Familiarity: I've used it several times
Fit: True to size
Use it on Elbrus mountain in july. Was very strong wind, but feel fine in this jacket. Ventilation is not very good, i was wet sometime. And not enough length. Felt cold on back when sit down.
Quality is good.
For winter alpinism need something warmth. Especialy in Russia.
PS. Sorry my English. =)
