A low pressure drop device for personal protection against toxic industrial chemicals and chemical warfare agents has a flexible polymer hood impermeable to toxic challenge molecules, a neck seal for sealing the hood about the neck, a half mask for connection to a canister and a low pressure drop canister for chemical protection. The canister contains carbon monoliths of 5- 40 mm diameter, length 1-3 cm, open area 30-60%, surface area &#x2265;700 m/g optionally activated to &#x3e;30 wt % weight loss and optionally impregnated with metallic additives and/or triethylene diamine. The monoliths have square channels of size 100-2000 &#x3bc;m and wall thickness 100-2000 &#x3bc;m. It also contains a resiliently flexible closed cell foam with holes slightly smaller than the monoliths so that flow through the canister is through the monoliths.

Personal protection device using monolithic activated carbons

Brassieres are provided which provide enhanced levels of comfort and support to the wearer. In one aspect, the invention provides a brassiere comprising an elastic material and damping arrangement, wherein the damping arrangement is arranged so as to dampen movements of a strap of cup caused by movement of a breast. In another aspect there is provided a brassiere having a strap and cup arrangement which is configured to distribute the breast load. Also provided is a brassiere for constraining movement of a wearer's breasts during wear, wherein said brassiere is configured such that movement of one breast caused by movement of the wearer is restrained by a remaining breast.
