Thunder Competition Gen III Tunnel Bags

Price: Starting at $80 per set
Item Number: A1103GII
Manufacturer: Salty Dog Canvas
“We’ve been producing and competing in agility trials for 23 years and these are simply the best tunnel holders we’ve ever used.” Agility Ability, Sparks, NV
This innovative, low profile design "cradles" the bottom edge of the tunnel so it stays in place and the bags do not creep beyond the tunnel ends, even on rubber matting or artificial turf. The extra-wide, one-piece strap spans more than 2 wire ribs on a 6" pitch tunnel so the tunnel doesn't collapse and there's no chance of overtightening. A heavy-duty foam padded handle (see photo) on each bag makes them easy to lift and carry together. Fits 24" diameter; 26" is special order. Available with blue bags, yellow ends and yellow straps. Custom colors available.

Note: for artificial turf and soft sand we recommend our McWedge Pro Turf tunnel bags.

Sold as a set: two empty blue bags and connected with a yellow strap. One set holds one tunnel end. (Same as photo.) Tunnels 15' (4.5m) and longer typically require another set in the middle.

  • Strong and durable: UV-resistant, 18oz coated vinyl (PVC) sewn with SunGuard double-bonded UV-resistant thread.
  • Tunnel Support: The ultra-wide strap spans more than 3 of the wires ribs on a 4" pitch tunnel; 2 wire ribs on a 6" pitch tunnel.
  • Wide Footprint: Bottom that makes contact with surface measures 17" x 7".
  • Heavy-duty top opening: Delrin zipper does not support rot or mildew, is UV coated and self lubricating so it operates smoothly despite sand, mud or other grit.
  • Easy to move and reset: Grab the handles, pick up the bags (bend your knees!), hold them so the strap is over the tunnel end and lower the bags — the weight of the bags automatically secure the tunnel in the correct position - here's a quick video.
  •  Easy Fill: Unzip the bag and fill with sand or pea gravel to the desired weight. 
  • Optional Two-Piece Strap: The same wide width as our one-piece strap and is Velcro fastened. Straps are color coordinated so all same side Velcro are sewn onto one yellow strap making it easier for ring crew to locate a matching pair. Matching side is a blue strap. A grab handle on one strap makes it easier to lift and fasten especially when placed in the center of the tunnel.
  • Optional water bladder inserts: 20 litre (5.28 gallon) food-grade bladders with screw-off cap. Two bladders per set ordered. Just unzip, unscrew the cap and fill the bladder with water to the desired weight. First time users, please watch our filling instruction video. Bag weighs 28lb (13.6 kg) full of water or as heavy as one can carry when filled with sand or pea gravel.

VOLUME DISCOUNT: if purchasing 10 or more pairs, please Contact Us for club pricing

"Your Thunder bags are awesome. They hug the tunnel so well that we didn't have to adjust the tunnel ends the entire two-day trial."
Sharon Dunsmore, K9 Klubhouse

Great product

We purchased our first tunnel bags from Salty dog in 2014 . We have 100 plus dogs in classes each week and put on trials and demos . They show no wear and tear and hold the tunnels in place very well . We are buying some more.
Love 'em!

These bags work much better on my mats than the typical tunnel bags.
10 out of 10

At our trial we had 650 dogs passing though the tunnels, both big and little dogs, and no movement of bags and we run on mats. These bags get a 10 out of 10 from us.
Bags are AWESOME

Used bags at our trial on the weekend. Love, love, love! So easy to move around and held the tunnels great.
Best Tunnel Bag Yet!

My Border Collie, Crosby, comes from champion flyball lines, and when he hits a tunnel at full speed, it moves a lot. He is often knocking the old style bags over, which can obviously be dangerous. Well, after several training sessions with our new Black Thunder tunnel bags, the tunnel has not moved and no bags have been displaced! I am more than thrilled with this product!

"Fits perfectly and makes icing sore joints and muscles easy. I just put on the coat, put poodle in stroller and set timer so remember to take off coat."
