Grand Canyon Hancock 5.0 XW Isomatte Long OD Green

Anyone who spends a lot of time in the great outdoors knows how crucial a good night’s sleep is to your performance. The Grand Canyon Hancock 5.0 XW Isomatte Long OD Green has been developed for users who do not want to compromise on comfort, insulation and space. This extra-wide and long self-inflating sleeping mat ensures you are not lying directly on the cold ground, whilst providing optimal support for your body, even during longer military simulation events or multi-day outdoor trips.

Usage scenarios

This sleeping mat really comes into its own in situations where comfort and reliability are essential. Think of milsim weekends where you spend several nights in the field, bushcraft sessions where you want to travel light but efficiently, or outdoor overnight stays where temperature fluctuations are a factor.
In practice, we’ve noticed that taller players or users with broader shoulders often find standard narrow sleeping mats too small. Measuring 198 × 76 cm, this mat offers plenty of space to move freely without rolling off the edge.
This mat also works excellently as a comfortable surface during rest periods throughout the day, for example between skirmishes or whilst on observation.

Materials and techniques

The Hancock 5.0 XW uses a self-inflating system with high-quality foam that automatically fills with air as soon as you open the valves. Thanks to the two large screw valves, this process is quick and efficient, with the option to add extra air for a firmer feel.
The 5 cm thick foam offers an R-value of approximately 4.5, meaning you are well insulated against cold surfaces, even in lower temperatures. The horizontally perforated foam structure reduces weight without compromising on support.
The top surface is lightly textured for extra comfort, whilst the non-slip underside ensures the mat remains stable, even on uneven or slightly sloping surfaces.

Practical experience

In practice, we’ve found that users really notice the difference after spending several nights outdoors. Whereas thin mats often lead to pressure points and fatigue, this mat distributes body weight more effectively. Side sleepers in particular will find that the extra thickness and width really make a difference.
Many users encounter the problem of ‘sinking through’ their mat in cold weather, allowing the cold to seep through. With this mat, that insulating layer remains intact.
On colder nights during milsim or bushcraft scenarios, the combination of foam and air ensures you can sleep comfortably without having to carry extra heavy equipment.

Who it is / isn't suitable for

This sleeping mat is ideal for players and outdoor enthusiasts who value comfort, insulation and extra space. Think of milsim players, bushcrafters, professionals and campers who spend extended periods outdoors.
For ultralight hikers or minimalist setups, the weight of approximately 2.5 kg may be a consideration. If you prioritise maximum compactness over comfort, lighter alternatives may be more suitable.
