"I spent close to 3 hours in this store today, being fitted for and choosing a pack, and the staff are fantastic. Helpful, knowledgeable, patient and friendly - and I think I'm probably a fussy customer and I have difficulty finding packs that fit comfortably. Has to be my best experience in this kind of store to date."

"My favourite outdoor shop in Sydney. This is where you go if you want to see gear stocked because of it's quality, not just because it's corporate overload has pumped out another 10,000 puffer jackets that need to be moved before next season. Knowledgeable staff that actually partake in trekking and travelling themselves. Definitely worth dropping in!"

"Always friendly, helpful staff with great knowledge. Great range of good quality products (nothing really low end) including Australian/NZ brands e.g. Wilderness Equipment, One Planet and Aarn. Never had a fuss with exchanging unused gear within the 2 week period."
