To each their own style! There are many ways to protect your belongings while trekking, each with its advantages and disadvantages.Poncho cape:In terms of external protection for the bag, the poncho is undoubtedly the most effective solution as it allows the user and the bag to be completely covered, without the risk of leaking at the back. The main problem is the lack of mobility and convenience when it comes to putting your bag down or accessing it.Rain cover:Lightweight and quick to install, the rain cover is an exterior protection. It fits over your backpack in seconds if its case is accessible from the outside (which is the case with our latest bags like the MT500 AIR). In a group, everyone can help their neighbour to put it on without anyone having to put their bag down.When coloured, they are a practical visibility feature in fog or at night.The disadvantage of rain covers is that they do not protect the shoulders. In the event of heavy rain, it is not uncommon for water to seep through the back of the bag and it is therefore necessary to protect your most sensitive items in small waterproof bags.On the other hand, rain covers are susceptible to holes and tears.Reinforced rain cover:Like the classic version, this cover protects against rain and has two sides: a classic visible side (orange) and a reinforced dark side to better resist cuts and holes that can be caused by branches. However, they are heavier.Water-repellent storage cases:Available in a variety of sizes, the waterproof storage covers allow you to better store your belongings in your bag and protect them from moisture. The only problem is remembering what you put in it or you might have to look for your belongings. Beware: these cases are not completely waterproof. They are therefore not suitable for long exposure to water (do not use outside the bag).Waterproof storage cases:More resistant and above all 100% waterproof, these covers are ideal for protecting very sensitive equipment or for protecting items outside the bag. Unfortunately, their plastic structure makes them stiffer and heavier.
