The backpack is durable and carefully sewn, the seams are solid, and the molle straps and front cutouts are made of good quality materials. So far, the zippers work flawlessly. However, I am wondering about the stated capacity of 51 liters because the backpack actually holds around 38-40 liters. Still, I managed to fit in: a large 2L bottle, three smaller 0.33L bottles, a 0.5L isotonic drink, a hammock, two sitting pads, a large folding Japanese saw, an Arpol emergency food ration, an extra food portion, a large raincoat, a set of underwear and a combat sweatshirt, a hygiene kit, insect repellent, thick tactical gloves, a map holder, 5 meters of 4mm rope, a metal cup, and a roll of toilet paper. I attached small EDC items to the molle on the sides of the backpack. A very practical solution was used for the ends of the compression straps – after shortening, you can fasten them with Velcro so they don't get tangled. However, I have three minor remarks: first – at a height of 180 cm, the chest strap settled on my neck when fastened and was difficult to adjust due to stitching on the straps. Second – the hip belt stabilizes the backpack well, but it could be wider. Third – the straps at the bottom are a bit too short for a larger mat. Despite these small issues, I think it's a functional, comfortable, and well-made backpack worth buying.
