscreen), which causes the face fabric to become saturated with moisture. This long-chain (C8) fluorocarbon-based treatment easily degrades due to abrasion and contaminants (e.g. The Achilles heel of WP/B fabrics is the durable water repellent (DWR) treatment applied to the face fabric. It’s really just a question of timing and method. While there are measurable performance differences between the degrees of water-resistance and breathability of different fabrics, the ultimate outcome is the same: I will get wet from the outside, the inside, or both. In my experience, waterproof-breathable fabrics are neither waterproof nor breathable, especially during extended use and/or if the garment is not brand new. Think: A “waterproof” fabric does not allow moisture through it, yet a “breathable” fabric does - So how can a material be both? Why waterproof-breathable fabrics fail That “waterproof-breathable” is an oxymoron is perhaps the first clue that this fabric technology might be overhyped.

Gore-Tex, eVent, NeoShell, plus proprietary fabrics like Marmot’s Precip and Patagonia’s H2No. The outdoor industry’s solution to this body bag scenario have been waterproof-breathable fabrics (WP/B), e.g. Next time you watch a baseball game or go fishing in the rain, bring along something like the Helly Hensen Lerwick Rain Jacket.) (For low-aerobic activity, however, fully waterproof rain gear is great. polyurethane-coated nylon, silicone-impregnated nylon, or cuben fiber - the wearer would have an effective protection against external precipitation, but they would bathe in their perspiration that becomes trapped in the garment during aerobic activity. If they were to be made of the same waterproof fabric used in umbrella canopies, ponchos, tarps, and tent flies - e.g. However, their form-fitting silhouettes create a problem: near complete loss of airflow. Waterproof-breathable rain gearĪ rain jacket and pants are much more field-friendly than an umbrella or poncho. In stormier conditions at higher elevations, however, our rain jackets and pants proved to be winners. Pre-dawn start in the rain, awesome! In the mild temps, moderate humidity, and calm air at the trailhead, Peter Bakwin and I were jealous of Buzz Burrell’s airy umbrella.
#Poncho pants full
A poncho with an excellently designed hood and full arm protection? Keep dreaming. An unbreakable umbrella with a carbon fiber shaft and cuben fiber canopy? Sorry, it does not exist. I would additionally add that, probably due to limited consumer interest, there is little innovation in the umbrella and poncho space, thus curbing interest further. A poncho also struggles in high winds or when off-trail, but more importantly it leaves exposed the lower arms and legs, a major liability in cooler conditions. An umbrella is useless in high winds or when bushwhacking, snags when on poorly maintained trails, takes out of commission a hand and arm, and creates noticeable drag. Otherwise, however, they are a tough sell. These rain defenses do one thing right: They allow for excellent airflow, which helps to keep the user relatively cool (via convection) and dry (via evaporation of perspiration). But before I cover these product types in greater detail, two other options deserve mention: When hiking in the rain, the usual attire is a rain jacket and rain pants. But otherwise I bring something to help keep me dry when it rains.Ī rain jacket and rain pants are Items 10 & 11 of the Core 13, my collection of essential backpacking clothing that can be mixed-and-matched to create appropriate systems for any set of 3-season conditions. In a few instances I will leave behind my rain gear, notably short backpacking trips in dry environments when there is no precipitation in the forecast, and longer trips in hot and humid environments when a soaking is actually welcomed. Hiking in the foothills of Wyoming’s Wind River Range in the Sierra Designs Elite Cagoule Jacket, which emphasizes ventilation rather than fabric breathability.
