Lightweight team building 
The Anfibio Sigma TX is an ultralight packraft with double space, perfect for extended backpacking trips and adventure races including easy flowing rivers and lakes together with partners, children, dogs or any other big load hauling, hence 'TX' for Team Cross. 
Options are available at additional cost. When purchasing with the Anfibio raft, the options are added at a discounted price.
Two seats are included.
Configuration and outfit
The inner dimension of the boat with a length of 160cm and a width of 39cm offers enough space for two, but the outer dimensions are compact: the tube diameter tapers to 27cm at the side, the bow and stern (symmetrical) have a diameter of 50cm. The parallel hull has a width of 93cm with a total length of 260cm. In comparison to the models Alpha XC and Delta MX all dimensions have a bigger volume, thus provide increased buoyancy.
The boat uses inflatable seats with integrated backrests. The front seat has a variable position (backward or forward). However, to save weight and space one can also use baggage for seating (like dry bags, sleeping mats). 
There are 5 tie-downs for securing luggage or providing grab loops with 2 at the stern and 3 at the bow.
Material and workmanship
The Anfibio Sigma TX is made of special fabric (210/420 urethane nylon), which has a high tear and abrasion resistance despite its low weight. The smooth and shiny surface of the tube's coating is particularly scratch resistant.
All the boat’s seams are fully welded and the tube seams are additionally sewn, making it a completely glue free construction. This saves weight, costs and the environment! We grant an extended 3-year warranty on materials and workmanship.
A special feature are the reinforced lower front and rear tube segments with panels of floor fabric to ensure higher robustness when having ground contact. However, as an ultralight boat, it should still be treated with the necessary care, especially when fully loaded.
The Sigma TX is a true backpacking boat. Due to the interior space, it suits well to share it with a partner. Dog owners, hunters, fishermen and sailors will like it as a very large single boat for transporting very big loads. 
It is perfect for passages on easy rivers and lakes. For short distances and less loaded (e.g. as a single) it is capable running wild and splashy waters. 
  • Easy river travel
  • Expeditions and adventure races
  • Trekking with river sections
  • Classic packrafting tours in twosomes
  • Traveling with children or dogs
  • Trolling
  • Geocaching
  • Sailing (dinghy)
Since the model does not feature a spray skirt and has a smaller tube diameter, it is not recommended for white water, especially when paddled by two.

The boat is likewise paddled kayak or canoe style and is inflated with a big nylon inflation bag, which attaches to the boat via a screw-in valve.

No inflatable is indestructible of course, but in the (unlikely) event of sustaining damage, repairs can be done within a few minutes in the field with Patch`n Go, which bonds permanently to the urethane surface. Small pinholes can be sealed with Stormsure, a liquid urethane sealant.
