Gregory Duffel Bags

Frequently Asked Questions

• What sizes do Gregory Alpaca and Supply duffel bags come in, and which models work as carry-on luggage?

  Gregory’s Alpaca line ranges from around 40L up to 100L (examples: Alpaca 40 — 22.75 x 13.25 x 11.25, Alpaca 60, Alpaca 100) and the Supply line includes a Supply 40. The Alpaca 40 and Alpaca 45L are sized for carry-on use on most airlines thanks to their ~40–45L capacity, but you should verify your carrier’s exact dimension limits before flying.
• How do the Alpaca and Supply series compare in materials, durability, and weather resistance?

  The Alpaca series uses TPU-coated recycled ripstop polyester and heavy-duty 900-denier fabric with a high-density nylon bottom for enhanced water resistance and abrasion protection, while the Supply series uses blended recycled polyester ripstop with a C0 DWR (PFAS-free) finish and a Kevlar-reinforced bottom for lightweight toughness. Alpaca models emphasize structured, weather-resistant construction (interior frames, lockable #10 YKK zippers, oversized T‑Grip pulls), whereas Supply focuses on simple, rugged utility and lower weight.
• Can I carry Gregory duffels like backpacks, and are the straps comfortable for hiking or long walks?

  Most Alpaca and Supply duffels include padded, removable backpack straps that tuck away or attach via girth-hitch, plus reinforced grab handles and internal fiberglass rods in carry straps to distribute weight. Those straps are comfortable for short hauls and moving through airports or trailheads, but they aren’t intended for prolonged backpack-style hikes with heavy loads.
• What organization and gear-separation features are built into Gregory duffels for travel and outdoor use?

  Gregory duffels commonly include a mesh-top packing cube, interior zippered mesh pockets, a wide U-zip/clamshell opening, and an expandable end pocket designed for dirty shoes or wet gear. Exterior daisy chains, ID/gear tag windows, oversized T‑Grip zipper pulls, and lockable zippers on select models further enhance lashing, identification, and security.
• How should I choose between Alpaca 40/45 and larger models like the Alpaca 60 or Alpaca 100 for multi-day trips or hauling equipment?

  Pick a 40–45L Alpaca for carry-on capability and compact weekend or short-trip packing—the Alpaca 40 is roughly 2.7 lbs and stows easily. Choose the Alpaca 60 or the 100L when you need room for multi-day gear or bulky equipment (the Alpaca 60 is heavier at about 3.38 lbs and the 100L models exceed 5 lbs); remember larger sizes trade off packability and quick shoulder comfort for increased capacity.
