Bergans Helium 55 Review

Overview

The Helium 55 is Bergans of Norway’s long-running answer to how little pack a 55-liter load needs. It is a top-loader with a single aluminum stay, an adjustable-length back, a removable lid and a full-length front zipper, built for fast multi-day trekking and ski touring. The trade-off is familiar: it carries more than its weight suggests, but the padding and the zipper are where Bergans saved grams.

Performance

Carry. The Helium’s reputation rests on how much load it moves for the weight. Backpacker’s testers took it on big-load dayhikes and multiday trips with up to 35 pounds, and two of them chose it for a seven-day, 168-mile self-supported stage race in Arizona and Utah. They found that the stiff framesheet passed weight efficiently to a lightly padded hipbelt and shoulder straps, even on back-to-back 30-mile days. SectionHiker’s reviewer called the load transfer to the hips responsive. The aluminum stay can be pulled out and bent to match the wearer’s back, which owners with non-standard builds count as the pack’s best feature. One owner took an earlier-generation Helium on a two-week High Sierra trip at roughly 45 pounds at the start and reported that it handled the weight.

The limits show up at the contact points. A UK reviewer found the hipbelt material and padding less comfortable under a 15 kg load and called the shoulder straps slightly abrasive at times. A retailer review of the V5 also criticized comfort and the adjustment range. Bergans rates the V5 for up to 18 kg, but the pack is happiest with a total load in the low-to-mid teens of kilograms. Above that, the padding becomes the limiting factor.

Access and storage. The wide top opening is paired with a front zipper, so a sleeping bag or a buried stove doesn’t mean unpacking from the top. One owner called the zipper the feature he would never give up on a pack again. The lid floats on adjustable straps, which leaves room to wedge extra gear between lid and bag. The two stretch-mesh side pockets are big enough to swallow a sit pad or a small tent, according to Active-Traveller. There are no hipbelt pockets, so anything needed on the move goes in the lid or the side pockets.

Weather. The front zipper is the weak point. SectionHiker reported that the long zip leaks in heavy rain, so a pack liner or dry bags are a requirement in wet climates. The pack suits cold, dry conditions better. The V5’s fabric carries a PFAS-free water-repellent treatment, which helps in showers but does nothing for the zipper.

Fabric and durability. Earlier Helium generations used 100- and 210-denier Cordura, and owners called the fabric rugged where it counts. The fifth generation switched to a proprietary Nylon 66 and Black Dyneema ripstop that Bergans describes as very tough. Owners of earlier versions reported no visible damage after trips with strapped-on skis and rough rock.

Ski and alpine use. Attachment points for ice axes, poles and skis give the pack credibility on winter and alpine trips, and the compression system lets the volume shrink for shorter outings. The cord can be rigged down the sides or across the front. Reviewers found it a little fiddly to set up and prone to tangling, though they judged it worthwhile.

Choosing a Version

Two generations are in circulation, and the weight gap between them is trivial: the V5 is 923 g and the V4 is 930 g. A 7 g difference won’t show up on a trail scale. What differs is the design.

V5 (923 g). The current generation. It uses Bergans’ custom Nylon 66 and Dyneema ripstop and moves to a diagonal full-length front zipper, which Bergans lists as a change from earlier versions. Its hipbelt is removable (Bergans says it saves 165 g) and can be joined with the lid to make a small hip pack for summit pushes or camp errands. The V5 adds iliac crest relief and a pull-forward adjustment on the hipbelt, and triple-density foam in the harness. Buyers paying full price should choose this one.

V4 (930 g). The previous generation, with the same 55-liter top-loading layout and adjustable back, but without the V5’s new fabric or convertible hipbelt. It makes sense on the used market or at clearance prices, particularly for a hiker who values the stay-and-framesheet carry over the extras. At anything near V5 money, it is the weaker buy.

Pros & Cons

Pros

• About 925–930 g for 55 liters of structured, internal-frame capacity
• Carries loads of roughly 15 kg well for its weight, with adjustable torso length and a bendable stay
• Front zipper gives access to the whole bag
• Removable lid saves 70 g; the V5 hipbelt also detaches and converts to a hip pack with the lid
• Large stretch side pockets and plentiful ski, axe and pole attachment points
• Compression system lets the pack shrink for shorter trips

Cons

• Hipbelt and shoulder-strap padding is thin and grows uncomfortable under heavier loads
• Front zipper leaks in sustained heavy rain
• No hipbelt pockets
• Compression cord is fiddly to set up and can tangle
• Poor match for long carries with bulky, heavy gear

Who Should Buy This

Backpackers who want one pack for summer trekking and winter or ski-touring trips will get the most from the Helium. So will anyone who holds total load near 12–15 kg and wants more capacity and more attachment points than a typical frameless ultralight pack offers. Hikers who routinely haul heavier loads, or who need a well-padded hipbelt for big food carries, should look at a sturdier suspension. Wet-climate thru-hikers who don’t want to depend on a liner should choose a roll-top pack with no long zipper.

Verdict

The Helium 55 delivers a structured, adjustable 55-liter pack at about a kilogram, with more carrying ability than its weight implies. Buy the V5 for cold, dry or alpine trips with disciplined loads, and consider the V4 only at a real discount. Skip both if the loads run heavy or the trail runs wet.
