Why We Like The Fjallraven Keb Trouser

Fjallraven's Keb Trouser is made of stretchy recycled and organic G-1000 fabric for serious freedom of movement and durability. The knees are articulated and have extra-song seams so we don't blow them out, and zippered vents and an extended fly help keep us cool if the going gets hot. Fjallraven also included adjustable cuffs with boot hooks to keep grass, dirt, and snow from sneaking down into our socks

9/10 hiking pants

1 year and 1000 km's on these pants in the woods, trails and mountains, during 3 seasons. I had 1 small tear in the bum from shale rocks, other than that, they have been extremely durable. My local Fjallraven outlet has since repaired and waxed them for free. The 4 leg vents, when opened, create a nice draft to cool off your legs. Also, you can easily roll up the pant legs to just below your knees to cool off further. The right leg pocket has a cell phone spandex slot inside which is awesome, the left leg pocket has a zipper under the button flap. The bottom of each leg has a metal hook inside the folded layer to attach to your boot laces, to keep the legs taut when needed, but is otherwise completely un-noticeable. The 2 front belt loops have extra loops directly under them, for carabiner clips, which I use regularly. The stretchy fabric (usually the lighter colour of the 2 colours) is incredible and I cannot hike without it after seeing its performance. One can easily move without restriction. The tough G-1000 fabric (usually the darker of the 2 colours) is fairly tough and does feel heavy or discomforting at all. My only complaint is *NO bum pockets* . However, a Fjallraven outlet will supply you with color-matching fabric to have another tailor make bum pockets for you. 9/10 hiking pants. (Pricing losses 1 point) The free tailoring, repairs and annual waxing helps justify the pricing a little bit. But I recommend you buy them on sale TBH.

Best pants ever!

I have had two pair of these pants for a while. These are the best pants ever! I bought some for my fiancée when we were dating and we got engaged wearing the kebs as well!! They can get a little hot in summer time/tropical climates but in any other temperature other than super hot these are the go to!

Amazing pants expensive but in my case worth it

I've had 2 pairs of these for almost two years and I wear one for work and one for home and the one for work has lasted me the entire time with no damage even though I work civil construction so basically the apps are the flexibility is very well designed and the material is surprisingly durable the down is they are very expensive but honestly at this point they might even out

Great pants terrible order experience

I returned this product before using it
Size Bought:
38/us received 42
5' 8"

The pants fit really small so I ordered up a size while the other fjall raven pants I own. Backcountry sent me 2 sizes up and then the exchange process took almost a month. They sent me an RMA I shipped back and I couldn’t track. The representative said I would have to wait for the returns dept to show as received before they sent the other pair to me. I ordered these for a trip that was upcoming. I have had other returns with this company and they always disappoint. This will be the last time I order from backcountry. Would recommend the pants but order from somewhere else.

size up!

My boyfriend is always a 36 and got these in a 38 based on reviews. The 38 fits like a 36 around the waist, with more room in the leg. I think a 36 would've been way too tight on his legs which wouldn't be comfy for hiking. The 38 is great for him, roomy in the legs, allows for alot of movement, and a little bit of extra room around the waist. Lots of reviews on reddit say to size up - I agree. He is 6 foot about 215lbs and the 38 was great (typically a 36). Material feels amazing too.

comfort and durability!

stretchy fabric makes it very comfortable and tough material in knees and below leg area is tough for any activity great for hiking and camping

You'll never go back to any other outdoor pants

Amazing pants, you'll never go back to any other pants for being outdoors. Camping, hiking, etc. The only issue I've found is I owned a pair pre fit-update and now I am a 52 instead of a 50. Make sure to take this into consideration and perhaps size up.

The Perfect Pant

This are the standard pant that I use to compare any other product. They fit incredible, have amazing durability. Plus you can wax them and make them waterproof. These pants truly are the only pants you will ever need for the outdoors.
