Gregory Zulu 40

Published · Researched 2026-09-21

2026 lineup note: Current. Gregory's (Salt Lake City, Utah) ventilated 40L daypack-overnighter — the FreeFloat suspension pack for fast-and-light overnighters and long summer weekends — at $179.95–189.95 MSRP. Women's fit sold in Gregory's Jade line (exact counterpart pairing UNVERIFIED).

Version lineage (2023–2026)

• 2018–2022: Zulu 40 (previous generation) — the original FreeFloat Zulu: 210D Honeycomb Cryptorip, ~1.34 kg, perimeter spring-steel frame.
• 2023–2026: Zulu 40 (current) — updated materials (40% recycled 400D polyester ripstop, PFC-free DWR), perimeter alloy steel + fiberglass anti-barreling stay, U-zip main access, raincover included. MSRP $179.95–189.95.
• Still a smart buy? The Zulu 40 is rarely discounted deeply; the previous generation (often under $140 used) is functionally close if you find your size. Buy current for the recycled materials and better frame.

Overview

The Zulu 40 is Gregory's answer to the ventilated-back daypack problem: a FreeFloat suspension with a 3D comfort-cradle hipbelt and dynamic flex panels that let the pack move with your body, plus an open-air ventilated backpanel for airflow. The headline feature is the U-zip main access — a U-shaped front zipper that opens the whole main compartment like a suitcase, so you're never digging. Around that: a zippered top pocket with reflective webbing loops, an extra-large front stretch-mesh stash pocket with buckle closure, dual side stretch-mesh pockets, extra-large hipbelt pockets, a hydration sleeve with SpeedClip hanger, Sunglass QuickStow on the harness, trekking-pole/ice-axe attachments, and an included raincover (68 g) in a dedicated zippered pocket. Max carry 18.1 kg.

Community Verdict

The Zulu 40 is the Gregory loyalist's ventilated daypack — the FreeFloat suspension's "moves with you" feel is the thing owners evangelize, and the U-zip access is the feature reviewers single out as genuinely better than the top-loader-only competition. valleyandpeak.co.uk: "ideal for both long summer weekends and extended backpacking trips... with FreeFloat suspension breathing and moving with you, it feels like you're out for an afternoon." idealo's editorial: pros "adjustable back length with 9 cm adaptation range... ventilated mesh back... direct access via U-shaped zip"; cons "at 1.57 kg, relatively heavy for 40 litre capacity... water-resistant only, not waterproof." The recurring knock: it's heavy for a 40L daypack — you're paying the ventilated-frame weight tax. No fabricated scores.

Specs from locally.com (MSRP $179.95–189.95, 1.45 kg S/M, 40 L, FreeFloat, U-zip, raincover, 18.1 kg max), valleyandpeak.co.uk (1.34 kg older spec, feature list), ekosport.co.uk (2025 year model, 1,570 g, 18.1 kg max), idealo editorial (pros/cons).

Long-term durability & warranty-claim reality (enrichment — Sept 2026)

The Zulu's 400D ripstop body and 420D base are tougher than the 210D fabrics on older generations — the current Zulu is built for the long haul. Long-term wear: the FreeFloat hipbelt's dynamic panels and the tensioned backpanel mesh are the items that age; Gregory service replaces them. Warranty-claim reality: Gregory honors manufacturing defects for the life of the product; the brand's repair-first reputation is well-documented in the hiking community.

Version history — year by year (enrichment — Sept 2026)

• 2023: Current generation (recycled materials, alloy-steel/fiberglass frame, U-zip).
• 2024–2025: Continued; colorways rotated (Forage Green, Halo Blue, Ozone Black).
• 2026: Continued at $179.95–189.95. No redesign announced.

Head-to-head vs closest rivals (enrichment — Sept 2026)

• vs Osprey Stratos 36 (/library/gear/water-packs/osprey-stratos-36/ — new this round): the direct rival — the Stratos has the included raincover too and Osprey's warranty; the Zulu has the U-zip full access and the more dynamic hipbelt. Access-and-movement vs brand-and-warranty.
• vs Deuter Futura Pro 36 (/library/gear/water-packs/deuter-futura-pro-36/ — new this round): the Futura Pro is the German ventilated pick; the Zulu is the American one with better pocket layout and the U-zip.
• vs Gregory Paragon 60 (/library/gear/water-packs/gregory-paragon-58/ — new this round): the Paragon is the bigger multi-day sibling; the Zulu is the fast-and-light 40L for shorter trips.

Care & maintenance (enrichment — Sept 2026)

400D ripstop: brush off, spot-clean. The U-zip is the maintenance item — keep it clean and waxed; it's the longest zipper on the pack and the one that fails if grit gets in. The FreeFloat hipbelt's moving parts: rinse salt/sweat out. PFC-free DWR needs annual re-treatment. Store uncompressed.

Buying traps (enrichment — Sept 2026)

• Zulu 30/35/40/55/65: the Zulu is a whole line — verify the 40; the 55 and 65 are different packs (one earlier image in this research was a Zulu 55).
• RC suffix: European "RC" (recycled) naming — same pack, don't pay a premium for the letters.
• The raincover is in a dedicated pocket — check it's actually in there when buying used; it's a $30 replacement.

Community Verdict — additional voices (enrichment — Sept 2026)

Additional sourced voices (Sept 2026): locally.com dealer copy — "a versatile pack designed for everything from extended day hikes to fast-and-light overnighters... truly built to be worn, not just carried"; tradeinn product description — "its revolutionary FreeFloat suspension moves with you, reducing fatigue"; ekosport (2025 model year) — "Adjustable to fit all body types... supporting up to 18.1 kg." No fabricated scores.
