A couple of weeks ago I ran across a relatively product, the ModCan, made by a company called TacValve. Right afterward I had the opportunity it to speak with the creator of this new 1 quart hydration flask who related that he designed it based upon his experience as a Special Forces NCO.

It seems that since the advent of MOLLE and the Camelbak hydration reservoir (and it’s clones) the GI issue 1 Qt canteen isn’t a common sight on a load carriage system. Instead, we are seeing a lot of Nalgene bottles but they are an adaptation to the function rather than purpose built for the “Soldier’s load”.

The ModCan is designed based on need. It features a large removable lid so you can quickly fill it from a stream if need be. In fact, it’s the same size as a Nalgene mouth so you can use the same screw-on purification systems you ready own. Additionally, it’s made from SERVOGARD antimicrobial and anti-fungal plastic so you don’t have the issues of the funk that would grow on the old 1 Qt GI canteen. It’s also BPA, BPS, PFAS, and phthalate-free.

Squeezable for pressurized flow, the ModCan also features a clear strip down the side called a Viewstrip, so you can see how much liquid is left inside.

Something I really like about it is that it has an NBC cap which is compatible with Protective Masks fitted with a NATO standard hydration tube by fitting an Avon Water Canteen Cap (8465-01-529-9800) or Dräger Canteen Cap. It is also compatible with a Mira Canteen Cap.
During my discussion with TacValve they revealed that they are awaiting certification from the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) for use in a slimed environment.
I’ve seen some promising alternatives to the 1qt canteen in the past but the designers were unfortunately underfunded. TacValve’s production is scalable with an ability to flex to up to 50,000 units per week. They underestimated the initial demand and are working to quickly rectify that.
We’ve currently got a military looking for US made gear that can be procured at scale during a crisis, and the ModCan fits that bill. In the meantime, they’ll be available for end of year purchases which close in early September. They can be ordered by the case which contains 72 ModCans.
Hopefully, we will see the ModCan evaluated by the Army during an upcoming Advanced Expeditionary Warfighter Experiment (or equivalent) or through the Soldier Enhancement Program soon.
Meanwhile, you can order yours at tacvalve.com. I believe they will be back in stock with week. Additionally, CANA Provisions should have them back in stock soon as well. I understand they sold out in hours last time they had them in stock.
Offered in OD Green, Coyote, Gray, Black, and Clear. I can’t wait to get my hands on some of these.


It needs a canteen cup before it can be the next canteen
I use standard Nalgene bottles and have a canteen cup that fits under them in a standard canteen pouch. Works great on camp stove for coffee or boiling water for freeze dried meals. Readily available on the commercial market.
It should work with a Nalgene style canteen cup, like the kind for Olicamp.
Lots of good cups on the market will fit what looks like close to a Nalgene footprint. My Nalgene currently rides in a USGI MOLLE canteen pouch with a Snow Peak Ti cup and lid. Its far superior to the old canteen cup.
I believe so, yes.
Interesting. Would like to try, but not sure if I can live without that unique old canteen taste!
Roger that to LCPL! It needs a Canteen Cup and a Hexamine Block stove to go with it!
