Expandable 40L to 50L Capacity

This travel backpack expands from 45 litres to roughly 55 litres, offering flexible packing space for trips of three to five days. The adjustable volume lets you compress the bag for shorter journeys or open it fully when extra gear is needed. It is suited to travellers who want a single bag that adapts to different trip lengths.

17 Inch Laptop Compartment and Carry Options

A dedicated pocket fits laptops up to 18.3 inches, keeping the device separate from clothing and accessories. The bag measures 18.8 by 12.2 by 8.2 inches and includes a sleeve that slides over a suitcase handle as well as top and side grab handles for hand carrying. Hidden shoulder straps tuck away when the pack is stowed on a trolley.

Water Resistant Polyester for Extended Use

High quality water resistant polyester oxford cloth and reinforced zippers protect contents from light rain and daily abrasion. Structural reinforcements at stress points and a centre of gravity adjustment make the load feel stable during long walking days. The material is designed to withstand repeated packing cycles without premature wear.
