Protech makes a nice sunscreen. It includes a moisturizer, SPF is 30+, provides high protection from UVA types I and II and UVB rays, and it's fragrance, oil, and PABA free. Since it's oil free, it absorbs quickly and lets your skin breathe. What makes it really interesting for lightweight backpackers is that it is now available in 0.25 oz tubes (good for about 4-6 applications on the face and neck) and single application foil packs. No more filling those little pots with suncreen before every trip, just grab a tube or a few foil packs.
