    Simone mountain pants

    Great trousers for walking and mountaineering. I use them summer and winter with a pair of thermals. Great fit and stretch. Perhaps a reinforced seat would be a good addition.

    Definately NOT winter trousers :)

    I didnt read the description before putting these on for a 5am -7deg hike. I wasn't frozen, but i can say for sure i wasn't warm! With some light leggings or shorts i'd have been a bit warmer round the backside.

    That aside, they are a great fit, perfect length and waist for me im a UK 32 and bought the Size : 42 US:S/M.

    The only reason they are not 5* is id like to have one more pocket somewhere.

    Pohodlné kalhoty

    Pohodlné kalhoty, částečně z elastického materiálu. Padne i vysokým štíhlým postavám, což bývá problém sehnat vyhovující střih. Nedávám plný počet hvězd, protože jsem zatím nevyzkoušel prodyšnost při vysoké intenzitě.
