Depends on how bulky, I'd think.
My friend has one - is 5'4" and 220 lbs and it works - but he warned me not to get that size because at 5'7" and 105lbs, it wouldn't work.
I'm thinking of the Mr. Limpy XS, but I haven't decided yet. I've seen some nice packers off-site, too. I've considered just waiting and investing in a LolaJake when the time is right.
But for the price of the Limpy, it's not a big deal if it doesn't work out, I guess.
