Trek TkI

Sometimes a mummy bag doesn't fit the bill - a bit too snug, a bit too constricting. For those who like the extra space and versatility of the classic tapered rectangular shaped sleeping bag, we have created the Trek series.

Incorporating our 2D PermaShell fabric and a premium 650+ Loft Utra-Dry Down, the Trek bags are a refined classic. The 60/40 fill ratio in the Trek bags is maintained using a side block baffle and differential cut shell. 

Inside the bag there is an oversized security pocket which is easily accessible, ideal for stashing passports, phones, wallets and other valuables whilst travelling. 

The Trek series is our choice for adventure travel and globe-trotting. Whether sleeping in hostels throughout Europe, backpacking in South America or discovering the Stirling Ranges in Western Australia.
