Three days of steady rain in the Cascades and StormShell didn't wet out once, on me or my pack. It's the first thing I pack now before any multi-day trek.

The Multipurpose Shell Built For Every Trail Scenario

Ripstop Built To Outlast The Trail

Thorns, branches, and rocky scrambles tear through flimsy ponchos fast. StormShell's ripstop weave shrugs off the same abuse trip after trip.

Barely There On Your Back

It compresses to fist-size and disappears into a pocket or pack pouch, not the bulky rain gear that makes every trip feel heavier.

StormShell

One Piece, Three Jobs

Wear it as a poncho, lay it flat as a ground sheet, or stake it into an emergency shelter. One true do-it-all piece instead of three separate bags.

Coated To Block Out Heavy Rain

A PU-coated ripstop weave sheds rain instead of soaking through like thin ponchos do in minutes. You stay covered through hours of steady downpour.

Based On Real and Honest Experiences

I figured a poncho would rip apart the first time I pushed through brush on a hunt, but StormShell held up through briars and branches without a single snag. It's tougher than half the rain jackets I've owned.

Marcus Bell· Verified Buyer

I laid my StormShell down as a ground tarp under the tent on a soggy forest floor and woke up completely dry. It folded back down so small I barely noticed it in my pack the next morning.

Frequently Asked Questions

Very. The PU-coated ripstop shell is fully sealed against rain, not just water-resistant. Where thin ponchos wet out and cling to your skin, StormShell keeps rain running off instead of soaking through.

Yes. StormShell is cut generously to cover you and a pack up to 50L, so your gear stays as dry as you do. Thru-hikers carrying a full pack in sustained rain rely on this the most.

It is. The ripstop weave stops small nicks from spreading into big rips, so branches, thorns, and rough trail won't leave you exposed mid-hike.

Wipe it down with a damp cloth and mild soap, then air dry fully before folding it away. No special reproofing needed, the PU coating doesn't wash off or break down with normal care.

Yes. The side press studs let you snap multiple units together for a larger ground sheet or a roomier survival shelter when you need extra coverage.

The open-sided cut and lightweight ripstop keep air moving instead of trapping it, so you skip the clammy, sweaty feeling of heavier rubber raincoats.

A rain jacket only keeps you dry while you're wearing it. StormShell doubles as a ground sheet and stakes into an emergency shelter, so one shell covers you on the move and at camp.

Spread flat, StormShell measures roughly 210 cm long by 140 cm wide, giving you generous coverage whether you're wearing it or using it as a shelter.

StormShell ships in one generous size built to fit over a wearer and a pack up to 50 liters, adjusted through the hood and hem rather than separate size options. Color and pocket-style are what varies between versions.

It compresses down to roughly fist-size inside its included carry bag, small enough to live permanently in a daypack, glovebox, or bug-out bag without adding noticeable bulk or weight.

About StormShell

StormShell is a PU-coated ripstop nylon poncho built for trail use, sized to cover both the wearer and a backpack up to 50 liters rather than just the shoulders and chest. The ripstop weave resists the small nicks and tears that spread into large rips on thinner ponchos, and the coating is fully sealed against rain rather than simply water-resistant, so it sheds a sustained downpour instead of wetting out.

Beyond wearing it, StormShell lays flat as a ground sheet and stakes down into an emergency shelter through reinforced eyelets, and side press studs let two or more units snap together for a larger shelter or covered area. The open-sided cut keeps air moving to reduce the clammy feeling of heavier rubber rain gear, and the whole poncho compresses small enough for a pocket or pack pouch.

  • Unfolds to roughly 210 x 140 cm of coverage
  • Wipes clean, no reproofing needed over time
  • Includes a matching waterproof carry bag
