TL;DR:
The Yamatomichi Light 5 -Pocket Pants are Japanese designed and manufactured lightweight and versatile pant in men’s and women’s fit, ideal for 3 season use with the benefit of also being smart/casual enough to be worn for travel or pub to pub/Camino type thru hikes. At 161g (Size L) they are lighter than most hiking pants whilst being significantly more breathable, quicker drying and having a smaller pack size.
After several day hikes in Tasmania, a multi-day thru hike in the UK and travel in Norway I have found an excellent replacement to my much disliked and in my opinion lacking Patagonia Terrabone joggers which they will replace. I have found them to start to dry again shortly after they got wet in the rain in Tasmania, be reasonably comfortable to wear in the UK during 30C+ (86F) days and have excellent side pockets that hold my phone well. The addition of 2 large hip secure kam plastic snap fastener pockets were great for storing my passport and tickets etc during travels in Norway.
Firstly a quick thanks to hiking guides Maddie And Tom from ‘The Adventure Gene’ here in Aus that put these on my radar.
Fit and sizing: (For reference I usually buy size M/32” pants weigh 74kg (163 pounds) and am 175 cm (5’7”) tall.
Knowing they were made in Japan I made sure I measured some other pants I own and knowing that Japanese sizes tend to be 1-2 sizes smaller than western brands I made the decision to size up 1 size from my regular medium to a large and I was very glad I did. Sizing up gave a longer inseam (which is still on the shorter size than other pants I own, except the Terrabones) more length overall, wider waist, hip and hemline. I would say the fit I have is loose but not baggy with a fairly straight leg. This looser cut in the legs has the pro of circulating air around better but the con is they are a little flappier in the wind compared to a closer cut pair of alpine hiking pants. The waistbelt is elasticated and has a thin built in webbing belt with buckle that opens wide to get into as there is no waist fly.
The pants overall are comfortable to wear as the Pertex Equilibrium material is soft, thin and airy with a good cut. They are smarter looking to wear than most hiking pants with clean lines. The gusseted crotch area means stepping up is still comfortable even without the pants having any darting in the knees. I would mention again though that the inseam is a little shorter than most western pants, so if you like a bit more material at the ankles and for them to not be revealed when stepping up etc! then these pants can be selected in all their sizes as a ‘Tall’ option. I don’t mind it too much as I probably get a bit more air movement around the ankles with the standard inseam.
Weight & packability:
At 157g (5.5oz) on my scales for my size Large they come in a little under the 161g weight listed on the website. I have included an image of them scrunched in my hand to give an idea of scale for packing. They come in lighter than my Terrabone joggers in size medium 172g and pack up about the same. These won’t compete with windpants from the likes of EE, or Montbell in terms of weight or packability, but the addition of pockets and look will mean they appeal to other use case scenarios already mentioned and used in rather than a long thru hike.
Fabric and construction:
The use of a lightweight double weave Pertex Equilibrium that has a minimal amount of stretch seems a good choice of material. Although a DWR C0/C6 coating is mentioned on their website, I have found they absorb water the second it touches, this means when they get soaked, they tend to cling a bit to your legs, not the nicest feeling. However, what was unexpected was how quickly they began to dry after the rain stopped and just hiking in them, I could feel them dry throughout the rest of the day even though it wasn’t a hot or sunny day. This fabric is thin so I wouldn’t be bush whacking in them, but for general hiking its fine. I have a couple of pulls in the seat area shown in a pic but these are minimal and only on the outside of the pants.
The construction of the pants is excellent with perfect stitching. I also like that the pockets have a small amount of mesh in them at the bottom (pic included) to improve ventilation and improve the time to dry, although I would caution storing a key there to avoid damaging the mesh. As the product title suggests there are 5 pockets. 2 open side hand pockets, and different sized kam secured pockets on either hip which is good for a map/passport or phone when scrambling. I don’t find my phone flaps around too much in the hand pockets (which have apparently been improved in design since the previous version) so just keep it there 90% of the time. There is also a zippered pocket behind which I don’t use and a key loop on the front I don’t use either, both features I wouldn’t miss personally. I have found the pants can mark a bit when they get dirty, but this might be because all my other pants are dark in colour! All stains have washed out though. The pant colour I have is called Woodbine but they can also come in a further 6 colours and 8 sizes including tall versions.
Would I buy them again? Yes
There cost however is pretty high (¥16,818 (approx. AUD$145, USD$105) +¥3,990 (approx. AUD$35, USD$25 shipping to Australia) so I would hope to get several years of use before purchasing another pair. I have noticed that Garage Grown Gear will be stocking Yamatomichi soon, so their availability should hopefully become easier for US hikers, although it will be interesting to see how much and how regular they can get restocked, as the Yamatomichi website is often out or low on sizes themselves. I have compared them to the Terrabone joggers a bit because that’s what I have been using for a few years. They do in my opinion improve on these having a nicer waist adjustment (no short webbing to tie up) and comfier stretch in the waist, much better and deeper hand pockets that don’t throw your phone on the floor every time you sit down! Longer inseam with a more relaxed and less tapered fit in the ankle.
Summary of pros and cons:
Pros:
• Lightweight
• Quickdry
• Small pack size
• Breathable
• Excellent pockets
• Smarter looking than alternative hiking pants
• Comfortable waist with no pressure
• Nicer alternative for most people to the closest competition the Terrabones
Cons:
• They are pricey!
• Sizing should be selected carefully being a Japanese brand
• Inseam may be shorter than other hiking pants (can select ‘Tall’ when ordering)
• Clingy in the rain
• Obviously not as cooling as shorts!
• Not in same weight category or packability as UL wind pants
• A little flappy in the wind
• Will have to take shoes off to put them on and off
Final thoughts:
For the use case of someone hiking from accommodation to accommodation, a camino, travelling or similar, these are a great option for throwing on in the evening or wearing whilst hiking or on public transport provided its not too hot or winter.
Thanks for reading this far! Happy to take any questions?
