Third time lucky

Ok so this is definitely the bag! Having tried out 2 other bags before this got this watched the video and was blown away.. Tested on a 9mile hike and a bit of scrambling in the Peak district and was impressed, however used it recently to climb Scafell Pike via Broad Crag, Esk Pike, Bowfell, Crinkle Crags, 15kg and 2 nights of wild camping. The most impressive bit was during an all day downpour.. the waterproof cover covered the whole bag - to give in context: i had a sleeping bag in-between the lid and the opening at the top, a tent at the bottom that was horizontal, cooking gear, stove, gas etc and a sleeping mat which although wasn’t covered, wasn’t a problem! I really hope the bag does last but so far it has been through 3 rough days and it did well

Lightweight overnight backpack

I've had this pack for a few months now, used it for day hikes in the Lake District and wild camping in the Peak District, have to say I'm very impressed. It's light, and has some very clever features, strapping is good and it's very comfortable. All in all I would definitely recommend it.

Value for Money

Ive used this pack for 3 months now & feel that it has earned a review. I bought this pack on a spur of the moment purchase & have to say I have not been disappointed with it at all, I unbuttoned the lid as I didn't need it & use the pack for multi day hikes which I have now completed a few in this time. Its comfortable, fits my gear no probs and everything is at hand. Its a well thought out pack & for the price I paid puts a lot of dearer equivalents to shame. Time will tell if its durable or not but at the moment I have no worries over anything as its well constructed and fits my needs perfectly.

Toller Mehrtages-Rucksack

Ich habe mir diesen Rucksack für meine letzte Mehrtageatour in den Bergen gekauft und kann sagen, dass ich rundum zufrieden bin. Durch die vielen Einstellungsmöglichkeiten passt und sitzt er richtig gut. Der Aufbau und die ganzen Fächer sind echt durchdacht und erleichtern z.B. den Zugriff auf das Hauptfach. Ich würde ihn sofort wieder kaufen.

Seitentaschen sind zu eng , alles ist schmal gehalten , der Rucksack wird jetzt in einer Woche richtig getestet bin mal gespannt wie er sich bewert , ist alles nicht so robust

La compramos sin tenerlo muy claro y ha sido todo un descubrimiento. El tamaño, la comodidad y la cantidad de compartimentos son ideales. Totalmente recomendable.

The bag has a 50 L (3051.2 in³) capacity with an extra 10 L (610.2 in³) extension capability. The volume of each backpack is measured using a standardized method. we use small balls to fill the main compartment as well as each pocket. The balls are then emptied into a graduated container in order to determine the equivalent volume in liters, with a margin of error of just a few %.


3.7 lbs all-inclusive. Weight of the removable rain cover 3.5 oz

Air design

As with the MT900 UL line, the MT500 Air range has a ventilated back structure with mesh fabric (net fabric) that helps the back to breathe and dries quickly. Rigidity is guaranteed by a reinforced frame. The back is adjustable with a release strap that’s easy and quick to use.


Polyamide main fabric 210D RS (Ripstop = increased resistance to tears), reinforced bag base (420Dx330D RS)

Recommended carry weight

According to the project for which this backpack was designed, we recommend you don’t load it above 33 lbs. Then you can benefit from all its features. Moreover, it’s not recommended to carry a load greater than 20-25% of your own weight and put too much pressure on your back.

How to pack a backpack

Put your bedding at the bottom. Put heavy gear (tent, camp stove, food) near your back. Store your clothing around it. A groundsheet or tent can be placed under the flap or under the bag if there isn't room inside. Keep your waterproof jacket and fleece at hand. Place small items for daily use (sunblock, map, glasses, etc.) in the pockets. The water bladder can be placed in the compartment provided down the back.

How to use the multiuse straps

The new range of MT500 Air and MT900 UL bags has 2 straps with open aluminum buckles (on the lower part of the bag). These straps let you hook on a tent or mattress under the bag or on the barrel. If not in use, these straps can be stored (by pushing them inside) in the hidden pocket intended for this or detached and used elsewhere with the lark's head knot buckle.
