I am seeking some help with carrying a 40lb load. I am experiencing some discomfort in my traps. I have adjusted straps and rearranged the load, both with little improvement.

I'm satisfied

I used it during my Lycian Way walk in the first week of May 2023. I was satisfied. Lightness is very important, but I bought 70 liters so that everything could be inside the bag and nothing would shake from the outside.

Because of lack of compartments whenever a good amount of stuff is packed the front zip gets opened up thats why used it just once.

Used on Gr20 and Hiking in Ireland

This pack is comfortably. I found the adjusters a bit confusing as my pack veered to the side when climbing over large rocks. The hydration port is great for a bladder but the water pocket is useless. I find it hard to get the bottle out and I can not get it back in. On a hike in Ireland the belt buckle opened several times but I was able to close it again. For the money this pack is light, spacious, rugged and if you don't mind using a bladder system (mine leaked through my own fault leaving me in a bad way I wont use a bladder system again) then this bag is going great for carrying large and heavy loads. For thru hiking it is a little heavy but you'd need to pay 2.5 to 3.5 times the amount for a bag that would be say half the weight. Where the trail is technically difficult I think the stability of the weight when you lean to the side at say 90 degrees was not good as it moved to the side very fast but maybe I did not have the adjustments correct. In conclusion for less technical trails I would totally recommend this bag but if you have to go over rocks that come up to chest height and cross rivers with loose rocks in them then then the stability when the bag sways might cause you a problem though this may be down to me not setting it up right.

Good product

very nice, just what I wanted

You can buy it with peace of mind. I am someone who has changed backpacks more often than this before, but I found this very useful.

The product is very useful

I bought the product last summer. The price has increased a lot. Other than that, it is a very high quality bag, comfortable and durable. It also has an outer fabric for rainy weather.

Spacious backpack with many compartments

Used this backpack several times for hikes in Iceland. It fits a lot and has handy storage compartments. The easyfit system works easily. The handles are on the narrow side, but they do not cut into the shoulders in an annoying way. The disadvantage is that the backpack is not waterproof after a day of heavy rain; my sleeping bag in the lower compartment had become quite wet, despite the rain cover.

70 L volume. The volume of each backpack is measured using a standardised 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 litres, with a margin of error of just a few %.

Dying process

Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this environmental impact, we have opted for mass pigmentation called ”dope dye” integrating the colour pigments from the initial thread manufacture. This process reduces this backpack’s CO2 emissions by 35% compared to the previous model.

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 to hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. The water bladder can be placed in the compartment provided down the back.

Why are our rain covers grey when some trekkers want them to be brightly coloured?

The grey colour is neutral so uses less dye. We also use a “bi-ton” dyeing process where only one thread in every two is dyed. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards. Forclaz is committed to improving the environmental impact of its products through these actions.
