Sizing Information:
Choose a jacket size based upon what you normally buy in men’s clothing. If you want to measure yourself to help pick a size, have a look at Alpinestars’ sizing chart. And for those who may have a bit of a belly, we encourage you to consider our estimated max belly sizes listed below. Choose a jacket size that will accommodate both your chest and your belly.

The 7-10 WP jacket consists of a heavy duty abrasion resistant textile shell with a waterproof/breathable inner liner. With an inner liner this jacket claims to 100% waterproof and while I normally warn folks that no jacket is really 100% waterproof, this one probably comes pretty close. The use of the inner liner and also the fact that this jacket doesn’t have external vent zippers will go a long way toward being truly waterproof. The absence of any venting though will make this jacket a cooker in hot weather, so consider this style for cold to mild weather and wet weather. Speaking of cold weather, this jacket comes with a very nice full sleeve thermal liner which will keep you warm down to very low temperatures. The jacket has a full connection zipper so you can attach textile or leather pants from Alpinestars. Take the “View Larger Pictures” link above to see this jacket’s features in detail.
