[Manager's comment]
The British brand CRUX is known for its "fully waterproof" and "high durability" features! Just hearing these words gives you a sense of security. However, these two features might make you worry about the weight, but it's actually very lightweight. It doesn't have any convenient external pockets, but that's exactly why it can be freely customized and attached. This is the perfect backpack for activities where you carry a lot of luggage and get wet, such as canyoning, backcountry skiing, and packrafting!
The RK40 has a roll-top design and a capacity of 40L, but the actual capacity is about 45L. It is recommended for summer camping, hiking, and mountain stream fishing.
According to the person in charge at the import agency, there has never been a repair that they couldn't do before, so the fact that you can keep using it for a long time is highly appreciated.

A lightweight, fully waterproof alpine backpack that has continued to evolve since CRUX was founded.
It is completely waterproof and can withstand snow, rain, and other weather conditions, and can also be used for hard activities such as climbing, river climbing, mountaineering, ice fishing, sailing, and kayaking.
RK Series [Roll Top Type]
The roll-top design without a top lid allows for quick access to the main compartment, and the large opening makes it easy to see inside and take out what you need. Another big attraction is the lightweight design due to its simple structure.
[Two senses of security]
Welding is used to ensure complete waterproofing.
The seams of the fabric are pressed together rather than sewn to prevent water from seeping in. Furthermore, the lining is coated with a water-resistant coating of 10,000 mm, achieving waterproofness on a par with that of rain gear.
Being completely waterproof means you can feel safe in the rain while hiking, climbing streams, or alpine climbing. The roll-top is made of flexible material, making it airtight and completely waterproof. It also helps reduce the weight of your gear by eliminating the need for a separate dry bag.
Its high durability comes from the use of Kevlar, the same material used in bulletproof vests. This durable material means it is less likely to break on rocky areas, walls, streams, and ice routes, giving you peace of mind.
It provides more targeted utility to meet users' hybrid needs.
The side compression straps have been replaced with reflective bungee cords for additional fastening, the side mesh pockets are now zippered to store wet clothes and small gear in a ventilated space, and a full-length zippered compartment on the front panel provides a separate place to store a shell jacket or raincoat when the weather gets unpredictable.
【Features】
The buckles (female) in frequently used areas are made of aluminum to reduce the risk of breakage (top lid, waist belt).
