Intended to boost your well being as well as your heart rate, the new athletically patterned Endorphin garments are perfect for high output aerobic sports like running, adventure racing and trail hiking. Made with lightweight, air permeable textiles that wick moisture to dry perspiration quickly, Arc'teryx continues its tradition of using different fabric panels to offer both stability and freedom of movement where needed.

The new Kapta Zip SS (£50) is a super versatile short sleeved shirt that easily makes the transition from high output outdoor activities to indoor workouts. The stretch pointelle knit fabric wicks moisture well and offers superb breathability, thanks to the polyester mesh panels under the arms and on the back.

The new Cita Series offers athletic bras, tops, tanks, and tights for a variety of fast-forward activities - blending the stretch of polyester for mobility and support with the odor management of X-Static to increase long-term comfort. The Cita Tight sports Scotchlite reflective trim on the thighs and knees for improved visibility in low light and power mesh on the lower calf for optimal muscle compression and thermal efficiency.

Arc'teryx's groundbreaking Phasic Technology also expands into the Endorphin collection in Spring 2011, with the addition of the Motus Crew £40/LS £45, which utilizes the lightest Phase SL baselayer fabric to rapidly transport perspiration during the active phase, disperse this moisture across the garment in the recovery phase, and dry out quickly while at rest.

Ideal for switching between active and urban environments - the new Solita Jacket £120 is engineered to deliver regulated warmth, comfort, and versatility. This fully-zippered-go-anywhere jacket is made of moisture wicking brushed polyester that is perfect for warming up or cooling down before or after strenuous activity. The new Solita Short and Skort feature snug-fitting stretch polyester around the waist and a lightweight stretch woven polyester on the legs and skirt to deliver high performance mobility for unrestricted movement during runs or other aerobic pursuits.

Wearable across a wide variety of seasons and conditions, the new Trail collection offers breathable, quick drying, and compressible items that can be easily pulled from the pack when needed. Perfect for backpacking, hiking, and rock climbing in spring, summer, and fall, innovative stretch textiles offer a superb range of motion, which is further enhanced by movement specific articulation and patterning.

The new women's Mentum Series is available in sleeveless, short sleeve and long sleeve technical crews as well as an active wear skort, with each style utilizing moisture-wicking single-knit polyester jersey fabric with spandex that stretches and dries quickly. The smooth outer face and flat locked seams make for frictionless layering over top. Designed for versatility, the new Soltera Hoody £70 is made to function in the most wide-ranging environments; city to trail and all point in between. Ideal for aerobic, motion-oriented activities, this casual hoody is made of stretchy, breathable single knit jersey fabric that has a brushed face for added comfort. Convenient front hand warmer pockets provide ample storage and a concealed key pocket keeps incidentals safe.

Also brand new to the women's 24 category is the trim fitting Destina Shirt (£45/ LS £50) – two new lightweight tops designed for casual comfort. Ideal for a wide range of adventures, these shirts feature a banded V-neck collar, longer body length and anatomical shaping on the bust. The SS sports tulip style short sleeves for enhanced freedom of movement and the LS captures its style with three-quarter length arms and a hip length, trim silhouette.

Made with a lightweight cotton/spandex textile for fit and comfort, the new Moveo Strappy Tank (£25) and Moveo Tank (£30) are ideal for warm days spent bouldering at the crags or doing day-to-day errands. Perfect when paired with a sports bra underneath, these loose fitting tops feature easy moving comfort and the shear, gauzy fabric takes the sting out of hot weather. Luxuriously soft, lightweight and durable, the Moveo styles will keep you moving, regardless of where you're going.

Using a wide variety of technical fabrics and innovative designs, the Spring 11 women's line is a complete collection of products of uncompromising quality that provide maximum freedom of movement while still shedding the elements and standing up to constant abuse.
