Earth Pak -Waterproof Dry Bag - Roll Top Dry Sack Keeps Gear Dry for Boating, Hiking, Camping and Fishing with Waterproof Phone Case

The material looks very sturdy and it fits the essential things a family of 4 should carry for a trekking :)

Excelente mochila de 5 kg

I bought two of these bags, one large one (55L) and one slightly smaller (40L) because they looked durable and useful size for my needs. I was on the fence because I wasn't sure I needed to spend quite so much to have the extra space they afforded, but when I saw the quality, I was happy to have the product at the price I paid. This is good material, kind of soft-rubbery, not the hard, rigid rubber/plastic like some other bags. I used this bag on a mountain wilderness horseback camping trip, hoping to keep my clothes and sleeping gear dry. They both WORKED AMAZING! I put my large modular sleeping bag and pillow and large sleeping bag liner in the 55L, was able to kneel on it to get it as small as possible, rolled the top down, and the entire package stayed very flat, as if vacuum packed for the entire time. The 40L one I had jam-packed with as many clothes as I could fit. I also knelt on this one to make it as small as possible and the "vacuum pack" stayed the entire time as well. I felt that was very impressive, since the top just rolls down and buckles. (I did not expect my bags to ever be submerged on this trip, so I had no reservations about creating negative air pressure inside the bag. I'm not sure I'd do that on a canoe or kayak trip, but... they are high quality, so maybe it would work. I needed the bags to fit in or on a mule's saddle pack.) The bags seemed fairly rugged/durable. I plan to keep them out of direct sunlight as much as possible, just to prolong their usability. I didn't need the shoulder straps that allow you to wear it like a backpack. I worked the bags pretty hard and the straps are still attached, but they do seem to be the weakest point. I'd prefer it if they just had one single reinforced hand grip. All bags that are made of similar materials stink something horrible when they are opened, and these were no exception. HOWEVER, I rinsed the inside with 1 cup of white vinegar and let it sit for a while, shaking it up intermittently, and when I rinsed it out with fresh water and let it dry the smell was completely gone. Other campers with other bags had a very difficult time getting rid of the smell. All in all, I think the bag is very well made, and seals EXTREMELY well. I highly recommend this product to anyone needing a high quality large bag to keep items dry. I also think these bags will last me a long time.

I don’t think it gets any better as far as heavy duty backpacks are concerned

Güzel

Je l'ai testée à réception en l'immergeant avant de l'utiliser en conditions réelles, c'est à dire en pratiquant des sports nautiques en mer agitée. R.A.S. : je n'ai eu aucun problème à l'usage. Tout mes biens sont restés parfaitement secs ! Je n'ai même pas eu besoin d'utiliser la pochette étanche dédiée au smartphone à la seconde utilisation. Aucun problème. Il est néanmoins nécessaire de bien suivre les consignes pour le fermer correctement avant usage. Son volume (5L) et la sangle permet une certaine liberté de mouvement et de nager, surfer ou plonger aisément.
