Fans of minimalist and ultralight gear will find a great selection of backpacks and market bags from Australian brand Sea to Summit. When folded, they fit in the palm of your hand, and when you open them, you get a light rucksack made of strong waterproof material with a volume of 16 to 45 liters. This type of backpacks and bags are extremely practical and comfortable for both the mountain and the city. You can always use them when you want to leave the heavy backpack in the hut or in the tent and take only the essentials with you. The material from which they are made is strong Cordura material, which is distinguished by a unique balance between weight (under 100 g) and resistance to scratches, tears and water penetration.
