When I wrote the Core 13 Clothing series, I was frustrated with the existing rain gear options. Manufacturers were (and still are, three years later) unquestioning of waterproof/breathable fabrics, which fall short of their hyperbolic claims; and there was little innovation in format, with everyone stuck on traditional jackets and pants.
Subsequently I was contacted by Edward Hinnant (“Cedar Tree”), who thought that I might be interested in the Packa — a hybrid rain jacket and poncho with an integrated pack cover — that he designed and distributes. I was game, of course, and he sent one over.
Since I backpack mostly in semi-arid and arid locations in the West, testing rain gear can be a challenge. But after using the Packa for three seasons — specifically, to yo-yo the Pfiffner Traverse, guide trips in California’s High Sierra, and hunt elk in Colorado — I think I can speak fairly to it.
Review: The Packa
I grade the Packa as follows:
- For innovation, A;
- For execution, C (at least for my version from late-2015, since which time it’s been improved);
- For overall performance, B.
The Packa successfully protected me (and my pack) from precip and expelled trapped heat and moisture with its generous ventilation. But I struggled with its fit and sizing, and was annoyed by some unrefined trims and details.
I found that the Packa excels most when hiking on-trail in calm weather, and in cool to warm temperatures. It seems tailor-made for conditions on the Appalachian Trail (or similar).
But when using the Packa off-trail or in high-winds, I longed for a more athletic garment that didn’t snag, flap, or drape. When it was cold and snowing, I would have preferred the warmth of a traditional shell. And in hot conditions, I believe that the only rain gear with adequate ventilation is an umbrella like the My Trail Company Chrome.
Furthermore, the Packa cannot be worn as intended (i.e. over the backpack and backpack straps) if sharp or oversized objects are attached to the exterior of the backpack, such as a trekking pole, ice axe, or snowshoes. Similarly, it cannot be worn as intended while wearing a hunting safety vest, which doesn’t have the girth to wrap around a body and backpack. In these situations, my solution was to wear the Packa under my backpack, compromising its ventilation.
My Packa is a size Medium and is made of 20d waterproof nylon. It weighs 10.0 ounces (283 g), which was consistent with the advertised weight. The seams are taped.
This fabric is no longer available. Currently, the Packa comes in two fabrics:
- 30d silicone/PU nylon (15-16 oz, $100); and,
- eVent (18-22 oz, $170).
A 15d sil-nylon version will be available around January 2019 and cost about $130, according to Hinnant. The estimated weight (9.0 oz for size Small) is attractive, but I’m unexcited about its seams, which are not taped — DIY seam-sealing is messy and time-consuming.
The 30d nylon is coated with silicone on one side and polyurethane on the other. A two-sided silicone coating would be stronger and more waterproof, but it’d be more expensive and the seams could not be taped. This 30d fabric is commonly used for tent flies and floors.
I’m generally skeptical of waterproof-breathable fabrics like eVent. Its waterproofness is compromised by abrasion, dirt, and body oils. And while its breathability is measurable, it’s insufficient to keep up with normal rates of perspiration.
I chose the waterproof/non-breathable option, for its more reliable long-term performance. It was also a rare opportunity to experiment with non-breathable rain gear.
When the Packa is closed up (i.e. zipped fully, closed pit zips, and cinched bottom hem), the build-up of perspiration inside is noticeable. In fact, it’s actually visible, due to the transparency of the fabric. My hunting partner, Steve, said that he felt clammy just looking at me, although I was more comfortable than I appeared: my fleece mid-layer buffered the moisture that had built-up.
To be fair, clamminess is a common compliant among WP/B rain jackets, too. It’s just not visible, because WP/B fabrics are opaque.
The moisture build-up was solved, however, as soon as I opened up the jacket. With help from the billowy cut, the Packa’s vents allowed relatively dry outside air to exchange with the relatively humid air inside. My damp layers even seemed to dry out with the resulting airflow — except for my lower arms, which are trapped in an un-vented zone.
The Packa is available in three sizes:
- Small (5’7″ and shorter);
- Medium (5’8″ to 6′); and,
- Large (6′ and taller).
In addition, the Medium and Large are available with extra large pack cover volume (for packs that are 65 liters or more), referred to as Medium-X and Large-X.
This 65-liter cut-off is consistent with my experience. When I used my Packa with a fully loaded Osprey Aether Pro 70, the pack cover seam was scarily tensioned. Also, the pack messed with the fit, making it impossible for me to get my arms out of the sleeves without assistance.
How does the Packa compare to more traditional options?
Versus a rain jacket
The Packa expels internal heat and moisture much better than a conventional rain jacket. Its secret is ventilation. The Packa:
- Creates an air channel between it and the user, because the Packa is worn over the backpack and backpack straps (like a poncho);
- Has an over-sized silhouette that billows with movement or wind; and,
- Features huge pit zips and an open bottom.
In this respect, the Packa is head-and-shoulders better than any jacket, even fully featured models like the Outdoor Research Foray with pit zips, side zips, and/or two-way zippers. Without an air channel between the user and the jacket, the value of these vents is limited. And “breathable” fabrics are not good enough to offset the difference.
But the Packa is unwiedly and cumbersome. The preponderance of loose, draping fabric is a liability in high winds and when off-trail, and makes it impractical for any athletic activity like running or scrambling. I often felt “lost” in the Packa, like when trying to find its arms and hood so that I could put it on, or when I wanted to adjust my pit zips or hood cinch. Product familiarity will reduce this sensation, but it will always feel more poncho-like than jacket-like.
Versus a poncho
The Packa rivals a poncho in its ventilation, but sacrifices the expected low cost and simplicity for enhanced user-friendliness, weather-resistance, and features. Unlike a poncho, the Packa has a:
- Full-length front zipper, for easy on/off;
- Full-length arm sleeves with wrist cuffs, for enhanced protection; and,
- Stiffened hood with a cinch cord.
In addition, the Packa stores more easily when not being used. Instead of taking it off entirely, it can be hung over the pack, where it’s easily accessible for rapid deployment. This is very convenient during on-and-off rain showers.
Execution and room for improvement
First, I would like to applaud Hinnant for designing an innovative option for hiking in the rain that remedies some problems of traditional waterproof/breathable jackets and pants.
But the Packa has issues of its own, some inherent to the design (mostly already discussed) and others related to the execution of it. To improve the Packa, I would recommend consideration of the changes described below. These generally are aimed at improving its finish, which currently feels cottage- or garage-level.
I have added Hinnant’s responses in italics. Some of my suggestions have been addressed over the last two years.
1. Replace the current front zipper with a shorter, smooth-sliding watertight #5 model with an easy-to-grab pull that would reduce a potential water-entry point and that would allow the user to:
- Reach the zipper without leaning over; and,
- Operate it while wearing gloves.
To retain the option of sealing flush the bottom hem, install a plastic snap.
I looked at some waterproof zippers and could not find any that were dual separating. To me dual separating is key for the front zipper. The front zipper flap now has Velcro closures to keep the flap closed.
2. Increase the height of the hood, to improve mobility and to reduce tension on the hood when the Packa is worn under a backpack. Be careful, though: more slack may cause water to pool between the shoulders and backpack.
The hood has been completely redesigned. The length has been increased and there is an adjustment added to the back of the head.
3. Reduce the size of the cord locks and the diameter of the shock cord in the hood closure, bottom hem, and pack cover. Move the bottom hem cord lock to the side, where it won’t interfere with the user’s stride.
Most of the shockcord and toggles have been reduced in size. I did leave the packcover cord and toggle big so it is easier to manage behind your head.
4. Move up the bottom hem cinch, to the base of the butt. Here, it will not restrict knee-lift. Below this higher cinch point, let the Packa drape naturally.
5. Replace the non-anchored wrist cuff cord locks with Velcro closures, which can be adjusted with one-hand and which distribute pressure more evenly than draw cords.
For about the first 7 or 8 years I used Velcro for the sleeve closures. I didn’t really like them, and they were heavy. I’ve been selling Packas 18 years now. The thought behind the shockcord closure is they allow for more air flow when opened.
6. Reinforce with heavier fabric the parts of the Packa that touch the ground when the backpack is taken off. I fear that a 20d fabric will not withstand long-term abrasion from sharp rocks and sticks if it has a 30-pound pack atop it.
I used a heavier fabric for the bottom of the packcover when I used to make Packas myself. I don’t let my Packa ever touch the ground. I take it off the pack before setting my pack down. But, point noted.
7. Move the pocket higher, so that it is more easily accessible and so that it flops less.
