I AM A BONIFIED FAN OF RAIDLIGHT PRODUCTS. THIS DESIGN BOTTLE IS GREAT FOR QUICK REFILL AND DRINK ON THE GO WITH ITS SIPPING TUBES.
THE SOFT FLASK BOTTLES ARE GREAT TOO AND LIGHTER BUT MORE DIFFICULT TO REFILL ON THE GO AND REPLACE INTO THE FRONT OF YOUR PACK ALTHOUGH I FOUND THE SOFT FLASKS VERY TOUGH AND RESILIENT.
I HIGHLY RECOMMEND BOTH STYLES DEPENDING ON YOU PERSONAL NEEDS AND TASTES. THANKS RAIDLIGHT!
The hard curve pokes me in the ribs. I have to turn the bottle around so that it curves away from my body.
Love the wide mouth. Very easy to refill and stuff with ice on hot days. The hard sides also make it easier to stuff back into the front flask holders on my pack.
