PDW Aegis LT 3-layer hardshell jacket in Ranger Green, water beading in spring rain

StormTek™
The Membrane

23,000mm / 21,000 g/m² — StormTek™ ePTFE

Most waterproof/breathable jackets force a trade-off: maximum waterproofness at the cost of breathability, or high breathability in a membrane that struggles in sustained rain. StormTek™ eliminates that compromise.

At 23,000mm hydrostatic head, the Aegis LT handles anything weather throws at it — sustained alpine rain, driving coastal storms, wet mountain snowpack. At 21,000 g/m²/24hr moisture vapor transmission rate (MVTR), it vents hard effort effectively, keeping you dry from the inside out during high-output activities like hiking, trail running, or technical climbing approaches.

The entire jacket is fully seam taped — no weak points, no drip-through at the shoulders or arms under load.

Shell
Construction

40D Mini-Ripstop Nylon | C6 DWR | 30D Wicking Inner Facing

The Aegis LT's face fabric is 40D mini-ripstop nylon — a deliberate choice. Many "lightweight" hardshells use 15–20D nylon to shave grams, which compromises durability against rock, brush, and pack abrasion. The Aegis LT's 40D fabric holds up in the field without crossing into expedition-heavy territory. The C6 DWR finish is applied at the face fabric to ensure water beads and rolls off rather than wetting out.

The inner facing is a custom 30D wicking polyester — actively pulling moisture away from mid-layers rather than trapping condensation against them. This matters in sustained output and sustained cold: no clammy lining, no moisture build-up against your fleece.

Cohaesive
Integrated
Components

PDW's Cohaesive™ system manages shock cords and hardware with molded nylon components in an internally routed, low-profile configuration. No external cord-locks, no hardware rattling against gear, no loose cord ends to catch. It's the kind of detail you don't notice until you use a jacket without it.

Field-Ready
Details

Purpose-Built

The Aegis LT carries several details that set it apart from standard performance hardshells:

Laser-cut loop panels on upper sleeves. Hook-and-loop compatible morale patch attachment, letting users mark their gear, express unit or community affiliation, or carry visual ID. Standard in military and law enforcement apparel; essentially absent from the civilian technical hardshell market, but included as a signature design detail in many of PDW's apparel styles to allow users to individualise their garments.

Hypalon cuff tabs. More durable than elastic or velcro closures, resistant to UV degradation and abrasion, and maintenance-free over years of use.

2-way center front zipper. Allows ventilation from below when climbing without fully opening the jacket; better temperature regulation during variable-output activity.

Full windflap behind the main zipper. No cold air infiltration through the zipper teeth.

Pockets
& Organization

Designed for the Field, Not the Trail Map

Most hardshells stop at two hand pockets. The Aegis LT goes further:

  • 2 zippered chest pockets — accessible over a pack hipbelt, large enough for gloves or a phone
  • 2 zippered upper sleeve pockets — keep essentials accessible without opening your jacket or dropping your pack
  • Interior Napoleon pocket with reinforced pen slot and electronic device wire port — your GPS unit, earbuds, or map stay organized and your cable routing stays clean
  • All pockets use YKK Aquaguard® zippers throughout — the waterproof zipper standard trusted by the technical outdoor industry

The upper sleeve pockets are the detail most buyers notice after a season of use. They're uncommon in jackets at any price point and meaningfully useful when you need fast access without disrupting layering or pack systems.

Hood
System

Articulated 3-Panel Helmet-Compatible Hood | Welded Mini-Bill | Dual Shock Cord Management

The Aegis LT's hood is helmet-cut — engineered to fit over most bump helmets, climbing helmets, and protective headgear. This isn't an afterthought; it's a decision that determines the hood's entire patterning. The articulated 3-panel construction means it moves with your head rather than fighting you, and the welded mini-bill keeps rain off your face without a floppy brim that catches wind.

Shock cord adjustment is managed via PDW's Cohaesive™ system — internally routed, with no loose cord ends or hardware clutter. Clean profile, fast adjustability, nothing to snag.

FAQ

Is the Aegis LT fully waterproof?

Yes. The StormTek™ 3-layer ePTFE membrane is rated to 23,000mm waterproofness, every seam is taped, and all zippers are YKK AquaGuard® water-resistant zippers. A full windflap backs the 2-way center front zipper.

What do the 23,000mm and 21,000g/m² ratings mean?

23,000mm is the column of water the fabric resists before leaking, which covers sustained heavy rain and wet snow. 21,000g/m² is the moisture vapor transmission rate (MVTR), meaning how much sweat vapor passes out through the fabric in 24 hours. Both figures sit at the top end of the performance range for 3-layer shells.

Will the hood fit over a helmet?

Yes. The hood is helmet cut, with dual shock cord adjustment and a welded mini bill, so it cinches down cleanly with or without a helmet underneath.

How does the Aegis LT fit, and what can I layer under it?

The Aegis LT is a regular fit with an active cut. It is sized to wear over base layers, fleece and sweaters, and the hem hits just below the waist. Available in S, M, L, XL and XXL. See the PDW sizing chart for measurements.

Is the Aegis LT an all-season jacket?

Yes. As a non-insulated shell, it works as a standalone rain and wind layer in warm months and as the outer layer of a layering system over insulation in winter.

What is the Cohaesive™ components system?

Cohaesive™ is a patented integrated cord lock system. The adjusters are built into the garment so they sit flush, with no loose toggles to snag on brush, pack straps or gear.

How should I care for the Aegis LT?

Machine wash cold on a gentle cycle with a technical wash made for waterproof fabrics, rinse well, and tumble dry on low heat to reactivate the C6 DWR finish. Avoid fabric softener and bleach.
