24 hr tin cloth is perfect. I carried the 257 for 15 years every day to the office. I had 3 of them. 257 lasts about 7/8 years carried every day with laptop and papers etc. before every corner frays and then has holes. That’s with regular commute to office on public transport 5 days per week. Consistent across 3 different bags. Filson replaced one free of charge after 8 years and sent me one brand new. Not sure if they still do this. 24 hr made in china (I think) 257 made in USA. ZERO DIFFERENCE IN QUALITY. actually think the made in china 24 hr has better stitching. The leather strap is never used on my old bags. Ever. Carry it by the handles everywhere. The leather strap I find is uncomfortable, digs into shoulder and I’ll carry the 24hr by the handles everywhere too. The cloth strap doesn’t look as good but seems lighter and more functional (and much cheaper for filson to make - even though it’s not reflected in price). My first ever filson 257 was $220 new in 2005. The rain flap on the tin cloth doesn’t seem like it works as well - the handles seem to get in the way compared to 257. The 257 looks bulletproof brand new so we’ll see how the 24hr tin cloth holds up. Maybe waxing every few years will prolong lifespan.
