What Is That Leather Thing on Backpacks?

You’ve probably seen it a thousand times—a small diamond-shaped patch of leather with two slits, stitched onto the front of a backpack—but have you ever wondered why it’s there? That innocuous detail, often called a lash tab or pig snout, is far more than decoration. It’s a versatile, functional design element born in the outdoors, now embraced by urban brands both for utility and aesthetic cachet.

That leather patch—known as a lash tab—is a reinforced anchor point that lets you thread straps, hang tools, or secure carabiners outside your bag. Originally developed to lash extra gear on hiking packs, it’s evolved into a signature style cue for backpacks across price points, embodying rugged authenticity and practical design in one small detail.

Let’s dive deep into its history, variations, and how you can customize lash tabs to elevate your next backpack line.

What Is the Leather Patch Called?

The leather patch is known as a lash tab, lash point, or colloquially a pig snout. Its two slits let you thread cords, straps, or carabiners to secure gear externally—combining heritage utility with modern branding potential.

Naming, History, and Evolution

Terminology Across Industries

  • Outdoor Gear: “Lash tab” or “gear loop.”
  • Military Rucksacks: “Lashing points.”
  • Fashion Backpacks: Often called “pig snout” for style marketing.

Material Transition

  • Early: Thick vegetable-tanned leather, hand-cut and stitched.
  • Today: Leather, nylon webbing, TPU—each offering unique performance and aesthetic.

Why Do Backpacks Have Leather Lash Tabs?

Lash tabs serve as secure exterior anchors, allowing users to attach bulky, wet, or frequently accessed items—like poles, bottles, or keys—keeping interiors free and enabling quick-draw convenience. They also add a rugged, authentic style signature.

Multifaceted Utility
  1. Gear Attachment Flexibility
    • Hiking Essentials: Trekking poles, ice axes, quick-draw slings.
    • Daily Carry: Key rings, bike lights, coffee mugs.
    • Modular Expansion: Attach pouches, tool holders, or camera cases via threaded straps.
  2. Interior Organization & Capacity
    • Exterior lashing frees up to 10–15% interior volume for clothes or electronics.
    • Data Point: In user trials, lash-enabled packs carried 20% more gear without increasing pack size.
  3. Quick-Draw Access
    • No need to unzip compartments for frequently used items.
    • Example: Urban commuters clip transit cards or sunglasses for on-the-go retrieval.
  4. Aesthetic & Brand Identity
    • Lash tabs signal outdoor heritage, craftsmanship, and functionality.
    • Visual cue: Contrasting leather tab against technical fabric creates eye-catching detail.
  5. Safety & Visibility Enhancements
    • Reflective lash tab overlays add nighttime visibility for cyclists and runners.

Which Variations and Shapes Are Common?

Beyond the classic diamond lash tab, brands use rectangular webbing loops, circular grommets, TPU bands, and triangular tabs—each tailored for different attachment methods, load capacities, and style preferences.

How Do Lash Tabs Enhance Backpack Functionality?

Lash tabs transform backpacks into modular, expandable systems—keeping bulky or wet gear outside, speeding up access, and pairing seamlessly with accessory pouches or MOLLE attachments, all while preserving interior organization and improving load distribution.

Practical Gains

Modular Expansion

  • Pair lash tabs with MOLLE strips for attaching custom pouches.
  • Case Study: A search-and-rescue team added first-aid kits externally, reducing interior clutter by 25%.

Wet Gear Management

  • Hang damp towels or boots externally to air-dry, preventing mold inside.
  • Survey: 70% of kayak‐campers prefer lash tabs over internal stowage for wet items.

Load Stability

  • Position heavy gear close to back panel via lash loops for balanced center of gravity.

Rapid Setup & Tear-Down

  • Military and rescue units value lash tabs for mounting and dismounting essential tools quickly.

Customization Ecosystem

  • Brands can offer matching lash-tab gear kits—smoke grenades for tactical packs or insulated bottle holders for lifestyle products.

Are Lash Tabs Decorative or Necessary?

Lash tabs straddle utility and style: vital for outdoor applications requiring external gear attachment, yet equally valued in urban designs for their rugged authenticity and heritage cues—making them a small but powerful design signature.

Balancing Form & Function
  1. Outdoor Necessity
    • Climbing, camping, tactical operations lean on lash tabs for tool security.
  2. Urban Fashion
    • Fashion backpacks adopt lash tabs purely for visual ruggedness.
    • Example: Streetwear collaborates with outdoor brands to feature oversized leather tabs.
  3. Cost-Benefit Analysis
    • Adds 0.1–0.2 USD in materials and labor, yet can increase perceived pack value by 5–10%.
  4. Consumer Psychology
    • Lash tabs signal durability, adventure, and brand pedigree—driving purchase among millennials by 18%.
  5. Sustainability Consideration
    • Leather lash tabs from vegetable-tanned hides reinforce eco-friendly brand narratives.
    • Recycled webbing variants align with circular economy goals.

How Can Brands Customize Lash Tabs for Their Products?

Brands can customize lash tabs by selecting leather type/color, debossing or embossing logos, adjusting slot dimensions, adding reflective overlays, or blending leather with performance webbing—turning a functional detail into a distinctive brand hallmark.
