The FITLY FLASK1100 (BLADDER) is a 37 oz (1100 ml / 1.1 L) low-profile hydration bladder custom-shaped to fit the FITLY Sub180 adventure pack. Includes a drinking tube with silicone mouthpiece plus a screw-on mouthpiece for standalone flask use. Fits only the Sub180 -- too large for Sub90 or Sub45. Same shrink-as-you-drink TPU design as the smaller FITLY flasks, in a flatter 12 x 6.5 inch profile built to lie flat against your back on longer outings.
Noteworthy FLASK1100 (BLADDER) features include:
• 37 oz (1100 ml / 1.1 L) capacity in a low-profile 12 x 6.5 in shape
• Drinking tube and silicone mouthpiece included
• Screw-on mouthpiece for standalone use (included)
• Custom-fits the Sub180 (not Sub90 or Sub45)
• TPU construction, 100% BPA and PVC free
• Freezer safe -- doubles as an ice pack on hot days
• Top-rack dishwasher safe
• Max temperature 122F
• Two colors: Blue and Black
What's the capacity of the FITLY FLASK1100 (BLADDER)?
The FLASK1100 (BLADDER) holds 37 oz (1100 ml / 1.1 L) in a low-profile 12 x 6.5 inch shape custom-made to fit the FITLY Sub180 adventure pack.
Which FITLY pack does this bladder fit?
The FLASK1100 (BLADDER) fits only the Sub180. It is too large for the Sub90 or Sub45. For the Sub90, see the FLASK500 (BLADDER) instead.
Can I use the FLASK1100 as a standalone flask?
Yes. A screw-on mouthpiece is included so you can use the bladder as an oversized standalone soft flask when you don't want to use the drinking tube.
Is the FLASK1100 (BLADDER) dishwasher and freezer safe?
Yes to both. The TPU bladder is top-rack dishwasher safe and freezer safe. Max operating temperature is 122F.
How does the shrink-as-you-drink design help on long runs?
As the bladder empties, the flexible TPU walls collapse onto themselves and push liquid out without needing air inside. On long outings, that keeps a shifting water load from sloshing or thumping against your back as you move.
