Yes—the leather “lash tab” on a backpack lets you thread straps to secure small items outside the bag.
Backpacks often carry a small leather or rubber diamond with two slits on the front panel. It isn’t just decoration. That piece is a lash tab—nicknamed a pig snout. The slots act as a simple route for webbing, cord, or a short strap, so you can anchor light items on the outside of your pack without opening the main compartment.
Quick Uses You Can Trust
Below are practical ways people put a lash tab to work on commutes, day hikes, and trips. Choose soft, compact items, keep them tidy, and test for swing before you head out.
| Item | When It Helps | How To Lash |
|---|---|---|
| Rain jacket | Wet layer you don’t want inside | Roll tight; thread strap through both slits; cinch |
| Sneakers | After-gym carry home | Tie laces together; loop under strap; secure |
| Tripod | City shoots; quick access | Velcro strap through slits; add a side strap |
| Camp sandals | Let them dry while walking | Clip to a lashed cord with a mini carabiner |
| Bike light | Backup visibility | Use the light’s rubber band through the slits |
| Gloves or hat | Cold-weather stops | Mesh stuff sack + shock cord through slits |
| Trash bag | Leave No Trace on day hikes | Tie corner to cord anchored in the slits |
| Umbrella sleeve | After a sudden shower | Thread strap; keep tip pointed down |
What Are The Leather Squares On Backpacks For?
This is the exact question many shoppers type: what are the leather squares on backpacks for? The answer: utility. The tab spreads force over a reinforced patch, so a small bundle can ride outside the bag. Many packs now use rubber or TPU instead of leather. Same idea, with better water resistance. Some models add a hook-and-loop loop or a second attachment nearby to steady longer items.
Close Variant: Leather Backpack Lash Tab Uses And Limits
Lash tabs started on mountaineering packs. Climbers needed somewhere to tie odd-shaped tools. That DNA remains. Use the tab for light, awkward gear you want handy—like a rolled wind shell, a beanie, or camp shoes. Keep heavy, hard, or pointy objects inside the pack where they won’t swing, snag, or poke through fabric.
How The Two Slots Work
The slits are a path for threading. Feed a strap in one slit and out the other. The backing behind the patch spreads the load, so the face fabric doesn’t pucker. Add a small cam buckle or a friction knot, and your item stays put while you walk.
Real-World Reference Points
Outdoor brands still ship bags with working lash tabs. One snow backpack lists a “diamond lash tab … for hanging equipment,” which shows the tab’s intended function (Herschel All Season Pro). A mainstream explainer featuring a JanSport product lead also confirms that the diamond patch—formally a lash tab—exists to lash items to the outside of the pack (Reader’s Digest feature).
Strength And Weight
Think “accessory,” not “anchor.” A lash tab isn’t a haul loop. Keep each item under about 0.5–1 kg. If your pack offers a second tie-point—like a side daisy chain or compression strap—use both to reduce swing and stress.
Safe Lashing Steps
- Pick a soft, compact item that won’t poke, leak, or tangle.
- Roll or bundle it so there are no loose ends.
- Thread a strap through both slits. Add a half-twist for extra friction.
- Cinch snug, then shake the pack. If it swings, re-route or move it inside.
- Keep reflectors or lights facing outward at dusk.
History And Origin In Brief
Early climbing and hiking packs used leather tabs as simple, durable attachment points. The piece let travelers carry odd shapes—an ice tool, a mug, a wet layer—without digging into the pack. As backpacks moved into schools and cities, the tab tagged along. Some designs became decorative. Many still work as intended when paired with a short strap or cord.
Materials, Shapes, And Durability
You’ll see diamond, oval, or rectangle shapes. Leather offers a classic look and ages with use. Rubber and TPU shed water and keep a crisp shape. Laminates based on Hypalon-style sheets resist abrasion. No matter the material, neat stitching and a firm backer matter most. Without a good backer, the patch can distort the front panel when loaded.
Positioning On The Pack
Mid-panel placement is handy for balance and reach. A tab too close to the top allows long items to wag. Too low, and a lashed item can bump your legs. If your pack has a second tab or a side strap, route your lash under both contact points for a stable carry.

Use this quick guide to pick the right build and keep it in shape for years.
| Material | Best For | Care Tip |
|---|---|---|
| Full-grain leather | Classic look; daily carry | Dry wipe; occasional light balm |
| Synthetic rubber/TPU | Wet weather; school packs | Soap-and-water wipe |
| Hypalon-style laminate | Abrasion; snow packs | Rinse grit; avoid sharp bends |
| Heavy canvas patch | Retro builds | Keep dry; brush dirt |
| Molded plastic | Budget bags | Check for cracks; light loads |
| Leather over foam | Soft profile | Limit tension; keep away from heat |
| Recycled TPU blend | Travel and commutes | Wipe clean; don’t over-tighten |
What Are The Leather Squares On Backpacks For? — Use Cases That Make Sense
Use the tab when quick access beats storage. Think transit pass pouch, reflective strap for dusk walks, or a rolled wind shell. On trail, hang wet socks in sun between stops. In town, carry a compact umbrella sleeve after a cloudburst. In each case, bundle the item, keep the profile tight, and check that nothing swings into your stride.
Pair It With Other Features
Many packs offer side compression straps and short daisy chains. Thread the lash tab strap, then pass it under a side strap to add a second contact point. Two points beat one. The item rides flatter and snags less.
Care And Small Repairs
Leather tabs like the occasional wipe and a tiny dab of balm to keep fibers supple. Don’t soak. Rubber and TPU need only a damp cloth. If stitching loosens, stop lashing until it’s repaired. A cobbler or gear repair shop can restitch the patch through the original holes so the fabric isn’t weakened.
Buying Tips That Save Hassle
When you shop, tug on the tab. It should feel firm with neat, even stitching and a dense backer. Slots shouldn’t crack when bent. On leather, edges should be burnished, not fuzzy. On rubber or TPU, look for clean molding and crisp edges. If the tab sits mid-panel and you see a nearby strap or daisy chain, that’s a plus for stability.
Smart Little Add-Ons
- Short hook-and-loop strap (25–30 cm) for jackets and shoes.
- Shock cord loop with a cord lock for soft bundles.
- Mini carabiner to clip keys or a small light to a lashed loop.
- Reflective webbing strip for safer walks at night.
Safety, Etiquette, And When To Skip It
Keep exterior lashing tidy on buses and trains. Don’t bump other riders with swinging gear. In narrow aisles, carry the pack in hand. Around escalators, moving walkways, and conveyors, move exterior items inside; anything dangling can snag. In rain, don’t drip a soaked jacket onto shared seats—lash outside only until you can hang it to dry.
Clear Takeaway
That little diamond is worth using. It saves space, keeps quick-grab gear handy, and adds trail wisdom to everyday carry. The next time someone asks, what are the leather squares on backpacks for? you can point to the lash tab, show a simple strap, and secure a bundle in seconds.
