  • Familiarity: I've put it through the wringer

I have had this pack for just over a year and it has done magnificently well. I have done over 200km in the field with this baby lugging from a very comfortable 26kg to a miserable 38kg. Under the 38kg load it performed well through three days of solid rain topped off with two days of snow, nothing on this pack failed to work. The external bladder compartment is worth its weight in gold, when you’re buggered and need to refill your water there is nothing worse than having to dig into a back to remove a bladder.
This pack is good for two to three night trips also, a bit much for just an overnighter though and totally excels when it comes to the long hauls through varied weather conditions coz you can pack just about everything in your wardrobe and still have room left over.

Hi. What is the frame height of the Xenith 105 Large please?

Responded on

Hey Sean,

I measured the frame and the size large for the Osprey Packs Xenith 105 is 28.5 inches from top to bottom. I hope this helps.

This video provides a glimpse into product conception, prototyping, testing, production, inspection and shipping.

If my height is 190 cm / 6'2 what size is...

If my height is 190 cm / 6'2 what size is best to take - L or XL?

Responded on

Hey Alexey,

Packs are measured by torso length which is from the C7 vertebra (that bump where your shoulders and neck meet) and your hip-shelf (the very top of your hipbone). Torso sizing is as follows: M (18 -21 inches) L (20-23 inches) XL (22-25 inches)

Nice pack

  • Familiarity: I've used it once or twice and have initial impressions

A great pack! Plenty of room for my things including my Ham radio gear and dog stuff.Not sure how well the buckles will hold up and would like longer straps for my pads on the bottom.Make sure you spend extra time fitting the pack and you will be pleased with it.

Initial Impressions

Great pack for long backpacking journeys, plenty of room to fit my rather bulky sleeping bag, tent, sleeping pad, pillow and other essential items. There is exceptional extra room for food and water after all of the essentials are packed i'm very excited to use this pack. The support it provides to your back is remarkable
