There are many types and brands that advertise "liners" or "speed" versions of pads, but I have found that only a few are worth the dollar. First, I recommend the Maverik Maybach Speed Liners. They are light and comfortable, as advertised. Second, I recommend the Warrior MPG UltraLyte 8.0 Lacrosse Shoulder Pad which are your best bet for some protection, but less than the Maveriks. Lastly, I recommend this unconventional method of getting comfortable, but compact pads: Warrior MPG 4.5 Lacrosse Shoulder Pad. Don't "diss" this idea just because they are "beginner" pads. I actually still wear these because they are so small and compact. When you get them in, you need to cut the shoulder sum and plastic piece off nearest the neck. This oprion is the cheapest and in my opinion, most comfortable way to go.
