      Hi all, I’m looking into purchasing a pair but I enjoy wearing denim year round and need something to make it a tad less miserable.

      Currently wearing PBJ 14oz and doing fine in 70ish degrees and I assumed to get the 14oz in IH as well but on Reddit was told that the 21oz is more breathable and therefor a better option.

      What do y’all think?

        Lighter oz doesn’t mean more breathable. I think 21oz is the most breathable IH denim I’ve had. But, I haven’t gotten to try the SLB slubby denim yet, and by all accounts that’s the best.

          21oz is such a amazing denim and very breathable if were tslking about the indigo version. I had a slubby and imo that’s the most breathable denim but overall i think 21oz is the perfect 4 season denim. But that’s just my 2 cents

            Yes, I also admit that my 21 oz is the most breathable fabric among the other IH denim's that I own. I had it on when it was humid outside and it was not that bad.

            IH-555N | IH-666S-21 | IH-777D | IH-666 XHS | IHG-035 | IHB-06 | IH-721-KHA
            IHSH-251 | IHSH-07 | IHSH-246 * 2

              Slubby is the coolest most breathable denim we make

                    I can confirm that the SLB denim is perfect for warmer weather.

                        I haven't tried the 14oz denim, but I can attest that the 16oz slubby is very breathable indeed, and is lovely and soft.

                        Take the dive...

                          By a wide margin slub among the ones I have tried. 21 may actually breathe a bit more that 14 but don’t quite me on that.

                          Think it, be it.

                            To chime in on the 14oz department and it’s only my opinion so could be wrong.. but 16oz breaths more, then 21oz and then 14oz but it’s just my first 14oz and i only tried it on for like seconds 🤣

                                Totally newbie, so take my comments with a grain of salt.

                                I find that the 21oz wears cooler than the 16oz slub (to me).

                                  Hi all! For me, the thinner weave, the easier it is in the heat. In the sun, any dark-colored jeans are hot. There is no universal option. In softer and worn out jeans, it will be more comfortable.

                                    Any plans for a restock on the 634 SLB?

                                      This may be obvious, but regardless of denim weight, a looser fitting cut is going to breathe more than a tighter fitting one. I found my 633N 17oz to be the most comfortable in hotter temps compared to my 14 and 21 oz, but a looser fit helps.

                                        @moto Completely agree with fit and cut plays into the breathability and comfort levels.

                                        Great observation and advice!

                                            I don’t own a pair of the slub 16oz, but I have a few pairs of 14, 21 and the 17N. I wear the 555 17N, so even though they are pretty snug, they are very wearable in hot weather.

                                            I wear the 17N as a cook in a pretty hot kitchen, but on crazy hot days like 30+ days I wear a pair of 12oz wabash a size too big.
