Sac à dos fonctionnel,...

Sac à dos fonctionnel, grande ouverture frontale très pratique qui évite de chercher les affaires du fond du sac. Bretelles bien étudiées, de nombreux réglages de celles-ci et de la hauteur du dos en fonction de la morphologie de l'utilisateur. Dos bien ventilé lors du port , nombreuses poches. Seul petit bémol, le poids du sac, mais non rédhibitoire. Je recommande cet achat.

Pas bête les deux emplacements spéciaux pour les gourdes. Le problème, c'est qu'ils sont un léger trop derrière. Un sacré gymkana en perspective pour les remettre.

parfait

Parfait pour le tour le tour du mont blanc. Super maintient. Et bon conseil du vendeur pour savoir comment bien le régler. Très bon système de rangement. Juste la fixation prévient pour les bâtons qui n'est pas hyper pratique. J'utilise plutôt les boucles. Sinon rien à redire.

Sac relativement bien conçu...

Sac relativement bien conçu avec deux bémols selon moi : - accessibilité à la gourde sur le côté. S’il est possible de retirer la gourde d’une main il est par contre très difficile de la remettre tout seul sans l’appui d’une autre personne - les sacoches de côté placées sur la ceinture devraient être plus proche du centre de la personne pour des questions d’accessibilité aussi. Par contre bon volume bien reparti. Belle assise pour le dos. Sac très confortable pour la randonnée. Bien à vous.

Très bon équipement

Utilisé pour randonnée sur 4 jours, sacs très confortable, portes gourde bien positionnés, bien réglé il est top. Un seul bémol : les deux sangle pour fixer la tente ( en dessous) ont tendance a se desserer.

Backpack technical tests.

We conduct lab tests to validate the following components: fabric, buckles, straps, foam, zippers, etc. For example, for a fabric: resistance to abrasion, tearing, color-fastness under UV rays, washing, waterproofing, etc. A final test on the finished product simulates the kind of treatment to which it will be subjected over several years, to assess the strength of the assembly: the pack is filled with weights and placed on a dummy that replicates thousands of cycles of a fast walking motion.

10-year technical partnership warranty

The Strenfit component brand, Forclaz's partner for researching and validating its components and assemblies, conducted tests simulating backpack aging. These tests were conducted on the components, the seams and the finished product. The results of these tests are used by Forclaz and Strenfit to guarantee the bags for 10 years from the purchase date shown on the receipt.

How to pack a backpack?

Put your bedding at the bottom. Put heavier gear (tent, stove, food) closest to your back. Pack your clothes around these items. The groundsheet can be placed under the flap; the tent goes under the backpack if it doesn't fit inside. Keep your waterproof jacket and fleece to hand. In the pockets, distribute the smaller items that you use during the day (sun cream, map, sunglasses, etc.). Hydration packs should be placed in their special compartment along the back.

How is backpack volume measured?

The volume of each backpack is measured using a standardized method: we fill the main compartment, as well as each pocket, with little balls. We then empty the balls into a graduated container to get the equivalent volume in liters. The measurement is accurate to within a few percentage points. The net weight is that of our reference sample. There may be slight variations.

A score for comparing the products' environmental impact

The product's environmental impact is calculated over its entire lifecycle using different indicators. An overall rating from A to E is provided to help you easily identify the more eco-friendly products by comparing products of the same type (T-shirts, pants, backpacks, etc.) Decathlon is committed to displaying the environmental information of its products. For further information: http://sustainability.decathlon.com/

Why are our rain covers colored gray? when some backpackers would prefer red or orange

The gray color is neutral and therefore uses less dye. The component is made of BITON: as a result, the environmental impact of the MT900 70 L is 7.3% less than the former model: symbium access. By using dope-dye for the lining materials, much less water is consumed than a more brightly colored fabric. It is by taking small measures of this kind that Forclaz is demonstrating its commitment to improve the environmental impact of its products.

Symbium technology

In order to be comfortable, a backpack must also be balanced as you walk along. The symbium technology is an articulation of the waistband that allows the backpack to conform to the backpacker's movements when walking. Thanks to the Symbium system, there are no more pendulum effects, which will ultimately tire out the backpacker after a while.

Imported

Product testing

All our backpacks are tested in the field by users who represent the target market under the same conditions as you would encounter in use. In particular, our "Mission Tests" bring together the product manager with people who are not affiliated with QUECHUA to test, improve and validate our products. This specific model was approved by hikers touring the Mont Blanc in June 2017.
