Bag 55l osprey


Bag with multiple settings that make carrying very pleasant and balanced on the hips and shoulders. Delivery in 4 days in perfect packaging. I recommend this bag as well as Trekkinn.

Top class


Excellent backpack, excellent dense material, many compartments and reliable fittings. Sophisticated system for the back. This is my best backpack.



I arrive in good condition and within the agreed time. As for the super comfortable backpack, totally recommended.

The best backpack


A backpack like no other. Super comfortable and very practical. It's great because it opens in the middle giving you access to all your things in a super practical way.



This is one of the best product you can get from Osprey, serious conception, looks solid and durable, only downside will be the weight of the bag but it´s extremely comfortable.



The best backpack ever...

Awesome backpack


Suitable for long day hiking

Brutal backpack, super light! Overkill for a simple man like me hehe



Excellent backpack, however I have 174 and the S/M size was strictly. For someone taller, I recommend the L. Besides, it's just me, as I said, and I must say it's one of the most comfortable backpacks I've used

Osprey Aether 55


Fantastic rucksack. Build quality is superb and the range of adjustability is exemplary, not only for back length but with the hip belt and side straps. Plenty of options for packing kit with loads of useful features and a good size for all year round trips. Many thanks for an excellent product, highly recommended.



Beautiful bag. It fits great and it´s well built, great quality. Has tones of adjustments and the 55l is just a great all around size. Perfect!
