In reply to Wee Davie:
I think you've right regarding bulky gear 'back in the day'.
Clothing is certainly less bulky these days, although people now carry big belay jackets these days, filling up this excess space! Another observation, folk used to wear everything, climb without bags, now they wear less, but climb with sacks (belay jacket inside).
Anyway, the Ice Star was an awesome pack, though was yours not the red cordura one? I used to have a 25L VauDe pack, purple down one side, yellow covering the rest of body, some bizare black, useless pocket, with buckles, facing rear. My friend, Elsie, has been using it for years, the retro styling, complements her 'hill' look.
38L would seem about right for Scotland, everything inside, walking in just wearing a thermal.

Ps. Toby, I'll bet that Ice Star, probably lighter than several 'go faster' packs these days. Have things really evolved in 20 years????
