Hey, Ive been to the Gaspe Peninsula! For a travel story. Thats about as far from where I live as you can go and still be in North Americaplane to Boston, plane to Quebec, lo-o-ng train ride up to the peninsula. Gah, took forever. But I had a good time. Found a fabulous restaurant on a hill outside of Perce, I think it was, and pretty much camped there each evening. Wonderful lobster, and cheap. Lots of wine, too. Did some kayaking, hiking, bird-watching. Pretty place. Love the people there.
Anyway, I was there in August. I imagine winters can be fierce. So youre likely going to need a moderate-size day pack to carry extra clothes, food, and emergency gear. Something around 30 to 40 liters (1,800 to 2,500 cubic inches) ought to be the ticket.
Heres one: The Arc'teryx Bora 35 ($146 Canadian). Nice day pack for snow sports, with watertight zips, lots of storage points, pockets for skis/poles, and a great suspension. I also like Gregorys Z35 (about $175 Canadian). A bit larger than the Arc'teryx at 35 liters but still a compact, close-fitting pack. Excellent suspension, plenty of packing options, sturdily made. I have the slightly smaller Z25 and like it very much, but that may be a bit too compact for winter.
What do you put in said pack? Enough so that if you break an ankle and it turns dark, you live. That means an extra fleece jacket like MEC's Reactor ($135) or Patagonias down sweater ($250 Canadian), and a bivy bag like Integral Designs Microbivi ($147 Canadian), and maybe a compact stove and fuel like the Primus Express ($52 Canadian). Plus SPARE gloves, hat, and socks, in case what you are wearing at 5 p.m. gets wet.
My advice, get the lobster. And a gin & tonic.
