Why carry your water on your back?
Want to move your hydration to your bike without losing the convenience of a bite-valve? Use one of these super simple, but effective Adapter Caps and you can! The SWIG63 Cap makes most* 63mm widemouth bottles hydration hose friendly. The secret is a tiny silicone air-valve that relieves the vacuum pressure without leaking any water. So now you can sip from your favorite bottle hands-free.
- Measure your bottle opening, if its 63mm in diameter and has universal threads (Nalgene standard) then this adapter most likely will fit
- *Fits all 63mm (Widemouth) Nalgene, CamelBak, Polar and Hydraflask bottles
- *Does not fit 63mm Specialized, Kleen Kanteen or Zefal bottles
- Makes metal, plastic and insulated bottles compatible with any hydration tube
- Awesome accessory for almost any cycling discipline: ultra-races to bikepacking
- 100% BPA free
- Two-piece cap design makes it easy to screw on/off and clean
- Includes cap with a silicone air-valve and a "cut to fit" straw (extra valves and straws available separately)
- Our bike specific version of the SWIG Cap includes an extra straw so you can switch your Cap on to different size bottles and fittings on the Tubing to keep it tight on the bottle on the roughest trails
- Use your own Tube and Bite Valve or choose an optional Insulated Tube, Orange TruTaste Tube or Stubby Hose (3" Insulated) all topped with the ultra-reliable HydraPak Comet Bite Valve
- Works great with our Flip Clip Hose Mounts , Handlebar Hydro Mag Clips and Tether Reels (all available separately)
- Lifetime Guaranteed against manufacturing defects
- Risk-Free Purchase: if you're not satisfied, we'll send you a return label and exchange it for free!
Pro Tips:
- For mounting on a bike, it is best to bend the straw before cutting. Bend it so its end rests in the corner of the bottle and then cut it.
- You want the straw to be at the lowest point when to bottle is mounted on an angle, for example, when the bottle is mounted on the downtube. With a clear bottle, just look to make sure the straw is pointed down with its end at the lowest possible point. With an opaque bottle, line the bend of the straw up with the white air valve and then make sure both straw and valve are pointed down when bottle is mounted.
- It is possible to refill your bottle via the hydration hose with a squeeze filtration accessory, but since the air valve is a one-way valve it's best to unscrew the SWIG cap just slightly.
- Extra valves and straws are available separately, but in a pinch, you can also make your own straw by cutting some hydration tubing

Solved my problems and it'll save me so much space and time with the water bladder and faffing! The click detachment in the hose is so good, wish I knew about the SWIG before!
Purchased this item for my Polar 24oz water bottles that I use while bikepacking. I wanted a way to consume my rehydration drinks on rough roads without having to manipulate the water bottle in and out of the holder and have the ability to keep my hands on the handlebars. The cap fits my bottle perfectly and the magnet on the drink tube makes retrieving and replacing the drink tube a breeze.
So far this set up has been excellent! It fits relatively well on my 32 oz hydro flask bottle. I gave it a road test before field use and flipped the bottle upside down about 1/2 way filled with water and no spillage. You do have to make sure that the hose is secure to the lid when assembling and the bite valve takes some elbow grease to get attached initially. But overall I'm incredibly happy I don't have to clean a water bladder anymore while I can increase my hydration during hikes!!!
I bought two to use on my Cruzbike recumbent. They work great.
Works and fits great on my Nalgene and Hydropak bottles
