Since 1977, Gregory has built a reputation as one of the world's finest backpack manufacturers — trusted by trampers, mountaineers, and expedition teams on the highest peaks and most demanding trails across the globe. What sets Gregory apart is an obsessive focus on fit: these are packs engineered to move with your body rather than against it, using proprietary suspension systems that distribute load efficiently across long days and multi-week expeditions. Backwoods is proud to stock Gregory backpacks as part of our hiking and tramping pack range for New Zealand adventurers.
The Gregory Story — Fit First, Always
Gregory Mountain Products traces its origins to a Boy Scout project. Wayne Gregory designed his first backpack at 14, and spent years absorbing pack design knowledge and experimenting with materials in a San Diego outdoor gear shop. In 1977, he released the Cassin — an expedition-style top-loader with a revolutionary contoured profile, ergonomic hip belt, side zippers, taped seams, and an adjustable suspension that set a new standard for fit in the industry.
That first-principles approach to fit and comfort has defined Gregory ever since. The brand was the first pack maker to produce packs in multiple frame, harness, and waist belt sizes to accommodate different torso lengths and body shapes. Gregory was also the first to design a hip belt system that adjusts to different hip angles — a feature particularly important for women, whose hip geometry differs significantly from men's. Through the 1980s and 1990s, Gregory continued to innovate with new bar-tack stitches for stronger bonded webbing, lightweight ergonomic foam back panels, and advanced suspension systems that became industry benchmarks.
By 1999, Gregory had won a contract to supply the United States Special Forces with high-capacity expedition packs — recognition of the brand's engineering and durability at the highest military and professional level. Through the 2000s, Gregory packs earned Backpacker Magazine Reader's Choice and Editor's Choice awards, Outside Magazine Gear of the Year, and widespread recognition as the gold standard for fit, comfort, and performance in technical outdoor use.
Gregory Suspension Systems — Why Fit Matters
A poorly fitting pack creates fatigue, pain, and inefficient load distribution — problems that compound over miles and days on the trail. Gregory's proprietary suspension technologies solve this by allowing the pack to adjust to your specific torso length, hip angle, and body shape, and then move dynamically with you as you hike.
VersaFit Suspension
The VersaFit system — featured in Gregory's Stout (men's) and Amber (women's) ranges — uses an adjustable torso length with a perforated 3D foam breathable back panel. The torso adjustment provides 4 inches of vertical range, allowing the pack to fit a wide variety of body heights and shapes. The 3D foam back panel creates airflow channels between your back and the pack, reducing sweat buildup during hard climbs. Combined with a padded wraparound hip belt and wishbone alloy frame, VersaFit delivers stable, comfortable load management for multi-day tramping trips across New Zealand's Great Walks and backcountry routes.
FreeFloat Suspension
For larger-capacity packs, Gregory's FreeFloat system uses proprietary free-floating flex panels on the lower back panel adjacent to the waist belt. These panels allow the hip belt to pivot and flex with the natural movement of your hips and torso — creating a floating sensation on the trail where the pack genuinely moves with you rather than shifting against you. Paired with an open-air ventilated back panel, FreeFloat is the choice for expedition loads and extended backcountry trips where comfort over consecutive days is non-negotiable.
BioSync Suspension
The BioSync system is Gregory's lightest and most flexible suspension, designed for fast-and-light day hiking and trail running. Stretch-mesh shoulder harness and hip belt "tendons" wrap around your body and flex with every movement. Combined with an adjustable torso and moisture-wicking materials, BioSync delivers the fit precision Gregory is known for in a minimalist, high-output package.
Gregory Packs for New Zealand Tramping
Multi-Day Tramping Packs (35–55L)
Gregory's mid-capacity range — the Stout series for men and Amber series for women — is purpose-built for New Zealand's Great Walks and multi-day backcountry routes. These packs carry 3–5 days of food, clothing, and shelter comfortably, with features that matter on NZ tracks: a dedicated bottom sleeping bag compartment with zippered access, dual-side mesh pockets for wet gear, an integrated rain cover stored in its own pocket, and hydration sleeve compatibility. The VersaFit suspension ensures the pack fits properly and carries comfortably whether you're climbing the Tongariro Alpine Crossing or descending into the Fiordland backcountry.
Extended Expedition Packs (60–70L+)
For longer expeditions, winter alpine routes, and multi-week backcountry missions, Gregory's larger-capacity packs provide the volume and load-carrying capability required for extended self-sufficient travel. These packs excel at carrying heavy loads — up to 20–23kg (50lbs) — with suspension systems engineered to distribute that weight efficiently across your body. Essential for serious alpine tramping, thru-hiking, and any route where you're carrying more than a week of supplies.
Day Packs & Overnight Packs (20–35L)
For single-day hikes and lightweight overnight trips, Gregory's smaller packs deliver the same fit precision and build quality as the expedition range in a streamlined, lighter package. These packs work beautifully for day sections of the Great Walks, hut-to-hut tramping where you're carrying minimal gear, and any outing where you want quality without bulk.
Women's-Specific Gregory Packs
Gregory designs true women's-specific packs — not scaled-down men's designs. Women's models like the Amber series feature narrower shoulder harness spacing, contoured hip belts shaped for female hip geometry, shorter back lengths, and repositioned load lifters that account for differences in shoulder and torso proportions. These fit details mean the pack sits correctly on a woman's frame, distributes weight properly, and doesn't create pressure points or shifting during movement. For women tramping New Zealand's backcountry, a women's-specific Gregory pack is worth every cent of the investment.
Plus Size Fit Options
Gregory offers plus size versions of many pack models with extended-length shoulder straps, wider hip belts, and repositioned components like sternum straps and load lifters. These aren't simply scaled-up standard packs — they're redesigned to accommodate larger body shapes while maintaining proper load distribution and comfort. Plus size Gregory packs are priced identically to standard-fit models with no surcharge for the extended sizing.
Sustainability & Materials
Modern Gregory packs use up to 40% post-consumer recycled materials in their construction. The brand has moved away from PFAS-based DWR treatments in favor of C0 DWR formulations that deliver equivalent water resistance without the environmental impact of legacy fluorochemicals. Gregory's commitment to responsible manufacturing extends to their Limited Lifetime Warranty — a testament to building packs that last decades rather than seasons.
The Gregory Limited Lifetime Warranty
Every Gregory pack is backed by a Limited Lifetime Warranty covering defects in materials and workmanship for the life of the product. This isn't marketing — it's a genuine commitment to building packs that can be repaired and maintained across years of hard use in the field. For trampers planning multi-year adventures or simply wanting gear that lasts, Gregory's warranty provides real peace of mind.
