I Hunted Coastal Blacktail Long Enough to Respect 20K Rain Gear

The Setup

Marine fog doesn’t announce itself. One minute you’re glassing a clearcut edge in decent light, and the next the ridgeline behind you has gone gray and soft, and you can feel that particular kind of damp that isn’t quite rain yet but has already made up its mind. If you’ve spent any real time chasing blacktail in the coast range–Northern California, southern Oregon, that whole belt of second-growth timber and alder draws–you know exactly what I’m describing. You also know what comes next.

I’ve been caught in that transition more times than I’d like to admit. Not caught unprepared, exactly. Just caught in gear that was good enough for most things and not quite enough for this specific thing. A 10K shell that breathes fine on a cold, dry climb and turns into a sauna on a wet one. A heavier jacket that handled the rain but took up half my pack and weighed my shoulders down by mile four. A packable option that compressed beautifully and delaminated by December.

Coastal blacktail country doesn’t give you a grace period. The rain comes in sideways, it stays for days, and the brush you’re pushing through is wet from the inside out. Eventually you stop compromising on rain gear. It just takes a few miserable mornings to get there.

What I Actually Found

I came into the Kings Camo XKG Stormtrek with reasonable expectations and a healthy amount of skepticism. I’ve seen "packable hard shell" used to describe gear that’s really just a glorified wind shirt with a waterproof logo on the chest. So I was watching for the gaps–where the marketing language stops and the actual performance starts.

What surprised me first was the breathability. The Stormtrek runs a 20K/20K waterproof-breathability rating, and in Kings’ price range, that’s not something I expected. Most of what I’ve tested at comparable price points is running 10K or under, which is fine for a slow, cold sit but falls apart on anything with elevation gain and sustained effort. When you’re climbing into coastal timber in October with rain coming in from the west and your heart rate up, a 10K shell turns into a greenhouse. The 20K rating on the Stormtrek actually moved enough moisture out that I wasn’t soaking myself from the inside while staying dry from the outside. That’s the balance that’s hard to find at this price.

What I expected–and didn’t get–was bulk. I kept waiting for the packability to be a compromise, for the jacket to feel flimsy or the seams to sit wrong. It compressed down to something that genuinely lived at the bottom of my pack without fighting for space with everything else. That matters when your pack is already carrying optics, layers, and whatever food you remembered to bring.

On the Product Itself

The XKG Stormtrek is Kings Camo’s newest packable hard shell, and it’s built around their Kings Windstorm Membrane–a construction that hits 20K waterproof and 20K breathability. For context: 20K means the fabric can withstand a column of water 20,000 millimeters high before it starts to leak. That’s a real number in real conditions, not a rainy-afternoon-in-the-suburbs number. It’s the kind of rating you’d expect from gear priced significantly higher, which is part of what makes the Stormtrek worth talking about.

The packable design is intentional, not incidental. It compresses small enough to disappear into a pack pocket and light enough that you stop thinking about it until you need it. For coastal hunting, that’s the right call. You’re not always going to need the shell. But when you do, you need it immediately, and you don’t want to be digging through your pack in the rain trying to find it under everything else.

The cut works well for layering–enough room over a mid-layer without being so oversized that it catches wind and billows. Hood fits over a hat without fighting it. Pockets are placed where you’d actually want them in the field.

Here’s the honest limitation, and it’s worth saying plainly: packable shells are thinner by design. That’s not a flaw, it’s a trade-off. In dense coastal brush–the kind of ceanothus and vine maple that blacktail hunters actually walk through–a thinner shell is going to show wear faster than a dedicated hard shell with heavier face fabric. If you’re running the same route through the same brush five days a week, you’ll notice it over time. It’s not a dealbreaker, but it’s worth knowing before you buy.

The Stormtrek is a Fall 2025 addition to the Kings lineup, so sizing and availability are worth confirming before the coastal season opens. I’d look at kingsoutdoorworld.com to see what they have in your size and check their current shipping options while you’re there.

Why It Fits This Kind of Hunting

Coastal blacktail hunting is not a one-gear problem. It’s a layering problem that changes by the hour. You start a morning hunt in fog that feels manageable, climb into country where the temperature drops five degrees and the wind picks up off the ocean, and by the time you’re glassing the far side of a clearcut you’re in full rain with no sign of it stopping. Then you drop back into the timber and suddenly you’re sweating again because the trees cut the wind and you haven’t slowed down.

What that kind of day demands is gear that transitions without making you stop and think about it. The Stormtrek fits that model. It’s not a dedicated sit-and-wait shell–it moves with you. The breathability rating that I mentioned earlier isn’t just a spec; it’s the difference between arriving at your glassing point in your own moisture versus arriving ready to actually hunt.

The packable format also fits the reality of how most coast range hunters move. You’re not always in the rain. You’re in the rain, then you’re not, then you are again. A shell that lives in your pack without taking up real estate is one you’ll actually have with you when the weather changes. A heavier shell that you left in the truck because it was too much to carry is useless at mile six when the fog drops.

There’s also something to be said for not treating your rain gear like a precious object. Coastal hunting is hard on gear. Knowing the Stormtrek isn’t a four-figure investment makes me more willing to use it the way it’s meant to be used–pushed through brush, sat on wet logs, stuffed back into a pack without ceremony.

One Thing Worth Knowing

Packable shells have a care requirement that most people ignore until something goes wrong. The DWR finish–the durable water repellent coating that makes water bead off the face fabric–degrades over time and especially with improper washing. When it starts to fail, the shell doesn’t leak immediately, but the face fabric wets out and gets heavy, and the breathability drops noticeably. The fix is simple: wash on low heat, tumble dry on low, and reactivate the DWR with heat. A lot of hunters wash their rain gear like it’s a flannel shirt and then wonder why it stopped working.

With the Stormtrek specifically, I’d also say don’t size down for a trim fit if you’re planning to layer under it. The packable construction doesn’t have a lot of extra room built in, and a shell that’s too snug over a fleece mid-layer restricts movement in ways you’ll notice on a long climb.

The thing I haven’t fully resolved–and I’m not sure I need to–is whether I’d reach for this jacket if I were hunting the same country five days a week through a full November. I think I’d want something with heavier face fabric for that kind of sustained use. But for the way I actually hunt, it’s the right tool. Whether that distinction matters to you depends on how you hunt.

If You’re Curious

I use the Stormtrek when I need a shell that earns its place in the pack rather than just riding along. Coastal blacktail mornings, coast range elk country, any situation where the weather is genuinely unpredictable and I’m moving enough to care about breathability. I don’t reach for it when I know I’m going to be stationary for hours in a downpour–that’s a different kind of shell for a different kind of day.

If you’re hunting similar country and you’ve been making do with something that’s almost good enough, it’s worth looking at what Kings has available right now at kingsoutdoorworld.com. The Stormtrek is new this fall, sizing moves, and free shipping thresholds can make the decision easier than you’d expect.

Beyond that, I’d just say: stop compromising on rain gear. The coast range will find every gap in your kit eventually. Might as well get ahead of it.
