Forclaz Trek 100 Easyfit 50L Review

Overview

The Forclaz Trek 100 Easyfit is Decathlon’s mid-range trekking pack, built around a patented automatic back-length adjustment system that promises a dialed-in fit without the usual fussing with torso-length sliders. This men’s 50L pack is designed for several days of trekking in the mountains and is big enough to store everything you need for a trouble-free journey. At around $119, it’s aimed squarely at budget-conscious hikers and first-time backpackers who want a legitimate suspension system without paying Osprey prices — though the 1,588g (3.5 lb) empty weight means committed ultralight folks should look elsewhere first.

Performance

The Easyfit System

This is the headline feature, and it delivers. The Easyfit technology is an exclusive and patented solution that allows you to adjust the height of the back and the tension of the shoulder straps of your backpack in a single movement. In practice: put on the pack, buckle and tighten the hip belt, then pull the orange handles upward on each side. That’s it — back length and shoulder strap tension set simultaneously. The Easyfit adjustment system is described by users as a “gamechanger,” noting how easy it is to get the pack to fit comfortably. I’d agree it’s genuinely clever, particularly if you’re renting gear to guests or sharing the pack across different torso lengths. It also means you can micro-adjust on the trail mid-climb when loads shift — something traditional fixed back panels can’t do.

Load Transfer & Comfort

One tester noted being pleasantly surprised by how the Forclaz sat on hips, and with a heavy load — a full climbing rack and rope — the pack comfortably distributed the load in the proper places.

Aluminum bars in the back panel help reduce pressure and allow the back to breathe.

The hip belt carries meaningful weight for a pack at this price, and

at least one user reported trekking 150+ km with the bag to steep ascents and descents, noting it holds on to the body very well with very little to no discomfort — not feeling like “something extra on my back pulling me down.”

One honest caveat: the harness padding takes roughly three good hiking adventures to soften up — initially it is firm and rough, noticeably rough. Break it in on day hikes before you commit it to a five-day trip.

Organization

The main compartment can be accessed from the top via a drawstring, or through a large full-length vertical zipper on the front for easy access to items stored deeper without unpacking from the top. A separate zippered compartment at the bottom provides quick access to a sleeping bag or dirty clothes, separated from the main compartment.

Two elasticated side mesh pockets handle water bottles or trekking poles; small zippered hip belt pockets fit a phone or energy bars; and a dedicated internal sleeve accommodates a hydration bladder with a tube port.

The center compartment that zips down from the top made packing and unpacking gear easy and effortless

in field testing.

The hip belt pocket was the right size for snacks and can hold a phone or other small personal items for easy access.

Durability & Weather Resistance

Users report very sturdy zippers and strong material, with confidence that the bag won’t fail due to zipper malfunction while hiking.

Like most packs in this category, the fabric is water-repellent but not waterproof — designing a fully waterproof bag requires sealing every seam and using expensive zips, which is why all these bags are equipped with a protective rain cover instead.

The integrated cover stows in a pocket at the bottom and deploys quickly.

Users note the rain cover is large enough to cover most gear attached outside the pack, unlike some other brands.

Decathlon backs all Forclaz and Simond trekking backpacks with a 10-year warranty, offering repairs, replacement, or a refund in case of defects — coverage that extends to components from the zips to the seams.

That’s industry-leading at this price point.

Weight

Let’s be straight about it: 1,588g (3.5 lbs) empty is heavy by modern standards. A cottage-industry 50L frameless pack might come in under 500g. Even mid-weight mainstream options like the Osprey Talon 44 clock in closer to 1.1 kg. This pack’s weight penalty pays for the aluminum frame, robust fabric, and all the hardware. If your base weight is already north of 15 lbs and you’re not counting grams, it’s a non-issue. If you’re trying to go sub-10 lbs, the pack alone sets you back significantly.

Pros & Cons

Pros

• Patented Easyfit system genuinely simplifies fit and works well across a wide torso range (16”–21”)
• Solid load transfer for a pack in this price class, thanks to aluminum stays and a real hip belt
• Thoughtful organization: front zip access, bottom sleeping bag compartment, usable hip belt pockets
• Integrated rain cover included at no extra cost
• Very durable construction; zippers and fabric hold up to hard use
• 10-year warranty is exceptional at this price
• Around $119 — hard to beat for the feature set

Cons

• 1,588g / 3.5 lbs empty is a meaningful weight for 50L — not a pack for the gram-conscious
• Hip belt and shoulder strap padding is stiff out of the box and needs a break-in period
• External attachment points are limited; not ideal for hauling bulky gear (tent, trekking poles clip on, but daisy chains are sparse)
• Back panel ventilation is modest — expect some heat buildup on warm days
• The fabric is only water-resistant; you’re relying on the included rain cover in sustained downpours

Who Should Buy This

This pack is ideal for new or casual backpackers doing weekend to week-long trips who want a reliable, comfortable fit without a steep learning curve or a steep price. It’s also a smart pick for guided trips, group gear pools, or travelers who share gear with people of different sizes — the Easyfit system makes swapping between users genuinely fast. Budget-constrained hikers stepping up from a school daypack will find this a serious upgrade. Dedicated ultralight hikers chasing sub-10 lb base weights will likely move on quickly, but as a first real trekking pack it earns its place.

Verdict

The Trek 100 Easyfit does what budget packs almost never do: it actually solves a real problem (getting fit right) in a clever, reliable way, and backs it up with durable construction and a 10-year warranty. The weight is the honest drawback — at 3.5 lbs you’re starting a gram handicap before a single piece of gear goes in. But for ~$119, this is one of the best values in entry-level trekking packs on the market. I’d rate it 7/10: excellent for the price, just be honest with yourself about whether the weight fits your kit philosophy.
