The Viper Mission Pack is a 38 Litre pack made from 600 Denier Cordura and come with some great features.
There is the main zipped compartment with internal bladder sleeve and 2 Hydration/Coms outlets, a large front pocket, a smaller front pocket and 2 side pockets all with zip closures, I would say this Patrol pack is more like 50 Litres capacity.
It has a padded Ventex airflow back system, Padded shoulder straps and sternum with quick release buckles, adjustable hip pad harness again padded, this also has the Ventex airflow system.
You will also find multiple compression straps and all the exterior pouches have MOLLE attachments and carry handles. There is a Velcro ID pannel, 2 x V-Locks and 1 x D-Lock.
