A GORE-TEX waterproof layer that weighs next to nothing and packs away to a tiny size, perfect for trekkers and backpackers.
GORE-TEX® TechnologiesMade from a light, low volume GORE-TEX 2.5 layer fabric, the Mammut Juho Jacket will keep you totally dry if you're trekking in wet weather.
Its low weight and simple design make it perfect to wear over your other breathable layers in cold wet conditions, and it's equally useful when worn over just a baselayer if you're somewhere warm and wet.
It can be packed down to a very small size, so it's easy to pack and take anywhere in your kit - or in your pocket.
2 waterproof front pockets
Spray-proof YKK zippers
Elastic drawcord hem, hook and loop cuffs
Casual / Standard

Waist: Measure the natural waistline.
Inside Leg: Measure from the crotch to where your trouser is normally worn on the shoe.
Jacket Length: Measure from the centre back of your neck to your hemline. The length measurement will vary depending on the style.
Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet. Many people have feet of different sizes. Fit to the larger of the two.
Bought this jacket on a recommendation against my normal purchases of Berghaus. Wore it once to the shops and home during a rainy day. Was shocked to find when I got home that it was wet inside the hood, shoulder and upper arms. Probably condensation but had I been hiking with a pack this would have been as effective as a black bin liner. GO Outdoors Lincoln were great and gave me a refund so that I could buy a Berghaus. Funny enough the next day was raining and I completed the same walk, bone dry this time.

Wore the jacket once, got wet, took it back for refund, told it had to go back to Mammut for warranty claim. After a small discussion, it was decided i could have a refund.

Mammut Juho jacket not waterproof
I thought that, being Gortex, I had purchased a solid waterproof jacket. How wrong I was. I have used it twice in the rain and got completely soaked both times. Water just seems to soak through the material. Very poor.

Avoid at all costs , bought this with high hopes to use a ynot festival because I knew the weather looked sketchy to say the least .water came through round the neck area and cuffs just seem to draw the water up .not impressed having said that go outdoors were brilliant on changing item with no fuss.

Jacket leaked badly
This jacket leaked badly on its first use during a resent trip to Snowdonia. my son was soaking wet by the time he got to the summit on mount Snowdon while I was fine in my Sherpa Lithang jacket. I'm going to try reproofing it with nikwash txdirect , but if it still leaks I will take it back for a refund and put that money towards another jacket.

Men's Mammut Juho Jacket epic failure
Bought this last Autumn before a camping in Scotland and worn three times since, the last been when I was actually caught in a shower whilst camping in Wales last week. During the Wales trip although the one and only shower wasn't heavy the jacket failed on an epic scale with rain soaking straight through...Gutted. I thought I had bought a decent product.
Will be contacting Goretex to have the jacket either replaced, fixed or refunded.

Mammut Juho Jacket
A fantastic quality jacket from Mammut! Beautifully made!
Haven't tested in the rain yet but being Gore-Tex I'd expect it to handle the best the British weather can throw at it.
