How is the Stem Bag different from the Shock Absorbing Cup Holder?

The Stem Bag is a larger than the cup holder and is insulated: It's meant for holding larger water bottles like a 32oz Nalgene or Hydroflask. A more traditional bikepacking style of bag, it doesn't have the shock absorbing design that the cup holder has, and isn't suitable for open drinks. 

How does the Stem Bag attach?

Three velcro straps are included, and the bag has attachement points around the top and down two sides. It is typically strapped to the handlebar and stem, with the third strap available to attach at a lower point for extra stability. 

Can it fit my 178oz bottle from XYZ bottle company? 

Maybe. The inisde dimensions are 4" diameter by 7" tall. Feel free to email us if you're unsure. 

Can I use it off the bike?

Absolutely! The optional sling strap lets you carry it for hikes, festivals, fishing, or wherever you need your bottle. 

How long can it hold ice in the real world? 

We tested it to hold ice for 7 hours in the sun on a 90 degree day. In another test we filled a Nalgene with ice and water from the home fridge, and took it to a local market on a hot day where it also lasted 7 hours. Time will vary depending on weather, amount of ice used, and other external conditions but we can say for sure it makes a big difference.

Awesome water bottle holder!

Love my new water bottle holder that will hold my large neoprene bottle and keep it cold. I especially like the fact that it is made by a family company in Colorado.

Great for hiking too!

I bought the new HandleStash stem bag and would definitely recommend. I used it for a backpacking trip and it was perfect to hold my Nalgene while hiking or hanging out at camp. Kept my water nice and cold, as advertised!

1st ride of the season with the handle stash.

Just did my 1st ride of the season with my bags and they worked great. I loaded my repair kits into them. I tend to over kill my repair kits and both bags held up just fine. I got the handle bar bag and the bottle bag. The bottle bag is versatile that I was able to put a lot of small things into it like my leather man, head lamp ect and was still able to completely close it up with out fear of anything falling out. That was put to the test when I took a digger. I was concerned that the bags would somehow get in the way either by restricting movement, my knees hitting the bags or making the bike feel awkward. I got not of that. They didn’t bounce around and make any wired noises or looked like it was they were going to fall off any second. Like I said worked great. I’m for sure going to at the very least get another bottle bag.
