Edit - Geigerrig Hydration Engine - Art Tosborvorn

Art, Welcome to BackpackGearTest.org, and thanks for your Owner Review. I’ll be your editor. This is a good start at a first OR, and I look forward to working with you to get it ready for posting.
  
 My edits below are in standard BGT format:
  
 EDIT (all caps) – required change
 Edit (initial cap) – suggested change or request for clarification
 Comment – just that, no change required
  
 After revising you need to do two things. Post the html version of the Report in the Tests/Owner Reviews folder on BackpackGearTest.org, and post the plain text version here, with "Repost," the product name, and your name in the subject line, and with a tinyurl link to the html version in the body of your message.
  
 Cheers, Richard Lyon

 Owner Review by Art Tosborvorn
 June 5, 2015
 Edit: Both for consistency with other Owner Reviews and because it looks better, consider centering the title.
  
 ###Weight:    145 lbs###
 EDIT: 145 lb [BGT abbreviations are always singular.]
 EDIT: Add the metric equivalent. 
  
 ### I started hiking/backpacking a few years back, mostly in Yosemite and other California parks. I haven't done much overnight camping, but hope to do more this year. I also like taking photos on my trips. ###
 EDIT: Two things – Give this section a title (such as Backpacking Background); and add a bit about your hiking style – pack weight, typical shelter, favorite venues, etc. Be mindful of our 100-word limit.
  
 ### Website: www.geigerrig.com http://www.geigerrig.com ###
 EDIT: Make this link clickable to the manufacturer's website.
  
 ### Size reviewed: 3 L (100 fl oz). The 2 L model (70 fl oz) is also available. ###
 Edit/Comment: This is OK, but be aware that hydration volume is one of the few items as to which no conversion is required if you use liters.
  
 ### To insert a tube, I simply push the tube into the receptacle. To remove a tube, I press the button which would unlock the locking mechanism###
 EDIT: which unlocks
  
 ### Start from an empty bladder, I begin by opening up the bladder ###
 EDIT: Starting from
  
 ### One thing that helps is if the hydration sleeve is hard. ###
 EDIT/Edit: Not sure I understand what you are saying here. Please explain.
  
 ### I also found it helpful in cleaning cuts, spot-cleaning my gears, etc.###
 Comments: Geigerrigs are great for first aid!
  
 ### Bob Geiger, the CEO's. ###
 EDIT: the CEO
  
 ### 15 miles (24 km) day trip to Half Dome. Sunny, clear sky. Temperature somewhere in the 70 F - 80 F (20 C - 30 C). 
 EDIT: For each of your destinations you need to give a more complete location. [Believe it or not, not everyone knows where Half Dome is.] So Half Dome in Yosemite National Park; Lake Tahoe, California; Torres del Paine, Chile; Mt. Whitney, California.
 EDIT: 70F-80F (21-26 C)
  
 
 ### This means that it could go into a 60L backpacking pack no problem. With smaller packs, though, it seems like the tubes have to be rolled around inside the hydration sleeve a little bit, and that could be a challenge. ###
