REI Summit Winter Poles

REI says:
Made in Austria exclusively for REI, these aluminum winter poles are ideal for snowshoeing and winter trekking. Strong, two-section telescoping shafts extend to 57 in. for use and compact to 33.5 in. for storage and packing. Twist-to-lock, steel-reinforced, locking mechanism ensures your poles stay at the proper length while in use. Ergonomic grips provide sure hold and wide, buckle-free, adjustable straps support wrists. Profile grip zone on upper section improves gripping ability in wet conditions. Carbide tips are reliable on a variety of surfaces; rubber protectors extend the life of the tips and protect your gear when stowed in a pack. Large snowflake baskets provide flotation and stability in powder and packed snow conditions; baskets twist on and off easily.
