i got your solution:
step 1: Get hefty black garbage bag, proceed to cut holes in the bottom.
step 2: Insert legs through these holes, and tie using the handy drawstring.
Step 3: throw on a few layers of cloths.
voila you will be dry! at least your layer under the garbage bag.
Ps just dont let that darn yellow string stick out. wont pick up any cute snowbunnies like that, thats for sure
