The Anfibio Sigma TX is the lightest tandem packraft on the market so far. Weighing around 1kg per person its great for couples, ultralight enthusiasts as well as single paddlers with larger loads. An innovative feature is the reinforcement to the bow and stern segments with a panel of floor fabric.
 
Lightweight Team Cross 
 
The Anfibio Sigma TX is an ultralight tandem packraft, 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.  TX stands for Team Cross... 
 
Configuration and Outfitting
 
The inner dimension of the boat are 160cm long and 39cm wide, this offers enough internal space for two people.  The outer dimensions are compact to minimise weight: 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 comes with a inflatable seat with integrated backrests. A second seat can be puchased as an option. 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 6 tie-downs (2 at the stern, 4 at the bow) for example to secure luggage, to provide grab loops or to fasten a DeckPack.
 
Please note some of the pictures show other attachements.
 
TXV Version
 
The TXV Version has a transparent window in the floor which is great for viewing underwater wildlife as well as depth checking! 
 
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! Anfibio offer an extended 3-year warranty on materials and workmanship.
 
The lower Bow and Stern areas are reinforced with panels of floor fabric which offers increased resistance to wear. However, as an ultralight boat, it should still be treated with the necessary care, especially when fully loaded.
 
Application
 
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.

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.
 
Use
 
The boat can be paddled kayak or canoe style and is inflated with a big nylon inflation bag, which attaches to the boat via a screw-in valve.
 
Care
 
No inflatable is indestructible, 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.
