My wife (Lori) and I both endorse Fjallraven shorts AND trousers for cycle touring. In preparation for a 2,500 mile trip in South America in 2023, we took a chance and purchased Specialized / Fjallraven (S / F) shorts
and trousers. Specialized and Fjallraven formed a partnership and, at that time, they were 50% discounted at Specialized' website. I don't think you can purchase the S/F models anymore as the partnership ended and most of the inventory sold. But the model to look at is the Hoja Hybrid line. We both have used their shorts and trousers over long distance trips. In fact we are on one as I speak (with the Fjallraven clothing).
Pros: DURABLE! 1000's of miles and the stitching is still intact. The color fades, but oh well. Gusseted crotches for cycling comfort with stretchy material. Tapered legs (on rhe trousers) so the material on the right doesn't get caught in the chainrings. Zippered pockets for excellent security (4 pockets on trousers). The G-1000 fabric is sonewhat water resistant but can be made mire water repellent by using Fjallraven's wax. The trouser cuffs can be folded up revealing retro reflective striping for night riding/walking. I also think one can wear them from the bike to a nice restaurant, they are that clean and understated.
Cons: Price. Yes the MSRP is steep but I've owned some MUSA shorts (purchased 2017) which didn't last me very long (over a 2,600 mile tour of the GDMBR). The stitching came loose, making for a disappointing experience. So far rhe shorts and trousers have met or exceeded our expectation for durability.
Good luck,
Jeff & Lori
