The Sparrow 20 litres backpack is part of Wisport’s line of the latest generation of survival backpacks, is made of extremely durable Cordura Nylon and developed in collaboration with the Polish Military forces.

The main advantage of the Sparrow 20 backpack are ergonomically shaped padded shoulder straps with quick-release chest strap, two spacious independent chambers secured with durable Wisport branded zippers and multiple MOLLE attachments points.

The main compartment of the Sparrow 20 rucksack comes with a sleeve pocket on the backside and a large zipped mesh pocket on the front side. Additionally, above the sleeve pocket are: hook for attachment of hydration bag and a passage hole for hydration hose or antenna. The passage hole itself is protected against water trickling down the hose.

The back compartment has a small sleeve pocket and zipped mesh organizer and a two 20cm (8″) nylon straps, one with D-ring and one with UTX carabineer.

Quick-release Duraflex buckles allow the backpack to be quickly dropped on the ground when required.

The front and side compression straps let the backpack to be adapted to the size of the carried kit and prevent it from shifting inside the bag, which may cause unnecessary noise, discomfort and disturbance to the balance.

The front of the backpack, bottom and side panels has a multiple MOLLE strap attachments points, which allow for mounting various MOLLE accessories i.e. backpack bags, first aid kits and pouches.

Moreover multiple nylon straps permit the outside fixation of much bigger items that will not fit inside, or because they need to remain on hand. Thanks to this the overall capacity of the rucksack may be significantly greater than nominal 20 litres.

Air Comfort System (ACS):
This suspension system was designed for packs up to 30 litres and provides enhanced rigidity and easy airflow between the back of the user and the pack.

The rigidity is provided by polyethylene sheet that acts as the frame of the backpack. Increased comfort is provided by polyurethane cushions that form ventilation channels that enhance air circulation.

All elements of the suspension system that come in contact with the body are covered with AIR NET, which improves airflow.

Cons:
The shoulder straps can not be adjusted. However, this is a minor thing, since the capacity of Sparrow is only 20 liters.

The small flap covering the access to the hose for drinking system can unfasten itself when moving the daypack around.

Pros:
The support system is well padded and shaped. The pack is comfortable to wear on your back / shoulders even with heavy gear.

Zippers are dimensioned for their purpose

Ample space for 3 liters drinking system with one outlet

Lots of straps and buckles so you can adjust, optimize and configure your backpack as you want.

Sparrow 20 can be attached to other models of bigger backpacks from Wisport.

Good quality of buckles, fabric, webbing and stitching.

Mega long kompressionstraps (and straps in general). So there is plenty of opportunity to mount additional gear.

Fine with PALS webbing on backpack, making it easy to mount MOLLE compatible pouches.

A very good backpack I can easily recommend.
