1. Capacity and compartmentalization

Capacity

The capacity of your canyoning bag is a decisive criterion, depending on the duration and nature of your outings. For day trips, a capacity of 30 to 40 liters is generally sufficient. For multi-day expeditions, a 50-liter or larger bag is more appropriate. It's important to choose a bag that offers enough space to carry all the necessary equipment, including ropes, carabiners, descenders, a change of clothes, food and water.

Compartmentalization

A good canyoneering bag should offer smart compartmentalization for easy access to your gear. Look for models with specific pockets for small items, compartments for wet and dry clothes, and external pockets for frequently used items. A dedicated compartment for the hydration system is also a plus, allowing you to stay hydrated without having to remove the bag.

2. Materials & Construction

Materials

Durability is an essential criterion for a canyoning bag. Materials must be abrasion-, tear- and weather-resistant. Canyoning bags are generally made from PVC, coated nylon or TPU (thermoplastic polyurethane). These materials offer excellent resistance to water and wear, guaranteeing a long service life.

Construction

Bag construction must be robust and reliable. Seams must be reinforced and watertight to prevent water infiltration. Zippers and buckles must be corrosion-resistant and easy to handle, even with gloves or wet hands. Bags with additional reinforcements on the areas most exposed to wear, such as the bottom and sides, offer greater durability.

3. Comfort and Ergonomics

Carrying system

Comfort is paramount on long climbs and technical descents. The carrying system must be well designed to distribute weight evenly over shoulders and hips. Look for packs with adjustable, padded shoulder straps and an ergonomic waist belt. Some models also offer a ventilated back panel to reduce perspiration and improve comfort.

Adjustability

Adjustability is another crucial aspect. A canyoning bag must be able to adapt to different body shapes. Shoulder and hip straps should be easily adjustable to guarantee optimum support. Some models also feature adjustable chest straps to stabilize the bag during descents.

Weight

Bag weight is an important factor, especially on long ascents. Opt for a lightweight but sturdy model, made from resistant materials such as nylon or PVC. Ultralight bags are ideal for fast outings, but make sure they offer enough functionality and comfort for your needs.

4. Specific features

Drainage system

A good canyoning bag should be equipped with an efficient drainage system to quickly evacuate any water that enters the bag. Look for models with drainage holes strategically placed on the bottom and sides of the bag. Some bags are also equipped with drainage nets or grids to improve water evacuation.

Hydration system

Dehydration can quickly become a problem on long climbs and technical descents. A canyoning bag should be compatible with a hydration system, such as a water pouch or water bottle. Look for models with a dedicated compartment for the water pouch and outlets for the hydration hose. Some bags also offer side pockets for water bottles.

Accessories and options

Canyoning bags can be fitted with various options and accessories to enhance their functionality. Among the most useful are compression straps to stabilize the load, attachments for ropes and carabiners, pockets for small items, and rain covers. Some top-of-the-range models also offer fastening systems for helmets and shoes.

5. Durability and care

Weather resistance

Canyoning weather conditions can be unpredictable. A canyoning bag needs to offer some resistance to the elements. Look for models with water-repellent treatments or waterproof coatings. An integrated rain cover is also an asset for protecting your equipment in the event of heavy precipitation.

Maintenance

Good maintenance extends the life of your canyoning bag. After each outing, rinse the bag in fresh water to remove salt and sand residues. Leave to dry in the open air, out of direct sunlight. Check seams, zips and buckles regularly to ensure they are in good working order. Store the bag in a dry place away from direct sunlight to prevent material degradation.

Choosing a canyoning bag is a crucial decision for advanced practitioners. By taking into account capacity, compartmentalization, materials and construction, comfort and ergonomics, specific features and durability, you can find the ideal bag for your canyoning adventures. Don't forget to check compatibility with your other equipment and to test the bag in conditions similar to those you'll encounter on your outings. With the right bag, you'll be able to enjoy every descent and ascent to the full, safely and with optimum performance.
