The Aegis Series offers a protection level similar to the Cyclops, but in an inverted design. Aegis cases features an inner-layer of shock-absorbing silicone with an outer-layer of hardened polycarbonate. This makes the case easier to slide in and out of pants pockets. Most of these cases also feature silicone plugs over port openings but have a stick-on type screen protector and installation kit. Is the Aegis right for you? These cases are for people with active lifestyles who need durable protection, but in a slim, portable design, perfect for those who may be keeping their phone in a duffle bag or purse or in and out of a pants pocket all day Type: Case & Covers Compatible Phone Manufacturer: Samsung Galaxy S II SGH-T989
