The Mertra Hoodie: An In-Depth Overview

The Mertra Hoodie has swiftly become a go-to mid-layer for outdoor enthusiasts, commuters, and lounge-wear lovers alike. Blending technical fabrics with street-ready aesthetics, it offers warmth, mobility, and understated style in one package. This detailed note breaks down every facet of the garment—from materials and construction to styling tips—so you can appreciate what sets the Mertra apart.

Fabric Composition and Feel

Recycled Double-Knit Fleece

At the core of the Mertra Hoodie is a mid-weight, double-knit fleece spun from 67 % recycled polyester. The inner face is brushed to create a soft, lofted nap that traps warm air, while the outer face is tightly woven for abrasion resistance.

Four-Way Mechanical Stretch

Integrated elastane fibers give the fabric four-way stretch. Whether you are reaching for a bouldering hold or slinging a messenger bag over your shoulder, the hoodie flexes without restriction.

Durable Water-Repellent Finish

A PFC-free DWR treatment beads light drizzle. Although the garment is not fully waterproof, it buys you precious minutes to find shelter before moisture penetrates.

Design and Construction Details

Articulated Patterning

Instead of laying patterns flat, Mertra’s design team shaped the sleeves, shoulders, and hood to follow the natural curvature of the body. The result is a silhouette that stays smooth when you move—no bunching at the elbows, no tightness across the back.

Flatlock Seams

All major seams are joined with flatlock stitching, eliminating bulky seam allowances and minimizing chafing during high-output activities or multi-hour travel.

Laser-Cut Ventilation

Tiny perforations hidden under the arm gussets aid airflow, releasing excess heat without compromising wind resistance.

Feature Set

Scuba-Style Hood

A three-panel, contour-shaped hood hugs the head and frames the face, providing peripheral vision for cyclists and hikers. An internal cinch keeps the hood in place in windy conditions.

Integrated Neck Gaiter

When fully zipped, the collar rises above the chin, acting as a built-in gaiter. This extra coverage is invaluable on cold dawn patrols or evening walks.

Kangaroo Plus Security Pockets

The classic kangaroo pouch remains for hand warmth, but Mertra adds two invisible, zippered pockets inside—perfect for stashing keys, cards, or earbuds.

Thumb Loops

Low-profile thumb loops keep sleeves anchored under gloves, forming a continuous barrier against drafts.

Droptail Hem

A slightly elongated back panel ensures coverage when bending, biking, or sitting on cold surfaces.

Thermal Performance

Warmth-to-Weight Ratio

Lab tests show the Mertra Hoodie achieving a Clo value comparable to heavier cotton hoodies, yet at roughly two-thirds the weight. The brushed interior loft is the secret: more trapped air equals more insulation.

Moisture Management

Polyester fibers wick perspiration away from the skin and spread it across a broad surface area to evaporate quickly. This keeps microclimate humidity low, preventing that clammy feeling common in traditional sweatshirts.

Wind Resistance

The tight outer knit blocks moderate gusts. Pair the hoodie with a lightweight shell in harsher conditions for a versatile layering system.

Sustainability Credentials

Recycled Content

By sourcing post-consumer polyester, Mertra reduces dependence on virgin petroleum and diverts plastic waste from landfills.

Bluesign®-Approved Dyeing

All colorways use bluesign-approved chemical processes, guaranteeing that water discharge and worker safety meet stringent standards.

Repair-Friendly Design

Panels are cut to standard shapes, allowing easy patching or replacement by a tailor, extending the life cycle of the garment.

Fit Guide

Athletic Slim

The Mertra Mertra follows an athletic-slim profile: tailored through the torso without being compressive. Size up if you prefer a more relaxed drape or plan to layer over bulky sweaters.

Size Range

Available from XXS through 3XL, with tall options for select sizes. The elastane component means each size covers a broader span of body shapes.

Styling Suggestions

Urban Commute

Layer the charcoal model under a wool overcoat, add selvedge denim and white sneakers, and you have a polished yet comfortable city uniform.

Trail Ready

Combine the earth-tone variant with a synthetic base layer, trail pants, and a weatherproof shell tied at the pack. Swap hiking for après-hike coffee without changing clothes.

WFH Lounge

Opt for the heather gray, pair with joggers, and enjoy work-from-home days that feel like weekends—but look sharp enough for spontaneous video calls.

Care Instructions

Washing

Machine wash cold on a gentle cycle. To preserve the DWR, avoid fabric softener; it clogs the micropores responsible for breathability.

Drying

Tumble dry low or lay flat. A brief, low-heat tumble actually revitalizes the water-repellent finish.

Periodic Reproofing

After about 20 laundering cycles, refresh the DWR with a spray-on, PFC-free treatment to maintain beading performance.

Pros and Considerations

Key Advantages

Versatility: Functions as outerwear in mild weather or a mid-layer in winter.
Freedom of Movement: Four-way stretch and articulated patterning adapt to dynamic activities.
Eco-Conscious Build: High recycled content and responsible dyeing processes.

Potential Drawbacks

Not a Rain Shell: Prolonged exposure to heavy rain will overwhelm the DWR.
Slim Silhouette: Those seeking a baggy streetwear vibe may prefer sizing up.

User Feedback Snapshot
