I did and honestly wasn't that uncomfortable. But it was disappointing.

Some pics.
This is what I carried with me. Camelbak MULE and a Eddie Bauer jacket with WeatherEdge Plus (supposedly like Gor-Tex)

Yes that is an MRE in the pack. Plus a long sleeve shirt and change of socks, not to mention the "Oh Shit" sleeping bag. Some other small items as well. Probably about 15 lbs.
The MULE is really not designed for long hikes. The waist strap doesn't really work so well on keeping the weight off the shoulders.
Some pics from going up and coming down, no real order.

See the blaze for the trial? Goes all the way up.

Parts of the trail were quite muddy.

Sounds like a good time.
Check out Helly Hansen rain gear. I've been in some shitty situations with dirtbikes and mountain bikes, and this gear has held up.
Heart Lake is wonderful, I went last year on a windy mostly sunny day and got to the top of Rogers Pass.
