It weighs just 2kg and you no longer have to pack poles on your next hike. Whats even better the modularity of the Onelink means that you only put up what you need when you need it.
Raining? Put up the fly first, cook under it, then string up the hammock to relax off the wet ground. Or if it's a warm dry evening just chill out on your hammock until the bugs come out then string up the bugnet and settle (literally) under stars for the rest of the evening.
