Updated Summer 2025

I’ve owned Anfibio Sigma TXLs for over three years and am now on my second, a blue TXL+. I’ve done several day trips two-up, solo and some sailing. It’s all helped give me ideas on how to refine this boat to my needs.
On buying the first green one I got the optional Multimat airfloor, additional foam block seat, paddle leash and use my old Anfibio DeckPack on most trips. I also got a spare skeg patch and mounted a second skeg under the bow – it made things worse. Here’s a reappraisal of the Sigma TXL+ followed by a list of mods which have worked for me.

Spacious solo
Light for its size
Room for 1.9 people
TubeBags very handy, even for day trips
Level solo trim (unlike Rebel 2K and similar)
Multimat floor’s benefits are noticeable (OK to sleep on, too)
Broad, thick front seatbase jams in and spreads the load: less floor sag when solo
Thicker 420-D floor extension ‘bumpers’ over bow and stern
Variety of set-ups and sitting positions, solo or two-up.

Stock skeg mounted too high (or too small)
Inflatable front backrest lacks support
Optional foam seat block unusable
For me, the paddle leash was inferior to my regular mooring line
An Exped-style dump valve in the seatbase would be nice (instant deflation)
Reduced floor space when two-up with Multimat (depends on your sizes)

Best Sigma TXL Modifications & Tips

Knee straps improve boat connection both on flatwater and when waves get lively, plus they help bracing into a headwind and are handy lifting handles on land. Above is the old Anfibio version which requires gluing on 4 tabs as none of the stock ones line up or are robust enough. Anfibio do a ‘5-P’ thigh strap – even more gluing needed but better for whitewater.
Newer TXLs come with ‘ladder’ fitting tabs on the hull sides
