Product care
Load heavy items close to your back and high, and use the compression straps on a part-filled pack. Set the hip belt on your hip bones first, then the shoulder straps, then the sternum strap. Dry it fully before storing, especially the hydration sleeve, which is where mould starts. Sponge clean rather than machine washing. Check the hip belt and shoulder strap stitching before any big trip.
Full details

A 90 litre hiking backpack built for the trips where a weekend daypack simply runs out of room. The main compartment swallows a sleeping bag, tent, stove and several days of clothing, while an expansion section adds extra volume when you are carrying bulky winter kit or hauling gear for two. Water resistant polyester shrugs off drizzle and trail spray, and the reinforced base takes the abuse of being set down on wet rock and gravel.

Load carrying is handled by wide padded shoulder straps, a supportive hip belt and an adjustable sternum strap, so weight sits on your hips rather than dragging on your shoulders over long distances. A built in hydration sleeve routes a bladder hose to the chest, side compression straps stop a part filled pack from swaying, and external lash points carry a roll mat, trekking poles or an ice axe. Multiple zipped pockets keep a map, headtorch and first aid kit within reach.

Suited to backpacking, mountaineering, wild camping, Duke of Edinburgh expeditions and long haul travel where a hold bag is impractical. Available in military green, black and dark blue, each with the same hard wearing fittings and smooth running zips. Fellmont Outdoors chooses gear that earns its place on the trail, and this rucksack is the one to reach for when the route is long and the kit list refuses to get shorter.

  • Capacity: 90 litres with expandable section
  • Material: water resistant polyester
  • Hydration bladder sleeve with hose routing
  • Padded shoulder straps, hip belt and sternum strap
  • Side compression straps and external lash points
  • Colours: military green, black, dark blue
  • 90L Plus an expansion section
  • Hydration Bladder sleeve and hose routing
  • 3 colours Green, black, navy

Capacity

For the kit list that refuses to shrink.

Some trips simply need volume: **winter kit, gear for two, or an expedition where resupply is days away**. The main compartment takes a **sleeping bag, tent, stove and several days of clothing**, and the **expansion section** adds more when you are carrying bulky cold-weather gear.

  • **90 litres** with an expandable section
  • **Sleeping bag, tent, stove and days of clothing**
  • **Backpacking, mountaineering, wild camping, expeditions**

Carrying the load

Hips take it, shoulders steady it.

At this volume, how the pack carries matters more than anything else on the page. **Wide padded shoulder straps, a supportive hip belt and an adjustable sternum strap** put the weight on your hips where your legs are, and the **side compression straps** stop a part-filled pack swaying into you on a traverse.

  • **Hip belt** carries the weight, not your shoulders
  • **Adjustable sternum strap** to stop strap spread
  • **Side compression** for a part-filled load

Access and attachment

Water on the hose, kit on the outside.

A **built-in hydration sleeve routes a bladder hose to your chest**, so you drink without stopping — on a long day that genuinely changes how much water you take in. **External lash points** carry a **roll mat, trekking poles or an ice axe**, and **zipped pockets** keep a map, head torch and first aid kit reachable.

  • **Hydration sleeve** with hose routing
  • **Lash points** for mat, poles or axe
  • **Zipped pockets** for map, torch and first aid

  • Luther Hickle18 April 2026

    Strong seams, strong strips, unbelievable. Such a bag at its price is really satisfying. I wanted to go out with it for 3 days in the forest and enjoy the product.

  • Keven Feeney18 April 2026

    Good item. It looks very durable and with its waterproof feature, even if it rains, it will be perfect for vacationing. My son really liked it. It arrived very quickly. Thank you.

  • Jonathon Gleason16 April 2026

Frequently Asked Questions

Is 90 litres too big?
For most trips, honestly, yes - and that is worth saying. 90L is an expedition and winter volume. The risk with a very large pack is that you fill it because the space is there and end up carrying weight you did not need. If your usual trips are long weekends, a 60L pack will serve you better.
How much weight can it carry?
No maximum load is published, and volume is not a load rating. The harness is built to move weight onto your hips, but what you can carry is limited by your legs and back rather than by the bag. Pack it, weigh it, and be honest about whether you want that on a hill for eight hours.
Will it fit me?
No back length or adjustment range is published, which matters more on a 90L pack than on anything else here. Load it with weight at home and walk around - the hip belt should sit on your hip bones with the shoulder straps wrapping without a gap at the top. If it does not fit, return it rather than enduring it.
Does it come with a rain cover?
No. The polyester is water resistant and the base is reinforced, but there is no cover included and the seams are not taped. For British hill weather, buy a cover to fit 90L and line the inside with dry bags - that is what experienced walkers do regardless of the pack.
Is a hydration bladder included?
No - the sleeve and hose routing are built in, but the bladder is bought separately. Most standard 2 or 3 litre bladders will fit.
Can I take it as hold luggage?
It is far too big for hand luggage and large even for hold baggage on some airlines, so check your allowance. Whatever you fly with, tuck the straps away or use a transit cover - loose webbing on a 90L pack is exactly what gets torn off in a handling system.
