Materials & Construction Built for Adventure
We constructed the Backpack of Holding from military-grade 600D polyester that resists tears, scuffs, and water intrusion during your daily quests. The fabric receives a DWR (durable water repellent) coating that causes rain and spills to bead off rather than soak through to your electronics and game books.
Reinforced stress points at the shoulder straps and main compartment zipper prevent failure even when you’re carrying a full convention haul. YKK zippers throughout ensure smooth operation through thousands of open-close cycles. The padded back panel includes breathable mesh channels that reduce sweating during long walks across campus or exhibition halls.
Capacity & Organization System
Laptop & Tech Storage
The main compartment features a suspended laptop sleeve that keeps your device floating away from the bottom of the pack, protecting it from impacts if you set the bag down hard. This padded pocket accommodates laptops from 13″ to 17″, with an elastic retention strap that prevents shifting during transport.
Gaming Gear Pockets
Two dedicated dice pockets with secure closures keep your collection organized and prevent d4s from scattering across the bottom of your ThinkGeek backpack. A flat front pocket sized for standard rulebooks or tablets includes internal organization sleeves for character sheets, pens, and miniatures cases. Side compression straps let you cinch down the profile when carrying lighter loads or expand capacity for bulkier items like hoodies or boxed games.
Comfort Features for All-Day Wear
Contoured shoulder straps distribute weight evenly across your shoulders and include dense foam padding that prevents the dreaded strap-bite even when carrying 30+ pounds of gear. An adjustable sternum strap connects the shoulder straps across your chest, transferring load away from your shoulders during extended wear.
The ventilated back panel uses a suspended mesh design that creates an air gap between the pack and your back, dramatically reducing sweat buildup during summer conventions or campus commutes. This cooling channel works in conjunction with the moisture-wicking shoulder strap fabric to keep you comfortable.

Backpack of Holding Questions & Answers
Yes, the laptop sleeve accommodates devices up to 17 inches diagonally with room around the edges. We designed it specifically for larger gaming laptops that often get squeezed into undersized pockets in other backpacks.
The sleeve measures 17.5" × 12" internally with 1.5" of padding on all sides. Even thick gaming laptops with substantial cooling systems fit comfortably without forcing or compressing the device.
Spot-clean with a damp cloth and mild soap for everyday dirt and stains. For deeper cleaning, hand-wash the empty pack in cool water with gentle detergent, then air-dry completely.
Avoid machine washing and never use a dryer, as heat and agitation degrade the DWR coating and internal padding. If water resistance diminishes over time, reapply water-repellent spray designed for outdoor gear to restore protection.
The Backpack of Holding offers 42 liters of total capacity across all compartments. At 19" H × 13" W × 8" D, it fits under most airline seats as a personal item, though we recommend checking your specific carrier's size limits.
When fully packed, the bag's structured design prevents it from sagging or bulging beyond these dimensions, ensuring it clears overhead bins and under-seat spaces without issues.
The two front dice pockets each measure 5" × 3" × 2", easily holding multiple complete polyhedral sets in standard hard cases or cloth bags. Most customers store 3-4 full sets per pocket without crowding.
The pockets include elastic loops if you prefer to organize individual dice loose, plus secure zipper closures that prevent sets from spilling even when the ThinkGeek backpack gets tossed around during travel.
Our limited lifetime warranty covers manufacturing defects in materials and workmanship – failed seams, broken zippers, detached straps, or structural failures during normal use. We'll repair or replace your pack if these issues occur.
Normal wear patterns like fabric fading, surface abrasions from heavy use, or gradual DWR coating reduction aren't covered, but we offer repair services at reasonable rates for these situations. Register your pack within 30 days of purchase to activate full warranty benefits.
The pack is designed for two-shoulder carry to properly distribute weight, especially when loaded with laptops and textbooks. Single-shoulder carry is possible for short distances when lightly packed, but the 8" depth makes it awkward for extended one-shoulder use.
If you prefer single-shoulder or crossbody carry, consider our Bag of Holding messenger-style option, which uses the same organization system in a format optimized for one-strap wear.
Every purchase includes the main pack, a removable rain cover stored in the bottom pocket, and three interior organization pouches (small, medium, large) that attach via hook-and-loop strips for cable and accessory management.
You'll also receive a printed guide mapping all pockets and suggesting optimal gear placement, plus warranty registration instructions that unlock access to our online packing tutorial library and organization tips from the ThinkGeek community.
