Zpacks Nero Review

Overview

The Zpacks Nero is a 38-liter frameless roll-top pack in seam-taped Dyneema Composite Fabric. It weighs 285 g (about 10 oz), roughly what a full water bottle and a bag of tortillas weigh together. It was built for hikers whose base weight is already in single digits, and it asks them to pack carefully in exchange for almost no pack weight. Zpacks has discontinued it and replaced it with the Nero Ultra.

Performance

Weight and capacity. The Nero’s appeal is arithmetic. A conventional 55-liter framed pack can weigh two to three times as much, and the Nero’s weight advantage only holds if the gear inside it is equally disciplined. SectionHiker’s Philip Werner describes it as a pack for hikers with a base weight under about 10 lb, and puts the practical carry at 15 to 20 lb. Thru-hiker guides agree. Most hikers find it comfortable up to roughly 18–20 lb including food and water. Above that, the shoulders carry everything and the pack punishes the overload.

Carry and comfort. There is no frame. The hip belt is a webbing strap that steadies the pack rather than carrying load, and the belt can be mounted in one of three positions to suit different torso lengths. How the pack is loaded matters more than on a framed pack. Testers point out that a folded foam sit pad, sold as an optional extra at about an ounce, gives the back panel some structure. Owners who pack soft, bulky items (quilt, insulation, clothing) against the back and dense items like food in the middle get a stable carry. Those who load a bear canister or a heavy food bag get a bad one. Reviewers who have used other Neros also note that the shoulder straps are lightly padded, and that long food carries are where that shows.

Weather protection. The seam-taped DCF body is the pack’s strongest feature. SectionHiker reports it is waterproof enough that a trash-bag liner or pack cover is unnecessary. Other thru-hiker write-ups say the pack sheds rain, brushes off snow, and tolerates being set down in a puddle. DCF also doesn’t absorb water, so the pack doesn’t gain weight in a wet week. The roll-top still has to be closed properly, since it is the one place water can enter.

Layout. Pockets are minimal. There is a roll-top main bag, a long rear mesh pocket for wet layers and a tent, and two side pockets that can be reached while walking. The side pockets are solid DCF with drain holes, so they hold up better than mesh in brush. The side compression cords are non-stretch Dyneema, and a single cord does several jobs to save weight, including holding long items such as trekking poles. There are no internal dividers and no brain pocket.

Durability. DCF is strong for its weight but doesn’t resist abrasion as well as nylon. Owners who bushwhack, sit on the pack, or slide it over rock should expect wear, and the rear mesh pocket is the usual casualty. Several hikers have finished long trails with Neros, but a reviewer at The Trail Hunter still questioned how anyone gets thousands of miles from a pack this light.

Value. When it was current, the Nero was the cheaper way into a seam-taped DCF pack. One owner paid $199 for a unit in 2019, and the replacement Nero Ultra lists at $249. Used units now appear for resale well above those prices, and prices vary widely with condition.

Pros & Cons

Pros

• 285 g for 38 liters, with a waterproof body
• Seam-taped DCF means no liner or pack cover
• Solid-DCF side pockets with drain holes survive better than mesh
• Roll-top bag that compresses as gear is eaten
• Adjustable belt position fits a range of torso lengths

Cons

• Frameless, with a practical limit of about 18–20 lb
• DCF abrades more readily than nylon
• No internal organization and few pockets
• Lightly padded straps get uncomfortable on long food carries
• Discontinued, so buyers must find one used or step up to the Nero Ultra

Who Should Buy This

The Nero suits experienced ultralight hikers with a base weight under 10 lb who can keep a fully loaded pack under 20 lb. It fits three-season trips with short resupply gaps, compact kits and a quilt. It is also a strong second pack for fast overnights. Beginners, hikers carrying a bear canister, winter hikers with bulky gear, and anyone whose pack weight regularly reaches the mid-20s should look at a framed pack. People who want a current model should buy the Nero Ultra instead.

Verdict

The Zpacks Nero is a legitimate 10-ounce pack in a light, waterproof fabric, and it works well for hikers whose gear list is already pared down. Its weight limit and fabric durability are real constraints. A Nero found used at a fair price is worth buying only by a hiker who accepts those limits.
