Over the past years, several improvements have taken place with regards to lifespan enhancement of the four main tent fabrics. Examples:
- Some years ago, 0.51 oz/yd² DCF was claimed to withstand only ~150 nights due to pinholes and delamination. In the meanwhile, users report way longer lifespans with newer DCF generations
- Sil-Poly has widely replaced Sil-Nylon thanks to reduced fabrics sag
- UltraTNT has entered the market
- Sil/PU, although cheaper, is rarely used anymore due to inavoidable delamination of the PU layer
I would be interested to know if a "tough" DCF version like DCF8/CT2E.08 (0.78 oz/yd²) might provide the same longetivity as the "gold standard" of tent fabrics, say Sil/Sil-Nylon 6.6 in 30D thickness?
What are your up-to-date experiences about longetivity of DCF or UltraTNT?
