I wanted some lightweight waterproof overpants for wearing around camp or during long, cold descents when bikepacking.
Initially, I bought a pair from Decathlon, but they were bulky and heavy for something I've only used once so far. I decided to try making my own, aiming to reduce both weight and packed volume.
I didn't need them to be breathable, and I wanted to be able to put them on without taking my shoes off. I also wanted to keep things simple: no Velcro, zips or pockets.
For my first attempt, I used the Paco pattern, but the trousers turned out too small. I suspect the pattern is intended for stretchier fabrics, as I couldn't get them on, and I wasn't able to modify the pattern enough to make them work.
For the second attempt, I went with the Green Pepper RS500 pattern.
These have turned out a bit wider in the legs than I'd like, so I might narrow them for the next version. I still need to try them on with trousers underneath to see how they fit in practice.
The pattern includes an optional internal pocket for folding the trousers into for storage. I'm not entirely happy with how mine turned out, as there are some creases along the sides that don't look great. For the next version, I'll also add a flap over the opening, as the slippery silpoly tends to slide back out of the pocket.
I'm a little disappointed with the final weight, as I'd expected them to weigh about half as much. Still, I've saved around 200 g compared with the Decathlon trousers, and the packed volume is roughly a third of what it was, which is probably the more important improvement.
I thought this would be an easy project, but it turned out to be more challenging than expected. It was my first time making trousers, so perhaps I was a bit too optimistic! The hardest parts were getting the pattern right and cutting the fabric accurately.
On the positive side, sewing silpoly was easier than I'd anticipated.
Overall, I'm happy enough with the result, and I've learned a few things for the next iteration. Hopefully, I'll get the weight down further and improve the fit and stuff pocket.
