How to Choose a Bag

How to Choose a Bag — Complete Guide for Luggage, Backpacks & Leather Bags

Buying a bag online is overwhelming. Backpacks, duffles, suitcases, crossbody bags — each serves a different purpose. And materials matter more than you think.

This guide covers everything you need to know — from size to material to features — so you can buy with confidence.

Step 1 — Define Your Use Case (One Bag Does Not Do Everything)

Before looking at bags, answer these questions:

  • How long will you carry it? (10 minutes across airport? All day sightseeing?)

  • What will you put inside? (Laptop? Shoes? Diapers? Suits?)

  • How often will you use it? (Daily commute? Once a year trip?)

Match bag type to use:



Use Case Best Bag Type
Weekend trip (1-3 nights) Duffle bag, weekender, 30-40L backpack
Business trip (2-5 nights) Carry-on suitcase + laptop backpack
Long vacation (5+ nights) Checked suitcase (25-30") + daypack
Daily work commute Laptop backpack, messenger bag, tote
City sightseeing Crossbody bag, sling bag, small backpack
Hiking or outdoor Daypack (20-30L) with hip belt
Parents with baby Diaper bag (many compartments)
Gym or sports Gym duffle, separate shoe compartment

Step 2 — Suitcases: Hard Shell vs Soft Shell vs Hybrid



Type Pros Cons Best For
Hard shell (polycarbonate, ABS) Protects contents, easy to clean, looks sleek Can crack, less flexible Checked bags, fragile items
Soft shell (nylon, polyester) More flexible, external pockets, lighter Less protection, can stain Carry-ons, frequent flyers
Hybrid Best of both Expensive Premium travelers

Suitcase sizes (linear inches = H+W+D):



Size Linear Inches Check or Carry-on Trip Length
Carry-on 22" or less Carry-on 1-3 nights
Small checked 24-25" Checked 3-5 nights
Medium checked 26-28" Checked 5-7 nights
Large checked 29-32" Checked 7+ nights

Airline carry-on limits (US): Most US airlines allow 22" x 14" x 9". Double-check before buying.

Step 3 — Backpacks: Size, Features, and Fit

By size (liters):



Size Capacity Best For
10-15L Daypack Kids, minimalists
16-20L Small Daily commute, small laptop
21-30L Medium Work + gym, weekend trips
31-40L Large Travel backpack, one-bag trips
40L+ Extra large Camping, extended travel

Features to look for:

  • Laptop compartment: Padded, suspended (not touching ground)

  • Water bottle pockets: Stretchy mesh on sides

  • Chest strap: Distributes weight, reduces shoulder fatigue

  • Hip belt: Essential for 25L+, transfers weight to hips

  • Clamshell opening (suitcase style): Packs like a suitcase, not a top-loading hole

  • Lockable zippers: Security for travel

For commuters: Look for luggage pass-through (strap on back slides over suitcase handle).

For hikers: Look for ventilated back panel (reduces sweat).

Step 4 — Leather Bags: Quality Matters

Types of leather:



Type Durability Price Patina Best For
Full-grain Excellent (10+ years) Highest Yes Investment pieces, work bags
Top-grain Good (5-10 years) High Slow Everyday bags
Genuine leather Fair (2-4 years) Medium No Fashion bags
Bonded leather Poor (1-2 years) Low No Avoid
Vegan/PU Fair (1-3 years) Medium No Vegan option

What we sell: Full-grain and top-grain leather options. Vegan leather clearly labeled.

Leather care tips:

  • Condition every 6 months

  • Keep away from direct heat

  • Clean spills immediately

  • Store in dust bag

Step 5 — Duffle Bags and Weekenders

Best sizes for duffles:

  • 30-40L: 1-2 nights, gym, carry-on

  • 40-60L: 2-4 nights, checked

  • 60L+: 5+ nights, road trips

Duffle features to consider:

  • Shoulder strap vs backpack straps: Backpack straps are better for longer walks

  • Shoe compartment: Keeps dirty shoes separate

  • Wet pocket: For swimsuits or toiletries

  • Structure: Structured duffles stand up; unstructured duffles pack smaller

Step 6 — Crossbody Bags, Sling Bags & Belt Bags

When to choose crossbody:

  • Sightseeing (hands-free, theft-resistant)

  • Travel days (passport, phone, wallet)

  • Evenings out (smaller than a purse)

Size guide for crossbody:



Size Fits Best For
Mini (4-6") Phone, cardholder, keys Evenings, minimal
Small (7-9") Phone, wallet, sunglasses, small camera Daily errands
Medium (10-12") Tablet, Kindle, small water bottle Work, longer days

Anti-theft features:

  • Zippers that tuck away

  • RFID-blocking pockets

  • Cut-resistant straps

  • Locking zippers

Step 7 — Diaper Bags (For Parents)

Good diaper bags are not just big. They're organized.

Must-have features:

  • Multiple compartments (no digging)

  • Insulated bottle pockets (keep milk warm/cold)

  • Changing pad included

  • Stroller straps or clips

  • Machine-washable interior (spills happen)

  • Dad-friendly design (neutral colors, not just florals)

Size: Most diaper bags are 15-25L. Big enough for diapers, wipes, bottles, change of clothes, snacks.

Step 8 — Material Quality: What to Check

Zippers:

  • YKK zippers = gold standard

  • Self-repairing zippers = better

  • Avoid plastic zippers on bags over $50

Stitching:

  • Double-stitched or bar-tacked at stress points

  • Even, tight stitches

  • No loose threads

Hardware:

  • Metal > plastic

  • Nickel, brass, or coated metal

  • Avoid painted metal (scratches)

Step 9 — Care Instructions (Make Your Bag Last)

Leather bags:

  • Condition every 6 months

  • Clean with damp cloth only

  • Store in dust bag

Nylon/polyester backpacks:

  • Spot clean with mild soap

  • Air dry only

  • Avoid washing machine (breaks padding)

Suitcases:

  • Wipe down after every trip

  • Check wheels for hair/debris

  • Store zippers partially open (reduces stress)
