Fits BOB XL no problem. Takes 5-10 minutes
"Got the jacket for my BOB XL. Fits great. No issues. Other reviews said they couldn’t get it on? I have no idea what they are talking about. It’s suppose to be snug. Some said they needed 2 ppl?… Weak. I did it myself took me 5-10 min. It’s a bit tight at first but work from the top to bottom. And make sure the arms are in the appropriate place so your not fighting the shoulder width. Went on like a glove. Not sure how long it will last but def recommend."
